Motor without start capacitor not generating enough starting torque
Interesting, I'll check to see if it's dual cage and the windings. The cap is 25uf 370v and tested ok with my esr tester so I think it has to be something else, or it was designed this way for pools and spas.- cheeky

Motor without start capacitor not generating enough starting torque
It runs fine when up to full speed and I tested the run cap with an esr tester and it's exactly at the rated capacitance. No tripping breakers or anything like that.- cheeky

Motor without start capacitor not generating enough starting torque
Make sense, it is cost savings, but also purpose built. A little more research shows these motors were popular for pools and spas, so there you go.- cheeky

Motor without start capacitor not generating enough starting torque
Interesting idea, perhaps you could use a momentary switch that engages cap while held down and then switch to pos 2 upon release.- cheeky

Motor without start capacitor not generating enough starting torque
I have a old Century Centurion switchless motor that has a run capacitor, but no start capacitor. It doesn't generate enough starting torque for my application. Sounds like I need a new motor, but I'm curious if there is an advantage to the design and why Century went with that approach? Cheaper?- cheeky

Changing bearings on my bandsaw
Thanks for all the tips. I noticed the tightness of the bearings while trying to balance the wheels (without motor/pulley/belts attached). In the end, I tapped the shaft out and the outer bearings came with it. The other one I just pushed out from the opposite direction. One of the bearings... -

Changing bearings on my bandsaw
Not sure I understand, but there's no housing adjustment point. Pretty simple saw. Here's the relevant diagram for this model: -

Changing bearings on my bandsaw
Good tip about NOS. I had some previous success buying some from an industrial reseller who buys from liquidating companies. Also I'll planning on freezing/heating as appropriate. I think I will put bearings on the housing first and then shaft to see how that works. It's a Harbor Freight copy... -

Changing bearings on my bandsaw
Hi folks, Long time lurker that finally broke down and registered. Hopefully I can give back a little knowledge now and then. Need some advice with my bandsaw, pretty please. Took my lower wheel off my bandsaw to shim, in order to make coplanar with top wheel, and thought it might be good to...
