Got out in the shop for few hours today. i got the lower support plate drilled and c'bored and the punch die drilled and tapped. Surprisingly the two pieces bolted together so i must have done something right...
Drilling the base plate with guide holes. There are six of these that will be drilled out to .343 and then c'bored for a 5/16 SHCS

One more to drill and it's ready for c'boring.

C'boring.

At least all of the screws fit...
