My other thread was not very specific but I did make it through the backplate fab and assembly. I really didnt want to mess up the attach holes so I went as methodical as I could. Latheman helped me with an old back he had that was pre threaded 2 3/8-6 but the hole pattern was not right. I faced the part and reduced the OD so it would fit in the recess on the chuck.
Layed out the holes and some witness marks this helped since my eyes are getting old.
I wasn't sure how to approach the hole but I did some searching in here and I saw that at least one guy goes straight to full size so I did too.
I am using an early 70's Rockwell 11" drill press that I refurbished but havent used a lot. It did great!
I didn't see a bottom tap in my box at first glance so I ran the depth a little farther down than needed. This is one of the things that will bug me everytime I look at this part!
