bc.gold 3,406 #1 Posted October 29, 2021 Putting JB weld to the test, this table saw arbor had a seized bearing that damaged the arbor. Share this post Link to post Share on other sites
pacer 3,177 #2 Posted October 29, 2021 Prolly work.... stuff is pretty dern good! But there IS one critical point to success.... and that is CLEANLINESS!! Hospital clean! Get some Acetone, or equivalent and maybe a scotch pad and clean that sucker really good . I recently had a bearing plate on a big twin break and trying to get the seal out I booggered the crank a tad and I JB'd it, was late in mowing season but I did get in 3 cuttings - at about 3hrs each - and no sign of leakage yet. 1 Share this post Link to post Share on other sites
Skwerl58 763 #3 Posted October 30, 2021 I just put some JB Weld in a hole on my muffler on my 414-8. Sanded it and wiped down, worked it in the hole and spread a little wider than the hole. Going to paint the muffler and hopefully it want be a projectile when I fire it up. 1 Share this post Link to post Share on other sites

lynnmor 7,814 #5 Posted October 30, 2021 If you are concerned about that dark band it may be only slightly worn. If that is the case, Locktite 609 would be a better product. Share this post Link to post Share on other sites

The dark band is JB Weld after curing and being machined back to spec, after reassembly did some test cuts then tested for squareness the old saw cuts true. PO had installed casters which brought the table to an uncomfortable working height so I removed them. Share this post Link to post Share on other sites

No one nearby has the equipment to properly weld the shaft, once again I put my faith in the JB Weld metal repair epoxy.

The JB Weld metal epoxy was used to fill a 0.010 gap once cured was machined back to spec, the roller bearing is now firmly seated on the arbor. 1 Share this post Link to post Share on other sites
