Morse Taper Ejector on Clausing Mill

<< < (2/2)

Splat:
Necroposting. Dave, that's a great idea. I need to do this for my Johannson B12 mill, the precursor to the Atlas/Clausing 8520. My spindle top is exactly like yours, but I have a big threaded nut that threads onto that outer 3/4-16 threading. It has a set screw on each side to keep it from spinning off, I guess. How's your ejector tool holding up? Any design changes, etc? Thanks.

My solution was to tap the bore 1/2" X 32 and make a double ended draw bar 10mm X 1.5 , so the head moves less than half the distance of the draw bar , it's still working after 5 years on my MT3 collets .
