    I don't know about breaking down doors to get a machine inside, but I do know one thing. Do not put machines down the basement. Trust me... if you do, one day you will be very sorry.

    With your air only idea, you might be barking up the wrong tree without a paddle, or something like that. It could work for a basic test of the brake mechanism, but operationally I think air alone is...

    You sure you don't mean 230V? Didn't think 240 was a thing. Could be wrong.

    There are already adjustable torque control tap holders that have been around for many years. I think they handle most if not all of the problem(s) you're trying to solve for.

    Yes-yes... all of the above. Just 2nd-ing these suggestions. And 3rd-ing the fist suggestion that you must accurately measure hole size. Otherwise it's a crap shoot.

    Yes, like he said. I'd also pay attention to the P6 accuracy class. Also listed sometimes as ABEC 3. I'd say standard for a machine tool gear box. They're not spindle bearings, but held to closer...
