When I tilt the table saw blade, the blade goes cockeyed. It seems to me that the weight of the motor keeps the back half lower than the front half. So, I can get the right angle cut but the board would no longer be square after the cut. This is on a 50’s Craftsman saw. I hope you can envision what I’m trying to say. Is there a fix for this?

I’ve heard of this before. I believe on rigid saws. Someone here can correct me if I’m wrong. Can you post a picture of the underside of the table to determine how the motor is mounted. It might help diagnose the problem. It sounds like poor machining on the moving parts. As you tilt the motor and blade assembly it gets further and further out of square. Without a picture though you’re probably going to have a hard time getting a fix for it. Sorry I couldn’t offer more help

Most of the time when you see this on contractor’s style saws, it’s because the trunion bars are not coplanar. See the link in this post from ForstGrl and I think it’ll probably get you on the right track. Good luck!

HokieKen – Although I should be claiming victory, according to the article, I will give this a try and report back. Thank you for the link.

The article doesn’t mention it, but you should check to be sure the front and rear trunions are parallel as well as in-plane. Normally though, if they aren’t parallel, it will be hard to turn the wheel to tilt because as it tilts it will start to bind. A simple check is to loosen one of the rear trunnion bolts and crank the blade to 45 deg. If you see the loose side of the trunnion shift as you tilt, it’s an indicator that there’s some misalignment.
