Right now, I've a Proxxon PD400 Lathe, a Sherline 4410 lathe, a Sherline 5410 manual mill, and a Sherline 2010 mill which I've CNC'd. This blog is like a journal of each session I had in my little shop, which in fact is a converted study. Despite started 2 years ago in this hobby, I still consider myself a newbie.

The flow of molten PLA not consistent. Ruth rejected it and ask for a reprint. <br /><br />While I was looking at it, a thought suddenly came upon me:<br /><br />The cross is not a beauty, nor it is even at least pleasant. It is rejected by all, forsaken by God. <br />It is in that One Act; the act of love. An act so complete that made it so beautiful. <br /><br />It is in that One Act that we can come boldly in the presence of our Father with no shame & guilt.<br /><br />He died that we might live. He became poor for our provision. He was made sins so that we can have His righteousness.<br /><br />This is my Jesus...<br /><br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5757503500246689906'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj24fEInvhPh-wUr3u3SbF_UVWFf9G4LPPJaNgzUDqit-oveO69dqwgEf_g14KZnl9FfyeiQjPtA2uz7yFQuUfwRgLtuAdbNxq0zlXmtFsIWfJ2acWT-DuBEt3E5jplm3iyrZ4Vksb6bVg/s288/6.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br /><br />- Posted using BlogPress from my iPhone<br />Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com0tag:blogger.com,1999:blog-7445819594773958579.post-81409675373582212142012-06-17T14:29:00.001+08:002012-06-17T14:30:00.885+08:00Wongster's Production Has Moved!Hello all,<br /><br />There seems to be no update for a while but in fact there are.

But I think you know what I am referring to. <br /><br />This post is not about making the transfer screws as the set I bought is now sitting at the Post Office waiting for my collection. It is about my attempt to make the point like what was shown on Bob Warfield's website (www.cnccookbook) as shown below:<br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5747255656501389394'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcrg7HCAk4TJ9UiWp7I5G8wCrNFMhN1w5Qfg7aGAafSi1157irK75XJBsbZGe0YXltRXVgAdI6y5OVrbJGh8f8OzMuJahcSkW-n4L-LxQtw7tlbOv2xIHtj5seGNt8NiZ8U0BGOXALbQo/s288/4.jpg' border='0' width='281' height='211' style='margin:5px'></a></center><br />I've been wondering how he did this. What I did before was to have the base of the point (which is basically a cone) equals to the diameter of the rod or screw. <br /><br />This morning, before leaving for work (I know it's Sunday and it sucks to be working on the Sabbath), I did an experiment. An M6 cap screw was mounted in the 3 jaw with its hand sawn off using a hacksaw. The top slide was turned to the 30-degree mark on the graduation and advanced to make the cut. I tried stopping at around the same Z depth and in no time, I get the result I want:<br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5747255752318290402'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfS3ayYSE22g72JqqKhNIZ75BvKjaC7FFHk9yzfnQeBwAt7O725AOv635hJ6b2PV4V7VJr427GzrT8jRDfgrLGsoT7ALELbSqtYQGZOux13-0r_7FB0AWzYmapnCAxt7gZlfNodR74MGg/s288/6.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br />That made my day!!!<br /><br />The point wasn't hardened. It works alright on aluminium but could stay sharp for a single use on steel. If you observe the pic above carefully, you'll see that the tip is a little blunt. This pic was taken after testing on both aluminium & steel.<br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5747258680585430242'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEim3SKJ-8J5C1osuCMKDCHKxnqb_sz7ShHQAkNRHSMtXZD1-0GEjpdHkY3ZktnFiGm6dClmxNYhDvPJyW82dfCUIVOTtDyC6kHWjFYEQxb3cZDn1ZV4AufTVqEJWYTLH80PUbes86vpT6w/s288/9.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br />This was when the piece just came off the lathe. <br /><br />But I still leave for work happily as I now know how it is done. <br /><br />- Posted using BlogPress from my iPhone<br />Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com0tag:blogger.com,1999:blog-7445819594773958579.post-2915272845189446572012-05-27T07:43:00.006+08:002012-05-27T07:43:53.499+08:00Broken Lathe Guard and Noisy Belts<span style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; display: inline !important; float: none; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;">I had a surprise the other morning when I saw the acrylic cover on the lathe broke from its swivel base. I don't remember breaking it during the last session as that will be pretty obvious looking at the way it is broken.<span class="Apple-converted-space"> </span></span><br style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" /><br style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" /><span style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; display: inline !important; float: none; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;">Anyway, there is a magnet at the swivel base that cut off power to the lathe when the cover is lifted up. It does gets in the way when turning big diameter stock close to the spindle but it prevent accidental touching of the spinning spindle when in operation.<span class="Apple-converted-space"> </span></span><br style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" /><br style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" /><span style="-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: white; color: #666666; display: inline !important; float: none; font-size-adjust: none; font-stretch: normal; font: 12px/20px arial, verdana, sans-serif; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;">I wonder if I should replace it or Loctite the magnet on the swivel base to allow the spindle to work without it. Those safety conscious folks may jump with it off but... I don't know. Will think about that.<span class="Apple-converted-space"> Anyway, I ordered the replacement and it should be on its way from Germany.</span></span><br />

