I am having problems with both shoulders and this causes difficulty-changing tools on the Bridgeport. I have seen but not used the Kurt tooling. I also see the collet type changers. I am not familiar with these but they appear to be changeable without having to lift ones arms very high. Information and your recommendations would be appreciated.

You need to get a CNC machining center with a 40 tool automatic changer. But if that is not in your budget this year, go to Grizzly Tools online, in the search box, type in collet chuck, and there is a possibe solution to your problem. JIM

The “Quick-Change Tooling Systems” are pricey Jim. A fellow over at the PM forum offered me a complete set up with some 20 tool holders for $600 and that was a fair deal going by all the rest of the prices I saw.

Personally if I were you I would call Kurt and talk to 1 of the reps. They have Kurt Draw Bar Kits now and explain to him your needs. They were pretty helpful to me and I’m sure they could put together a kit with the pneumatic switches so as to put the whole thing at your finger tips

The Kurt would be “Brand New” as opposed to a used Quick Change Tooling System and you wouldn’t have to fight over collets on Ebone

Just as basketball discriminates against the short, and sex discriminatres against the old, the fat, and the ugly, football against the wimpy, math against the easily baffled, etc, machine tool operation is hard on the gimpy.

Back in the day woring on the large machine tools, my job was better suited for an orangutang with all the climbing and aawkward reaches, packing heavy stuff, and wrenching 4 ft long chuck keys. I kept pretty fit.

If your shoulders aren't up to handling R8 tooling you are in a fix. If the problem is not being ale to raise your arms above a certain height, I suggest a step stool and a power drawbar. I'd suggest a power drawbar for anyone for that matter. They really smoke the tool changes. You can mount the push-button station at any convenient height.

Time to bring in the occupational therapists for suggestion on how to arrange things to minimize your limitations. I used to work with a guy who had pretty severe tunnel vision so he was put on work requiring narrlowly focused attention. Them OC guys can do wonders with a few simple suggestions glaringly obvious in retrospect but before the suggestion completely invisible.

Actually the Grizzly version of the quick change is under $200. Tool and or collet changing is done at shoulder height or lower which would allow a lot of work to be done with out reaching over head to the drawbar. I am aware that reaching well over head can be hard on arthritic shoulders and other joints too. JIM

If one chose to go with a power drawbar arrangement, I think the HSM magazine had an article not too long back on building a power setup using a very inexpensive Harbor Freight 3/8 impact wrench. Just another thought. JIM

I think bob Warfield site has something on building your own. My buddy bill built one for his mill using a harbor freight butterfly wrench.

Yeah, the power draw bar is a fun project. inexpensive and not too difficult --- what more could a HSM'er want?

There are 2-3 sites that I used as references ... the site that offers the plans (which isnt really needed) -
http://home.insightbb.com/~joevicar3/cheap_drawbar.htm (http://home.insightbb.com/%7Ejoevicar3/cheap_drawbar.htm)

and, as mentioned Bob Warfields site -- I relied on it pretty heavily.
