This morning I setup the top plate in the vise, and set the DRO to the center of the plate. Then I drilled & bored the four .5000" dia. corner holes .
Next I made a test run of .002" deep on the top of the plate, figuring that an error in my numbers would easily be removed by resurfacing the plate! When satisfied that my setup & numbers were good, I proceeded to mill all the pockets. The plate was sitting .015" off the top of the vise, so I had to use extra care not to mill into the cast iron vise!
With the next set of numbers, I milled all the webs thinner, finishing the large milling operation on this part!
While I was working, the UPS guy dropped off all my ordered parts and cutters, so now I can finish milling the larger radius on the edges of the bottom plate! All that needs to be done to the bottom plate is making a little counter bore in the center, so the bulls-eye level can be mounted.
The little adjustable feet arrived as well, they need to have a .125" radius turned on the ends of the screws, to add a little softness to the protruding screw! That will be done in the lathe with a little fixture and a radius tool!
Enough for one day!
