Ok, seems I’m getting somewhere. I removed the nut from the spindle and out dropped a 9/16 “ collet. So looks to me like I don’t need to do anything except buy enough collets to fit the end mills that I buy. I assume the 30 B & S taper is what the universal fixture has so I don’t need B & S taper end mills, correct. I looked on eBay and found them for about 15 each or less. So , where is the best place to buy these, what sizes should I get and where is the best place to get get good end mills that aren’t china junk? Thanks for all the help guys.

Oh. I can’t tell for sure but I bet the motor for the table feed is 3 phase as well. The ID plate has been painted over but I found one spot I could read and it said the motor was 220/440 volt. So that means I’d have to have two VFDs to make it work.
