I recently found a topic on a different subject that may go along with this

"decommissioned" or not but the following was my response to something that
may follow along with this particular "Old Craftsman Table Saw-Motor Problem"
discussion. (If you know of another thread in Home Owners Hub" that could
benefit from my comments, would you please forward this along to it)?
I know this topic was discussed over 13 years ago, but if anyone ever reads
this far down in the responses, I would add a big WOW to the comments about
increasing the motor pulley diameter!! If you are positive that the pulleys
are the original and have never been messed with, buy the same dia pulleys as
those!! By increasing the motor pulley dia from your original 2.5"(?) inch dia
w/o a corresponding arbor dia, it's likely your motor won't stand the
additional amp draw!! If the manufacturer tested and approved the original
set-up, I would certainly not vary much or at all from those pulleys!! You
would be increasing the work force the motor has to deal with by a factor of
2. What does this mean, very short motor life/poping that 15 amp circuit
breaker every time you feed a board into the blade! Check it out, but the
increasing of the motor pulley diameter to be twice that of the arbor pulley
is just asking for the cost of a new motor and a lot of frustration!!!


Pray tell...

Why are you talking about motor pulley sizes in a thread about dirty
switches?

"I would add a big WOW to the comments about increasing the motor

No one mentioned pulleys until you came along.
