I have just acquired a mid seventies Sears table saw. In overall good shape, but the trunnion is not working properly.

The angle adjustment is incredibly stiff. It will not move beyond one or two degrees from vertical.

Any suggestions on where to start looking will be appreciated.

Thanks!

I just got done taking apart a similar saw. The trunions hold the whole saw in place with a friction fit. It just rides metal on metal. I would suggest cleaning it out and lubing it. I think people like to use that dry silicone lubricant so dust won’t stick to it like regular grease would.

+1 for Joshua’s suggestion.

You could also use the new product from WD-40, spray White Lithium Grease, available at Lowe’s Home Depot and most large Hardware stores.

Just to make sure, did you loosen the lock handle on the front of the saw?

+1 on Mike’s suggestion. On the front of the saw above the height adjustment is a locking knob. That’s for the bevel adjustment. Make sure it is loosened.

I would avoid using silicone. I’ve seen a few finishing nightmares that were presumably caused by tiny amounts of stray silicone. I have had good luck with paraffin or candle wax. I rub or melt it onto the threads, teeth and trunnions and it lasts a good while. -Jack

Jack, that’s really interesting. How often do you re apply?

I just went through this. Don’t try turning it to hard or the whole top base may bend. Take it apart and clean it and remove all traces of grease. I then coated everything with Johnson’s wax and then applied Dupont Multi-use lubricant to trunnions and gears. That stuff is like a wax with Teflon in it.

On my Craftsman saw there is also a spring loaded screw in the rear trunnions. This might also be set to tight. In any case a complete disassembly is not out of order on a new purchase.

Thanks for all the help. Cleaned strange looking crud and sawdust of screw, lubed, and now works like a charm. Good suggestions about the front lock and rear screw, both were ok.

Joshua, I haven’t yet. It’s been over 3 years – still operates smoothly. There is sawdust is built up inside but not sticking to the teeth. On another saw I mixed paraffin with mineral spirits over hot water and brushed it on. That was a PITA so I “borrowed” some candles on my newer saw and dripped it on. I had the saws apart/upside down when I did it. If I had better dust collection and maybe compressed air to clean it out more often I would probably use white lithium grease. -Jack
