how many HP can a 5HP horse, if 5HP can horse
WOW, the last time i visited was back in March! hope you guys all got a lot completed over the summer (i see Thrud almost got himself "completed", but sounds like he's doing better).
i put in a 22'x32' polebarn, finished my JD 40U (even got to rebuild the hydraulic pump twice), started tearing apart the Farmall F-14, cut down about 50 trees, dragged home a bunch of other crazy machines, finished a bunch of woodworking creations for my parents, rebuilt half of an Oliver OC-46, cleaned out the garage/shop enough to actually use it as a garage AND a shop, and even had time to get my Rotary Phase Converter built and mounted on a dolly.
which brings me to my question (eventually). now that winter is approaching and my outdoor projects are about finished for the year, i'm working on getting my collection of old metalworking machines running. my RPC uses a 5HP 1725 RPM compressor motor. i have it fairly well balanced and the baby fires up in about 1/10 of a second. i've used it to run a 1.5 HP motor on a tablesaw, a 2HP motor on a woodworking shaper, and a 1.5 HP motor on my latest find, a Delta 31-730 belt/disc sander. all these machines fire right up with the RPC. my next goal is to get the beast of a G&E metal shaper running. it has a 5HP Diehl motor. i was cleaning it tonight and the motor assembly tag is still on it. it was built in April of 1939!!!! anyways, it doesn't want to start spinning (turns about 15-30 degrees and stalls). the shaper was being used up until it was hauled out of the old shop and auctioned, so the motor should run, but it has been in my garage since the beginning of the year. it is a little tight to turn (doesn't just spin freely like the motor on the RPC). i pulled the belts off of it, so the only thing it needs to turn is itself. the bushings show no signs of rust, so i'm guessing it just needs to get spinning a few times to get the bushings relubed, and it should run fine.
finally, my questions. any tips to loosen the motor up? will my 5HP RPC get this baby spinning? if not, i heard if i would fire up say the 2HP shaper and then try to start the 5HP shaper, the extra 2HP motor will allow me to get the 5HP started. i was thinking of maybe wiring the 5HP Diehl motor into the RPC (and disconnect the present 5HP motor) and see if i can directly start the 5HP Diehl motor with my capacitor network in the RPC. any thoughts on if this will work (and if it is a good idea)? my setup is wired to handle 30 Amps, so i should be within tolerances for getting all this stuff running (i think). if not, i can bump everything up to the 50 Amp limit on the outlet.
thanks for any words of wisdom, and i hope to be back on regularly now that the "indoor projects season" is upon me.
