All,
I have been sending post after post (at least it feels like that) over the last few months regarding my search for a new table saw. I wanted to state that I appreciate all of the feedback that I have received. I am still on the search, but believe I have found what I want.
Seller on CL has a mid 90's unisaw (S/N 01F38218 CAT Number 34-806) that has a 5HP motor and seems in really great shape, but it is three phase. Seller has no way to start the saw in it's current condition. I looked the saw over, checked for square on the blade with my drafting square (but not runout obviously) and look all over the inside of the cabinet. No cracks or damage. Tilt works smoothly, but can be improved with some lubrication. I was thinking it would be easier to install a new single phase 5 HP or 3 HP motor.
1) What would be the value of a used 5hp 3ph motor?
2) Motor in the saw runs at 4000 rpm. Would a single phase 5hp motor at 3450 rpm be the best replacement? I know I would lose something, but it couldn't be too much.
3) I have looked on the bay for a new motor. Are there any other places to try? Again, I would like a really nice (if not new) replacement motor
4) What kind of effort is involved with swapping the motor? I would try some of the other solutions, but I think the motor swap would be easiest, and would retain most of the original power.
5) What would you do to protect yourself by purchasing a saw that doesn't run under current power? I was thinking of writing something in the receipt, however, I know it's "buyer beware.
Seller will take $500 for the saw if I bring a new motor. I think it is a SMOKING deal, but not being very mechanical, I want to make sure I can easily swap out the motors.
Thanks,
Dwain