<div>
<br /></div>
<div>
The decision would be simpler if I'm able to write once and post on both, pics and words, all at one time. But so far I've not been successful. Posting both sites requires quite some bit of work, especially with pics.</div>
<div>
<br /></div>
<div>
What's your preference?</div>

<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">I was rather curious to find out if the recess fits the bore on the spindle flange. Went back to the shop and take everything off and fit the work.</span></div>
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px;">It seems to fit nicely...</span>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px; text-align: left;">Pushing the flange of the chuck to be against the flange with one hand, I tried moving the chuck against the registration boss on the flange. I can feel slight movement and some knocking sound at certain point... boy am I disappointed...</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><span style="background-color: #fafafa; line-height: 18px; text-align: left;">I put on the 3 jaw chuck (without the bolts) and did the same. The slight movements and a little knocking sound was also there.</span>
</span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px; text-align: left;"><br /></span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; text-align: left;"><span style="line-height: 18px;">I measured the gauge with the caliper - 70.01mm. The registration boss on the spindle flange measures 69.99mm. That means that the recess is 0.02mm over sized... No wonder the gauge fits so tightly into the recess of the 4 jaw chuck. I've to press it in with my hands. If the gauge is oversize, the recess will also be...</span></span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px; text-align: left;"><br /></span><br />
<span style="background-color: #fafafa; font-family: Arial, Helvetica, sans-serif; line-height: 18px; text-align: left;">I'll push on till the end to complete this project. The decision of making another piece will be left till the completed collet chuck is tested.</span><br />

Wanted to sleep in on this Sunday morning but just could not.

I asked Dave my last couple of questions on the forum so that I've clear images in my mind of how I should carry out this operation.</span><br style="background-color: white; color: #666666; font-family: arial, verdana, sans-serif; font-size: 12px; line-height: 20px; text-align: left;" /><br style="background-color: white; color: #666666; font-family: arial, verdana, sans-serif; font-size: 12px; line-height: 20px; text-align: left;" /><span style="background-color: white; color: #666666; font-family: arial, verdana, sans-serif; font-size: 12px; line-height: 20px; text-align: left;">Not much pics taken as the session was rather short.

The 3 holes are clearance holes for M6 cap screws. After completing the recess, I suddenly realized that I have forgotten to scribe the PCD for the mounting holes... All is not lost, me think.

<span style="color: #666666; font-family: arial, verdana, sans-serif;"><span style="font-size: 12px; line-height: 20px;">This post is also available on my site <a href="http://www.wongstersproduction.com/2/post/2012/05/er32-collet-chuck-turning-the-recess.html" target="_blank">here</a>.</span></span></div>

<span style="background-color: white; color: #666666; font-family: arial, verdana, sans-serif; font-size: 12px; line-height: 20px; text-align: left;">I finally found a suitable piece of aluminium to make the gauge for the recess. It was cut off from a long piece of 81mm diameter rod. No much of convincing required this round to get the piece I want. I've also collected the 80 degree insert tools from Mike. From my reading online, it is good for roughing due to its shape. The pair of left and right tool cost me SGD124 if I remember correctly.</span><br />
<br />
<span style="background-color: white; color: #666666; font-family: arial, verdana, sans-serif; font-size: 12px; line-height: 20px; text-align: left;">With the right stock on hand, I happily turned down the aluminium block to close to the required dimension and slowing turning bit by bit till it fits the recess at the back of the 4 jaw chuck. After playing with steel for a while, I find cutting aluminium fast and easy. The job was quickly completed.</span><br />

