Decided to set up my Burke #4 as a vertical milling machine today. After inspecting the universal head, I can’t figure out what the spindle size is for collets to hold end mills. OR, if some parts are missing... bought the machine at an estate sale, disassembled last year. So nobody to ask locally.

The unit looks like it will take some sort of collet and draw bar assembly to hold end mills. But the major and minor ID don’t match any B&S or MT dimension chart that I looked at. (Looks like the drive arbor is size B&S 9)

Anybody recognize what I have here, and what I need to hold the end mills??

It takes 3c collects and a draw bar. At least mine does.

Yes, it uses 3C collets and a drawbar. I made the drawbar for mine and posted a print to make on here somewhere a few years ago. It is easy to make.

Mark and Gregg, thanks! Yikes, now all I have to do is find more unobtainium.

Well, that was easy. Ordered three off eBay.
