|Moving over to the start. The more I use the mill, the more confident I get in getting to the spot I want using the handwheels. The right limit of the slot was set with the tool maker's clamp on the right of the job against the saddle.|
|Moving to the left limit and setting the clamp.|
|Milling the 1/4" slot with the Sherline 1/4" slot drill. The Sherline's endmill holder in use here.|
|The 10mm slot drill in the ER16 collet chuck was employed to cut the counterbore slot. To set the depth, I plunge the slot drill to the depth of 1/4" and fit another piece of the toolmaker's clamp on the column bed.|
|Slot done. I went at 0.25mm per pass to minimise vibration. The cap screw sit flush with the top surface of the Base.|
|The centre hole enlarged to 6.4mm to tap 5/16" BSF.|
|Testing fit. No side wobbling encountered. I'm pretty pleased :)|
The instruction calls for the 2 x 2BA holes to be done on the drill press. I was running out of time to set up the drill press (its under the bench...) and so stand the part in the vise and carry on.
|Locating the side and dialed to the centre of the workpiece.|
|Centre drill and drill through with a 4mm. I'm at the limit of the z travel...|
|A piece of card stock used at the back to check if I'm right in the middle. Not too bad..|
The part was then flipped over to drill and tap the other 2BA hole on the other side. This completes the work on the Base.
|View from the back where the 2MT Arbor will be screwed in from.|
|The front. I'm wondering if the screws are a little too long. The drawing shows them as almost flushed with the surface. Can those who did this confirm if I need to shorten the screws?|
The rest of the work will be mostly done in the lathe. From the plan, I'm left with making the 2 adjustment screws, the Centre, and the 2MT Arbor.
I'm hoping to get back to the shop real soon!
Blessings to ALL!!!