I'm now ready to turn the recess. </span>

<br />
Another short session today of about an hour to an hour and a half. The nose is now down to slightly below 50mm in diameter after "smoothening" out the surface. The spindle was bumped up to 660 rpm with very light cut using the Sherline's carbide insert tool. The tip on this tool has radius of 0.4mm. The result was great! The flange was also squared up and finished with the same method. I realised that I've to lock down the carriage to produce a decent finish when face turning. Also, I discovered that having a small relief angle between the edge of the insert and the work helps in the finish.<br />

<br />
When I visit the metal shop at Kelantan Lane, I'll also be buying a thicker piece of Mild Steel stock as the material left for the flange will be a little on the thin side, unless someone tells me otherwise.<br />
<br />
I've been thinking about how I should go about marking out the PCD of the mounting screws. Of the 2 approaches I read, the one shown on an article posted on 7x12minilathe group seems easier. The other one on <a href="http://www.toolsandmods.com/mini-lathe-chuck-backplate.html" target="_blank">Tools and Mods</a> seems to me to be more accurate as it will be concentric to the lathe centre. Any comment?<br />
<br />
Another question, should I be boring and making the taper hole before threading or should I do it the other way round?<br />

<br />
The work on the Collet Chuck for ER32 started last weekend. Up to today, I don't have much to write about. This is the time I'm dealing with a large piece of steel stock and frankly, I've no confident that I can pull through this project to the required accuracy.<br />
<br />
The mild steel stock I bought measures slightly bigger than 100mm in diameter and 42mm in length (or should I call it thickness?). The edges around the circumference was deburred with a file before I started work.<br />

<br />
I took a video of the turning in progress. The chart I've on my lathe says that the spindle speed for steel stock of 100mm diameter is 80 rpm. I tried both 80 rpm and 160 rpm at depth of 0.1mm to 0.5mm per pass with the carbide insert tool. I was trying to see how deep I can cut. Don't really feel comfortable at 0.5mm from the sound produced - it sounded like the motor was going to stall anytime though that didn't happen. To play safe, I backed off from the depth to 0.4mm. Now I wonder how long will I take to bring the 25mm section down to 50mm diameter at the rate I'm going...<br />

