I have a Delta Unisaw that I had for over 30 years, now the blade won’t say tight. Any ideas ?
Thanks

First idea: give us a bit more to go on. “The blade won’t stay tight” doesn’t give us a lot to work with.

Ok, I put the blade on the table saw arbor and tighten the nut up, as I’m cutting the blade loosen up.

Threads on the arbor could wearing out or the nut that holds the blade flush to the flange could be wearing out. I’d go with the latter first.

Is it possible the saw is running backwards ? Maybe a bad start capacitor

Check your arbor flange/threads for crap… most likely you are not getting the blade fully seated initially. Truing up the flange and washer may help (see here). There really is no other way for it to ‘loosen’ up as the direction of spin causes the nut to tighten, not loosen.

Cheers,
