Re: Is 1/2 HP really enough?
开云体育Nice looking 10K! Mine came with a brand new 1 HP motor (it had been 3 phase) and it really struggles to make a 20 thou cut too. But the problem is in the flat belt, not the power of the motor. When it bogs down it just throws the belt off the pulleys. Does your motor stall on heavy cuts or is one of the belts slipping? The 1966 SB catalog that I have seen lists all the motor options as being 1/2 HP. Lots of factors can affect depth of cut ability. Material, cutter, RPM of work and feed rate. A flat belt upgrade is on my to do list. I know that all the power available is not being transferred to the spindle. In the mean time when hogging off material, I find the fastest removal rate that works by experimenting and then just accepting the extra turning time. It's all enjoyable to me and way better than when I didn't have a lathe... Turning scrap parts into pounds of chips and killing cutters if half the fun!

New to the group, just picked up my first SB (1952 10K) which came with a 1/2 HP Westinghouse motor. Not sure but motor at least looks original. Anyone know what these machines came with new? Poor thing is struggling to take even a 20 though cut. Is it possible that something is keeping it from making full power? Start cap starts it right up, but not sure if the run cap could possibly be causing a problem. Any help would be appreciated. Machine was in pieces when I found it a few days ago, here' |
