I was surfin' through Cl last night and came across an add for a shop smith mark V for $50.
that caught my attention:thinking:
i clicked the link and sure enough a dust dirty mark 5 "greenie" as they are referred to.
they were manufactured from 1954-1960 in this configuration.
apparently all models can share parts and accessories with ease.
i called the seller and he professed it did'n't run and hasn't run in a long time.
this is right up my alley...:nuts:
i removed the 3/4 hp 115vac drive motor, it is attached to the rear lower motor shield.
the shield is screwed to the head casting.
the wiring is super simple. it has a DPDT on/off switch, a grounded power cord.
a 225 UF start capacitor, the motor has a centrifugal switch inside for start cap.
i replaced the factory DPDT with a 15a DPDT switch, replaced all the wiring spade connectors.
i bench tested the motor. it fired right off no hesitation and sounded good!!!
i did a little homework on the shopsmith and also realized the v belt was bound up inside the headstock.
after a few taps on the headstock, a whole almond, shell and all ,fell out of the v belt pulley.
it freed up the infinite variable drive system and the pullies were able to turn free again!!!!hew:
i reset the infinite variable drive to the slowest speed, an operation that is easiest done while the transmission is in operation, but can be done with a little patience ,stationary.
i replaced the wiring and remounted the drive motor.
i plugged her in and hit the switch, she fired right off and came back to life.
i ran her at low speed figuring if there was going to be a bearing failure i'd like to control the collateral damage.i kinda created make shift scatter shield .i draped my welding leathers a over the headstock and tied them off with a couple band clamps to prevent movement. i fired the motor back up and slowly cranked the dial and took her up to full speed, somewhere above
5,000 rpm and held her there for about 2 minutes or so.
she didn't really like going that fast, the old bearings started to develop a howl.
i cut the experimentation short, knowing the bearings need replacement.
i'll do the bearing replacement in another thread, complete with pictures and descriptions for those interested.
I welcome comments,questions and stories
thanks for looking!