I've gotten, so far, from Acrylic Centre at Bras Basah to use for partitioning areas of the bench from flying chips. Lately, as I buy more and more stuff for the shop, I started looking at getting a little more organized.<br /><br />What I've in mind is a stand of sort for my ER collets. I'm likely to make 2; one for the ER16's and one for the ER32's. <br /><br />I've been hearing about Dama Enterprise from various people, in particular, Terence. He shared about the level of service he experienced when he was at the Ubi Road shop. Staff are courteous and helpful. They serve hot drinks and snacks (FOC) while you browse for the stuff you need and when waiting for your order to be processed. I didn't go for the food & drinks but I'm still impressed. <br /><br />I've gotten what I need. Next is to do up the gcode. Hope to have the time to do that tonight.<br /><br />- Posted using BlogPress from my iPhone<br />Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com6tag:blogger.com,1999:blog-7445819594773958579.post-76012019250648943602012-04-26T10:42:00.001+08:002012-04-26T10:42:44.563+08:00Few Things I BoughtI promised myself not to post anymore on the items I bought but lacking any progress in the shop, and to keep my blog from getting stale, I broke it. <br /><br />Over the week and last, 3 parcels were received:<br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5735531684175960722'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5O1wx0YADR6RkkVkz1HE1oApGY9526qubZ52Anv58r0_nHomTYXY7y3Zkhqgux4jTKtAlVwyZVgSzAZGqR7vj_gCRsMFqU0dyuC2ijZPfR9FOZNVijAb3Ie0Re-ljojpPasOUkueLqxA/s288/4.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br />From Arc Euro Trade: Stevenson ER32 Hex and Square Collet Block, Stevenson Metric 10-20-40 & 20-40-80 Blocks, and the 3MT to 2MT open Morse Tapper Sleeve. <br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5735531768169337970'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7N_MRUN4lmM_l2y9CPC-YK13Cb9of8-HuDGRgRKaUmdJ0Ri7paApa14k3utDu-Z5iakx1T2H1m-4Yvp8iXtDxuvO8feWOgF-n33CQPXbwBoFpOIGrgsJDJB-12Ltuur8ab28m5BYelV8/s288/6.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br />From Chrono: Glanze 10mm Parting Tool with 2 spare blades & Centre Square.<br /><br /><center><a href='https://picasaweb.google.com/105298561787733139771/WongsterSProduction?authkey=Gv1sRgCMOcv6zc1Yn1dQ#5735534375067013410'><img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhv0xrozSCqYlIYA8NdTsEvCXSuBetJLIaeh1l4ygqpG0S1b-XZUUrBLcQhaT2AM_hUkNkz7dWBCqlXSjr12PctxJ-DiU6CtlWPfhgfvqKUp4NXZH_HKDJPuKVxPS3wJYhR4LzdWGy54is/s288/9.jpg' border='0' width='281' height='210' style='margin:5px'></a></center><br />From RS Components: 12mm diameter Silver Steel Rod. <br /><br />- Posted using BlogPress from my iPhone<br />Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com0tag:blogger.com,1999:blog-7445819594773958579.post-22134412580320974842012-04-22T20:17:00.001+08:002012-04-22T22:12:28.766+08:00Exploded Diagram of the Half Nut & Apron AssemblyFound the drawing on the Proxxon manual showing the half nut assembly.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://i1207.photobucket.com/albums/bb469/wongstersproduction/Carriage/HalfNutAssembly.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="364" src="http://i1207.photobucket.com/albums/bb469/wongstersproduction/Carriage/HalfNutAssembly.jpg" width="640" /></a></div>
<br />
This part of the manual are all in German. Yahoo! Babel Fish was roped in to translate the parts I'm interested in.<br />
<br />
P/N<br />
36 - <span style="font-family: HelveticaNeue-Roman;"><span style="font-family: HelveticaNeue-Roman;">Klemmmutter: Clamping Mother (Mothers that clamped down on kids???)**</span></span><br />
37 - Blech: Sheet Metal<br />
38 - Nocke: Cam<br />
56 - Stift: Pin<br />
57 - Madenschraube: Set-Screw<br />
<br />
The labeling provided no more insight than when I started. But at least I know that part number 38 is a cam and half nut in German is clamping mother... lolz... just kidding.<br />
<br />
<em>** Edit: I found the actual translation on the web after looking at the exploded diagram of the gear train. In the gear train, the square nuts holding the gears were labelled as "<span style="font-family: HelveticaNeue-Roman; font-size: xx-small;"><span style="font-family: HelveticaNeue-Roman; font-size: xx-small;"><span style="font-size: small;">Vierkantmutter", which Babel Fish translated as "Square". This leads me to believe "mutter" to be "nut". Therefore, Klemmmutter would be deduced as "Clamping Nut" instead.</span></span></span></em><br />
<em><span style="font-family: HelveticaNeue-Roman; font-size: xx-small;"><span style="font-family: HelveticaNeue-Roman; font-size: xx-small;"></span></span></em><br />
By looking at the exploded diagram, I started thinking that I might be barking up the wrong tree. Truth is, from observing that the lead screw shifted upwards when the half nut is engaged, I thought that if I can some how adjust the half nut up a little, I can minimise that movement and I will have lesser of the binding feel when turning the lead screw handwheel. Apparently I'm wrong here. The cam has a fixed position on the apron and the 2 pins behind the half nut have their fixed positions on the cam. These leave me with nothing to play with to solve the problem of turning the handwheel. Till now, the function of part 57, the set-screw, is still a mystery yet to be solved. The fear of stripping its head trying to remove it stopped me from probing further. Could it be the toothed rack that the apron handwheel's gear rides on that needs to be adjusted? What about a bigger handwheel for the lead screw? Would that solve the problem?<br />
<br />
Many questions left unanswered. I wonder if I should do whatever adjustments I can to make it smooth enough to go on to my next project or should I probe further to gain better understanding of how things work together. I've not turned the handwheels of another machines other than my own to know if what I have are already normal. Maybe I should hang around some machine shops, make friend with the owners, and request to play with their bigger machines. An owner of a shop on Toa Payoh Lorong 8, which sported some Chinese made, BP look-alike milling machines, seems friendly. I happened to walk past last year after visiting a client in the next block and stood there a about 5-10 mins watching him working on his mill. He turned around, saw me, smile, and went back to his work. I also have a client who owns a manual machine shop in Tampines Industrial Park. May be I can asked him if he is willing to allow me some time on one of his machines; not to do any work but to get a feel of a real machine.Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com6tag:blogger.com,1999:blog-7445819594773958579.post-5847722663110974472012-04-22T11:19:00.000+08:002012-04-22T11:19:29.001+08:00Lathe Carriage: Oops!I mustered my courage and went ahead to try disassembling all the parts on the apron - the engagement lever, the gears etc. When I'm finally at the real job, I couldn't proceed. The half nut assembly didn't want to come off after I removed the 4 cap screws... Afraid that I may break something if I pushed on, I went on to fiddle around with the carriage gib adjustment which the cap screws and set screws are now accessible. The adjustments were done without the lead screw installed. I managed to get it to the point that the carriage slides easily on the lathe ways with no apparent movement when twisting or lifting it by hands. Some tight spots towards very near to the spindle flange but I don't usually cut that close to the spindle.<br />
<br />
With the lead screw installed, everything changed; there was the sound of the half nut rubbing on the lead screw and the lead screw handwheel was extremely hard to turn! While turning the handwheel from the spindle end to the tailstock end, I can feel my arm getting cramp...<br />
<br />
I inspected the movement of the lead screw with the half nut engaged and disengaged. There seemed an excessive movement of the lead screw which may explained the problem I'm facing. The 3 cap screws holding the apron was released and tightened again with the half nut engaged. This ease off the tightness a little when turning with the handwheel and the rubbing sound is now gone. But the turning of the handwheel is still not smooth. Help!!! It is now worst than before!!!<br />

