The New Machine

[Jonathan]

Hmm, that's nice but could be a problem long term as you wont notice if the thread or something starts seizing up. The impact driver will probably just keep going and potentially cause excessive wear / break something? Just a thought..
How long until automatic tool changing then?

i think it works well

now you need to mount it on the machine and have a foot switch.

i don't see it as going to be a problem as the drawbar is the soft expendable part. As the tapers and threads are hardened steel.

There are quite a few impact gun drawbar designs kicking around, and I've never seen anybody mention having any major problems with them.

Biggest issue with using an impact gun, is getting a consistent torque.

Also, don't rely on the threads in the taper shanks being hard enough not to be damaged by a soft drawbar. I bet if you tried filing them, they'll file down without that much effort.
