Air powered Draw Bolt
Darren:
As an experiment I have tried an air ratchet gun on my mills draw bar whilst at the same time holding it down in an effort to loosen the 3MT taper...
It didn't work, the tool holder stayed stuck fast in the machine. :(
I realise this is not the same as the "proper" tool, but thought it might be worth the experiment.
Just relaying an observation, not meant to be a comment about any other tools out there.... :thumbup:
John Stevenson:
Air ratchet or air impact ?

Darren:
Sorry, it was an impact type...
chalky:
If you have a captive drawbar then unscrewing it with a spanner pushes out the taper. Stuck tapers and bashing on the drawbar are then a thing of the past. Tightening and releasing a captive drawbar, even for a MT3 taper, requires very little torque but does need quite a few turns on the spanner for complete insertion and release of a taper. This can get a bit tedious so I simply use an electric screwdriver to insert and release my taper tooling. Ultra simple powered drawbar! Its usually very easy to convert an existing machine to get a captive drawbar.
Darren:
Sounds interesting, and simple....any chance of a pic or two....I'm not too sure how I could make my nut captive but if i thik hard enough I'm sure I could come up with something....
Ohh, an idea already..... :lol:
