Air powered Draw Bolt
Darren:
Not sure there Bernd, I don't do it very tight as it is. Once I had to re-tighten due to vibration, just nipped it up a tad further.
I believe this is just am MT thing....or at least they are the biggest offenders.
Stilldrillin:
I insert my MT3 mill tools, as I would any MT taper tool, then nip up the drawbar finger tight, just to keep it from falling out. ::)
IF it slips under load, (very rare), I nip it gently with a small spanner.
Never had any drive problems, and only a gentle clunk from a small lead tup loosens the assembly..... :thumbup:

At least on mine, the downward pressure results from the impact wrench turning the drawbar which is screwed into the R8 collet. The impact itself imparts torque that helps to break the taper.

What do you have on yours? Home made or commercial? Briggy init?
Any chance of a pic....

Mine is a clone (apparently) of the Kurt unit.
