I have a 1944 Delta jointer (model 37-207). It currently has a 3/4 hp motor on it and runs ok, but the old motor is a little loud. I also have a spare, more quiet, 1.0 hp motor that I could put on the jointer. The jointer is all cast iron and very heavy. The original instruction manual only states that any 1/3 hp motor can be used with it, that it should be 1725 rpm, and the cutter should run at 4200 rpm. I have seen online other vintage Delta jointers that had 1 hp motors on it. Would there be a noticable difference/improvement should I install the 1 hp (1725rpm) motor, or would I be risking damage to the jointer? Any helpful feedback from you guys would be appreciated :-)

3/4 hp and 1 hp ratings are pretty close. I wouldn’t expect to see an increase in performance.

If the 1hp motor is the same frame/mount, speed, direction and shaft size then it could be swapped… but I doubt you will see any real improvement. And if the 3/4hp motor is original to the machine, it would decrease the machines value if you swapped it out with a non-original one. I’d be more inclined to figure out why the motor is making noise. Probably only needs a couple bucks worth of bearings – which is an easy, inexpensive fix.

Thanks. The motor is an old Craftsman motor where there is a shaft on each end. I am guessing it was from one of those old Craftsman 8” table saw/jointwr combos. So, it’s not the original, I am guessing, but it’s definitely vintage.

Have your say...
