  • Bridgeport Powerfeed Full Of *&$%! And Fail...

    Ok I have emailed the Boss about getting pictures so we can identify it better... it's a Bridgeport with a Bridgeport powerfeed. I pull the lever to move the table and sometimes it glides like a (insert crude metaphor here) other times it grinds and stutters and makes unholy noises and jumps about like a (insert humorus and improbable metaphor here.

    In general where should I start looking? Gearbox? Motor? Lever arrangment?

    if its the old heavy manual gearbox type

    then you shoiuld be looking at the bottom bearings ..

    needs a good clean out or replacement bearings

    it could also be the shear pin underneth the right hand side of the table ..coming out ..or its ready to break off that trusty rusty bent nail that replaced it the last time it bust.

      It has an on-off switch and a knob for controlling speed and a "rapid" button.

      Sorry, should have mentioned that in the OP.

            Trying to remember real hard. Had the same problem, had to replace (make) a bushing for the control lever in the gear box. It became so sloppy that it would not fall into the detents for the left-neutral-right feed properly (a confused transmission). Cured the problem but still sometimes if I’m not positive on my shift the motor still hums but no movement.

            When you take it apart it will become quite obvious, that part I remember. There was something else about the gear oil leaking but that was obvious as well and hasn't leaked since.

            must be getting old

            Cheers, Bob

              Bob:

              Even "old" you still know more than I do on the subject. Hopefully your hints + AE's hints will yield results.

                  Been a long time since i was in one . But not real fancy in side . Take apart and look should be easy enough to figure out what is not working right .
                  Their are a few bushings that could be wore and the teeth on the directional gear shifter .

                      It sounds like you have a 6F or 8F


                      Real bad jumpy stuff -I has one -the comutator segments were loose on the armature.. Toast... Found another motor on Ebay...


                      Check your brushes. Check that oil hasn't filled the bottom of the motor.
