Topic tags/keywords: question tablesaw bearing

I replaced the bearings in my old craftsman Tsaw, threw it back together and now the blade has a bad wobble in it. Pulling it apart again I discover the old bearing had frozen at some point and spun in the seat, it’s part of the casting. I’ll first try to shim and locktite it. If that doesn’t work I’ll probably try to fill in the groove with metal/epoxy putty and scrape it to size. This part is too big for my little 6” swing lathe and I don’t have a Bridgeport which would make the job easy. I was wondering if anyone here had tried the metal fill putty and if so had they any suggestions/tips.


PS: Most especially could I lay a bead of putty then press the bearing in and let it set?
Would grease keep the putty from bonding to the bearing?
Thanks again.

I repaired a motorcycle rear wheel bearing race years ago with epoxy – JB weld I think. Coat the outside of the bearing with paste wax, fill around the race with epoxy, put some epoxy on the brg od, put in place with the shaft through it to align the brg, let cure, see what you have. If the brg wobbles much when placed in position, dont use the wax. The adhesion to the brg od will be needed to hold it in. It may end up a permanent bearing. I probably put 40k mi on that bearing before I crashed the bike and ended the “test”. It was a heavy sport touring bike.

Hi Mike:

I’ve never tried that. Those old craftsman saws are plentiful and cheap on Craigslist, yard sales etc.. Maybe you can buy a second one for parts.

regards, Kerry
