I'll play with this again when I've time. <br /><br />I received the tailstock extension yesterday. It looks am easy piece to make at home but I'm still not adventurous enough to turn tapers; more so internal ones. Mounted it on the A2Z adjustable tailstock and the problem of the cross slide running into it is no more. I'm really happy with this. <br /><br />Will be work on installing the DRO on the lathe soon, hopefully this coming Saturday (tomorrow). I was scheduled on duty on Sunday full day. <br /><br />Really love your input. Please keep them coming. <br /><br />Regards,<br />WongWongsterhttps://www.blogger.com/profile/03583616007802325379noreply@blogger.comtag:blogger.com,1999:blog-7445819594773958579.post-39030475480902359612011-07-24T11:41:36.329+08:002011-07-24T11:41:36.329+08:00Wong, on the center I'm not sure if you were a...Wong, on the center I'm not sure if you were able to actually get it hard. Did you test with a file? Press a fine file on it and try to move it. If it 'bites' in and starts to file off material it not hard. When properly hardened the file will slide over the part and not cut, they call this 'glass hard'. Then it will need to be annealed at a lower temperature to soften but not too much.<br />When you have trouble getting the part hot enough just put it on a cooking burner first to pre-heat and then use the torch to get it hotter before quenching. Also get a bigger Metal container for your quench can. Plastic can melt and spill the water, and if you are using oil it would really be a mess.<br />GeneKAnonymousnoreply@blogger.com
