delta table saw blade out of parallel
Well I have had this Delta contractors table saw for a few years and for the first time I tilted the blade to 45 degrees and When I made a cut the blade burnt the wood. When I reset the blade to 90 degrees it was out of parallel.
Is this characteristic of this saw?
Is it a problem to reset and keep in adjustment?
My email is paul1204@sbcglobal.net – if anyone would email me with some help I would appreciate it.
Thanks,
Paul

This is a very common problem with contractor saws. Shoot dgreen the model# as he requested above, he'll help you out.
Paul,
This is very common with contractor's saws and is a serious design flaw that goes back to the original design of 60 years ago. The misalignment can be corrected by making a fussy and awkward adjustment but will most likely return anytime you tip the blade over again.

John,
Thanks for the input . I had the same thing happen to a grizzly and I never got it back into parellel. I hope I don't have the same problem here. Should I loosen the trunion bolts and leave them loose till I get time to get it into adjustment ??? Or do you think that there is permanent deformation due to a one time event using the force decreasing hand tilt crank. This event really annoys me. I have rods in my back and will need to get someone to help my get it into spec and that may take a while. What would you do?

Paul,The fix is to slightly loosen the rear trunnion bolts and to then tap the thing back in line and retighten the bolts. Typically the blade can be brought back in line by just adjusting the rear trunnion. It will however probably not stay in line if you tilt the blade. The weakness of the design really can't be overcome on these saws which are all nearly exact copies of the flawed original Delta contractor's saw. Only the Ridgid TS 3650 saw, which completely redesigned the mechanics of a contractor's saw, seems to have gotten past the problem.Some of the new hybrid saws are better designed but some are just hiding a contractor's saw mechanism inside of a new cabinet.John W.
John, Thanks for the input , I tried loosining the 2 rear trunion bolts and it wouldn't budge and to get at the front requires bending more than I could yesterday. Hope that something isn't permanently bent. I am thinking of getting someone to loosen all of them and leave it till I can spend the time with help and get it inot parallel. Do you think it is a good idea to loosen them and leave it loose till I can get it adjusted?
Paul
Leaving them loose will allow the blade to shift around as you are making a cut and will almost certainly lead to a kickback or jamming, it doesn't seem like a safe solution.John W.
Oh, I would never use it with the bolts loose
Did you try tapping it instead of just pushing it? Stick a block of wood on the trunnion & tap or rap with a hammer before you go to loosening all 4 bolts. That's per the instructions on my Powermatic.
