Quick Change Tooling

I missed most of this thread, so excuse my repeats.
Most of the power drawbar retrofits are nothing more than an impact
wrench mounted to the top of the machine with a spring to disengage the
socket. Real quick change spindles do not operate on the same principal
as the R8
Other "quick change" are collet adapters with R8 shanks. They are
quick because you don't have to mess with the drawbar once they are
installed. But you do have to have a spindle break and use their wrench
and collets.
