Sidney Feet, first 4 jaw use, first taper cut.

Aluminum was cast into canned tomato cans to create billets.  This is fairly standard fair and needs no further explanation. 

The billets were turned round and a depression cut into the bottom.  

With the outside jaws interfered and I could not reach far enough to cut the tapered sides.  The 4 jaw chuck with the jaws in the inside configuration did.  the carriage was locked down.  The compound was used to move the bit along the work and the cross slide to move it in and out.



The taper was cut using a tool with additional top rake which resulted in a much smoother cut.  Still not great but best yet.   Need to try finishing with a rounded tool with top rake.  The taper was sanded with course, medium and fine emery cloth.  Then sanded with 320, 400, and 600 wet and dry.

I will have to mount the feet between centers if I want to cleanup and polish the lower section.  I  Then I will have to put it back in a chuck to drill the top to create the cavity for the bolts sticking through the lathe legs .
