I have a similar saw that is even older, but is made the same way.
I am sure you checked but just in case: Have you checked for the thermal
overload switch being popped? It must be reset manually.
Many thianks for the useful suggestions; here's a follow-up from the
- For Salty@dog,com: Sorry to say, but dbp and George are correct -
the mounting posts are integral to the motor housing. This is an
exception to your "motors are mostly universal" statement. Oh, BTW _
it's hard to replace "brushes" in an induction motor....
- For DadiOH - yes I figured ou that Emerson is the OEM - but
requesting parts from Emerson is equivalent to calling GM headquartes
for brake shoes for you Chevy - they want you to talk to their local
dealer. Also - Sears' parts line told me Emerson no longer makes that
motor (or parts for it) - I've got to believe them on this - it was a
custom job for Sears in the first place.
- For <RJ> - I've had the motor completely apart three times now -
removed all the sawdust, etc. Never saw anything that answered to the
description of "start centrifugal switch". FWIW this saw has had
steady use for 22 years, and it's just now quit in this fashion. Just
before it quit entirely I was seeing sparks from inside the motor
housing. Now when I turn the power on, it hums for a few seconds then
blows the (20-amp) breaker.
For Bob F - I've looked on Cragslist and my local want ads - no soap
at the moment, but I'll keep an eye on that channel.
For Charlie Bress- it's not the thermal overload, as it tries to start
(hums & blows breaker)
As for the new saw angle - The low end new saw from Sears is $650 (on
"sale" at the moment for $600) - so if I can get the motor rebuilt for
<$200, I'm $400 ahead. The good saws from Delta & Rockwell just aren't
in my price range at the moment - and this "cheap" one has built most
of my house, cabinetry, several outbuildings, and two rooms' worth of
furniture - so it's working OK for me. But that's my fallback option.
SO - (thanks to Ralph, S. Barker, et al) I've taken the motor to a
local electric motor shop, who've promised to look at it & tell me if
it can be rebuilt. At this point I'm waiting for a phone call.
Meantime (thanks, Jim) I will also repost to rec.woodworking.
Again, thanks to all!
P.S. - I also enjoyed reading the flame war beetween salty and nbp -
it's fun to see two people duke itour over a subject when neither of
then has first-hand knowledge <:-)
