powermatic 66 table saw tilt problem

Have you flipped it over on its top so you can see into the works while you crank it? There will be a bolt with a listing nut to adjust the stoping point. If it's hitting that, obviously screw it in more.

Make sure there isn't something in the front and back arcing groove that the reunion rides in, and lube them with something that doesn't attract dust.

As for the handwheel > shaft > worm-gear, you will be able to see where the problem is by cranking it while you are looking down into it a lot easier than looking up.

Bill I immediately thought about the 45 degree locking screw but figured you had been a wood worker long enough to know better than that. I will be glad to come over next week some time and try to figure it out.

Putting that saw on it's tip would be at least a 2 man operation if it's anywhere near as heavy as my Grizzy cabinet saw but we should be able to figure out something by looking. At the worst may have to remove the top to fix the problem which of course would require some blade alignment after that.

as I study the problem i am now believing that the trunnion on my saw has been tampered with and will not ever engage as it should at the 45 angle

Someone broke into your shop and tampered with the trunnion? Those evil sneaky bastards! The first unisaw I bought came from a metal working shop. It was a bargain, but I had not, nor even seen close to the abuse that machine endured again! The table top had thousands of dings in it from metal dropping on it. The trunnion and just about everything under the table was full of aluminum shavings. And craziest of all was the abuse on the rack and pinion. The pinion was almost worn to a nub. Moral to the story, it can be a nightmare under the table. Vacuum, clean, lube and adjust often!

Thanks for your thoughtful reply; I have not gotten so desperate as to dismantle the saw and turn it upside down as yet may do so if/when i get a new trunnion...

Just make all your joints 60 and 30 degrees and the problem will be solved.

John that is a novel idea if i ever heard of one

I'm thinking.....

Barry Irby

that if the worm will disengage for the gear, something has shifted.

Is the worm welded or forged onto the shaft? If not, is there a set screw that holds it in place? Could the gear have changed it's relationship with the blade/trunnion? I am assuming that when it was built the trunnion and gear had the proper relationship and something has moved.

I don't even want to think about how much labor it is to install a new trunnion.

Here's the parts list *LINK*

Looks to me like everything is adjustable unless the casting is bent.

Bill Gray....is the table saw a 10" or a 12"......there are pictures and product numbers to buy from at Ereplacements.com. A thought....I am thinking that the set screw for the gear part has loosen and needs to be reset. If the shaft has been gouged a little so the screw travels...I would remove the screw and set the saw blade to the positive 45 degrees and redrill the shaft with a small drill....then replace the setscrew with a longer point one on the end....that way the gear will stay at the 45degs. and blade will be always correct.

Just my rambling thoughts......
