That's the beauty of this forms there is very wide range of skill sets and knowledge.
We all start somewhere. And we all have made some mistakes along the way and if someone says there perfect I would be skeptical lol.

I thought one uses a wedge key to dislodge MT tapers on a mill. @David_R8 you had a MT spindle mill?
Wedges are used when there's no drawbar like on a drill press.
Did your mill have a drawbar?
Sure did. It also had slots in the spindle to use wedges on a drill chuck arbor.
Did you not use the wedge to dislodge MT collets as well?

So how do you get the tool holders out of the spindle?
So what do you need this 'thumper' for?
You undo the drawbar a few threads and then hit the top of it with a hammer (or in my case a plastic sledge). Same as R8 but a bit more stubborn.
See my last post
Ok, I get it now. He needs heavier mallet/hammer....
Yes, but no. Doesn't really need to be heavier. My plastic mallet works better than my brass one. It's all in the quality of the "thump"..... LOL!
No as they were on a drawbar. Loosen a few threads and give it a whack, presto.
There is probably a recommended torque rating out there but I try not to over tighten. It can suck the collet or arbor in tighter than it really needs to be, which just makes it difficult to remove. Bang-Bang removal is probably not great for the threads or the bearings. So tight enough so tool wont spin or loosen & just a teensy bit more. The way I stumbled onto this was occasional hand tightening & forgot to wrench obviously not paying attention. But I'm sure if it was heavier cutting I may not have gotten off as easy. My spindle is R8 so might be a bit different to MT. I use a Milwaukee cordless driver & socket on my drawbar, more as a reach convenience, but another plus is you can set the clutch torque & be somewhat consistent.