The adjustment of the gib plate took me a long time. The cap screws beneathe were tighten enough to hold the plate close to the carriage but still allow ease of movement. The apron was then installed to test and further adjusted.</div>

There are some bit of tight spot near the spindle but that's the best I can do with my current skill level...<br />
<br />
The major problem popped up with the lead screw was installed. It was so tight with the half nut engaged that I can't turn the lead screw at all. The 3 cap screws holding the apron to the carriage was loosen, half nut engaged, and tightened again. I did this near the handwheel, in the middle of the way, and near the spindle. Found that doing this nearer the spindle yielded the best result.<br />
<br />
Some slight movement can still be seen on the lead screw when the half nut was engaged. Some grease elbow still needed to turn it. This is not to my satisfaction at all.<br />
<br />
This video was taken to show the lead screw movement when the half nut was engaged.<br />

This time, I managed to remove the carriage which I couldn't previously. This goes to show the more I use the machine, the better I understand it. But my confident stopped right here. I'm deciding if I should disassemble the 1/2 nut for thorough cleaning and maybe attempt some adjustments to make it operates smoothly.<br />

These are the pics taken of the apron and carriage:<br />

<br />
Found some 2BA cap screws yesterday. Poey Huat Hardware has them in steel all along though I was told by one of their staff last week that they only have them in brass. It took the elderly man quite a good 15 minutes to locate the box. Its content covered with rust. He commented that there hasn't been any enquiry on the BA screws for quite a long time. Not very popular in this part of the world. Unfortunately, the plans in those books I bought use them. I'll use the closest metric cap screws when I get started making the tools shown on those plans.<br />
<br />
The cap screws are a little longer than required. That's the only box found so I won't push it. Don't think he is keen to sell me 6 screws having to turn the place upside down - I won't...<br />
<br />
Here is the pic:<br />

There was slight wobbling when the lathe was powered on. I pressed on with the job despite that. The morning session ended when I was at the threading part as I encountered difficulty to start the die cutting. I bought the Proxxon Tailstock Die Holder from Mike and my dearest collected it for me in the afternoon while I was at work at a project called The MeyeRise.<br />

I'm getting excited as I'm coming to an end of this project. Wanted to buy the 2 x 2BA screws but the shop I always frequent only have them in brass. Maybe that will work. Should have buy them to test than merely walking away disappointed.</div>

I've yet to test if the centre lies up with the centre line of the lathe. Feeling exhausted from the long boring showflat duty I was scheduled this afternoon, I decided to stop work, wash up, and do some reading before bed. Got to get up early for Resurrection Day service tomorrow morning. It is the most important day in history of mankind.</div>

Next is to reduce a section down to 5/16" leaving 3/16" length of the stock at 3/4". In order to know which I should stop turning, I tried cutting a groove but parting this material turned out to be rather unpleasant. The AR Warner's part-off tool just jammed mid way through the cut. But what was done provided sufficent visual of the stop point.</div>

<div class="separator" style="clear: both; text-align: left;">
This session stopped prematurely when I cut my right thumb while tapping the arbor. Blood was dripping on the floor and table when I rushed to wash the wound under running water. The pain was terrible. Thank God it was just a cut. Though a little deeper than what I got normally, it is nothing serious. My wife, of course, nagged a little while putting on the plaster for me.</div>

