Re: Bridgeport quick change tooling

Thanks for the info Jon. Your story about not selling the pull studs
fills in the picture for me, i was wondering if those studs screwed
in or if they were intergal to the holder. I downloaded the 34 page
manual at the Acu-Rite web site, was supprised at the amount of work
it took to install. Learned a lot from reading it. Also looked at
the other systems mentioned by others in this forum like snap. These
products are greatly overpriced. I am now thinking of making my own
system.
