Chris, an R8 does not NEED a driving peg, it is there as a convenience to stop the collet moving whilst pulling it in. Believe you me, if you really pull on the drawbar, an R8 will be quite difficult to drive out. I use an air powered drawbar and can control the torque.  I also use an Autolock in the R8 ended Quill!

Don't worry. We're on the same song sheet. My vertical milling machine is an R8. I generally loosen the drawbar a  turn or two and then tap it with a hide mallet to release the collet. It certainly won't fall out and that's after tightening it only modestly in the first place with a ring spanner and holding the driving belt.

What are all you old women on about - Julian got the taper out 2 pages ago - and there was no mention of R8's it was Morse #3 taper! -
 
Move along now - nothing more of use here!

Actually the discussion was broadened to the nature of collets generally but I'm happy to discuss the very specfic nature of one size of morse taper collet... if that's OK?