I stopped work at this point as the wound has started bleeding again. I will try to complete this part of the work tomorrow morning before church. Will also attempt to harden it by using my little Proxxon Micro Torch and quenching it in water.<br />

Have a blessed night.<br />

<br />
I finished the arbor with a thread hole to mount the partially completed 1/2 centre and fastened the threaded end of the 1/2 centre in it. This is what I have:<br />
<br />
<div align="center">
<object data="http://www.youtube.com/v/xa0asn7Q06o" height="300" type="application/x-shockwave-flash" width="400"><param name="movie" value="http://www.youtube.com/v/xa0asn7Q06o" />

<br />
It wobble like no tomorrow. I therefore declared this to be good for the scrap bin. <br />
<br />
I do not have another piece of silver steel in my stash bin and thought of using the piece of silver steel meant for the 2 adjustment screws that came with the kit. The 5/8" diameter silver steel rod supplied is slightly longer than 5". Each adjustment screws is only slightly longer than 1". Then it struck me that the extra length is meant to be use to make the arbor... Argghhh... I'll cut a short section of 1.5" to make the 1/2 centre. <br />

I stop work right away, not wanting to carry on till I figure this out. The silver steel was turned with the HSS tool from Proxxon. I tried turning with and without oil, spindle speed of 330 rpm and 660 rpm, advancing the tool 0.1mm to 0.4mm radius, feed slow, fast, and with autofeed. The rough surface remains...<br />
<br />
Anyone can provide me with a solution to this and the reason why this occur? Appreciate any help.<br />

The operation was completed without surprises and I'm happy with the result.<br />
When I got home at night, I cleaned up the threads and parted off the 1/2 centre to length. Next would be to make an abor with a 5/16" BSF tapped hole to hold the partially completed work to turn the 60-degree point, which I'll only be able to continue tomorrow before leaving to church.<br />

The next step is to make an arbor with a 5/16" BSF threaded hole. The job is to be screwed into this hole to have the 60 degree taper cut turned on the opposite end. I went through my bin of steel but couldn't find any suitable size rod for this. What I've is mostly long 1" steel rod which needs to be cut on the bandsaw for use. Its too late to do the work on the bandsaw for fear of angry neighbours pounding on my door and I'm too tired to saw it by hand. I was about to call it a day (or would it be "night"?) when I saw this tap guide I did when I first bought my Sherline lathe. I put it in the collet chuck and started turning it down a little but...<br />

I'm totally wasted... its only 11.10pm and I'm feeling so tired. Time to stop before silly mistakes are made that can hurt myself. Will continue tomorrow, if time allows.<br />

<br />
The model I'm getting is the most basic they have and their least expensive unit I'm willing to break my piggy bank for. The other constraint is on the limited space I have in my home shop.<br />

<br />
The machine, according to the specs given on the website, weighs 85kg, which is a concern to me as I don't know if my work bench can take it in operation. I stood at my shop looking at the bench area and decided to have it on the spot where the Proxxon PD400 is sitting. That's the area with sufficient support beneath the bench for drawers and stuff.<br />
<br />
The dimensions from the front and side are given below:<br />

<tr><td class="tr-caption" style="text-align: center;">From the side. Vertically, I need to allow about 1000mm (or 1 metre) for the Z axis to traverse. Due to the window grill behind my bench, I'll have the handwheel portion of the mill sticking out of the benchtop, which is fine for easier turning of the wheel.</td></tr>

<br />
From the dimensions given above, I realized that I'm hitting the limits of the bench space. This means that I'll have to release the bench space currently occupied by the Sherline 5410. I'm quite reluctant to do that as I'm in the midst of installing the iGaging scales and DROs on it. It is also very convenient for smaller jobs with the available tools and accessories in the shop. Maybe I'll start by giving it some floor space beneath the bench as it is portable enough to be moved. Unless someone can offer me an attractive enough price to take it off me, together with the Horizontal Milling Conversion Base and the iGaging scales & DROs. But... how much is attractive to tempt me to sell? I've no answer. Don't really like to selling my stuff though I've been a salesperson for all my working life so far...<br />
<br />
I'll take that as a good problem, a blessing rather than lack. I thank daddy God for the blessings showering at me despite what I am and what I am not.Wongsterhttp://www.blogger.com/profile/03583616007802325379noreply@blogger.com3
