View Full Version : Motor for tablesaw?

Well...I finally got some decent scrap lumber and started building hives and frames. After a few boxes made and several frames made the tablesaw motor has started whining and I fear it needs replacement. It seems that a new motor will cost about as much as what I paid for the saw...as will the cost of a rebuild job. Are there any ideas out there about where one with limited available finances might scroung a used 3hp motor?
Thanks.

Have you considered pulling off the bell ends of the motor and replacing the bearings?

surplus supply (omaha nebraska) has motors for various power tools.

As Walt says pull off the bell ends. If you are uncomfortable going beyond that....... There must me loads of places that can press in bearings (if they are pressed of course) for a lot less than a comprable new motor.

If replacement of the bearing doesn't work, make sure the motor is properly aligned and the fence is square to the blade. If it is contractor saw (motor hangs out the back) make sure the pulleys are lined up too.
Try grizzly.com for cheap replacemnt motors. I upgraded to a 3 hp motor and it made a huge difference. You can take your old motor and put it on your band saw and power it up that way too.
IMO most original equip. is underpowered. But you can cut a lot of wood with a 1 1/2 hp motor IF you have a good blade and everything is aligned properly. Especially the fence.

I have loads of 1/2HP and 3/4HP 1725RPM motors if anyone needs one for small equipment.
Just pay shipping and there yours..... until their gone.

;) Sundance; How do they do with a rheostat, a speed control, I'm thinking for an extractor. ;)

A/C moters aren't happy with variable speed as far as I understand.
There are smaller 1/2HP residential opener motors that are D/C and would respond well to variable speed control by resistance.
They are 6" in diameter or so. Should be enough for smaller extractors up to 30 frames of so (just a guess mind you). They are capacitor start for the initial bump.
I'll check and see if I have extras laying around.

I kept an old Craftsman tablesaw going for close to 30 years .The motor would start binding if it wasnt oiled-so check to see if there are oiling points on it.It recently died so I replaced it with a Harbor Junk I mean Freight motor.So will see how it goes.Make sure its the right rpms and turns the right direction -some can be reverse wired and some cant.
