How do I repair the tilt on my artisan table saw ?


I'm not familiar with your saw, but I'm familiar with table saws in general.
The tilting is achieved by a worm screw on the end of the crank handle engaging a partial worm gear on the tilt mechanism.
If all you get is clicking, the worm is jumping out of the teeth on the worm gear. It's likely that the shaft you're turning has slid a bit in its bearing and the far end of the worm is no longer constrained and no longer holds the worm tightly against the worm gear.
I'd say just take the whole thing apart and re-assemble it. In the process, you'll find out how the worm has slipped out of place and you'll see how to put it back where it belongs so that the worm is supported on both ends.

Difficulty raising and lowering the blade on Delta rockwell10" unisaw 34-450


Ok, basic question...is the lock engaged? It is the small knob at the center of the adjustment wheel. Is it possible the screw has been galled?

Lost ability to raise the blade for operation.


Most often this is caused by the handle or wheel that is used to raise/lower the blade coming loose on the shaft that operates the worm gear in the trunnion. There is frequently an allen set screw that locks this wheel onto the shaft and this set screw comes loose or is lost. If loose, simply tighten it.
Otherwise, it may be time for some routine maintenance. Unplug the saw, clean all sawdust and debris from under the saw using compressed air if possible, and then lubricate the worm gear/gear box and trunnion ways. Some people prefer silicone for this, some use WD40. I prefer normal motor oil. In any event you will need a long oil spout to direct the lubricant into the worm gear and gears, then/while raising and lowering the saw. Also lubricate the angle adjustment gears.
If you keep your saw properly lubricated, it will function easily and be a joy to adjust. Otherwise, it can become a struggle or just impossible.
Good luck.

My powermatic table saw is very hard to raise and lower the blade and i have removed the knob that tightens the handle so the blade does not move and its still very difficult to move the blade


You need to do some maintenance on your saw. First unplug it. Then blow out the sawdust from inside the saw, especially around the trunnion ways and gears and worm gears that engage them to raise/lower and tilt the saw. Use a good quality lubricant to lube these worm gears and the shafts and pivot points. I use motor oil, have for years, and find it does a better job and lasts longer than any kind of grease or silicone. Use an oil can with a long spout so you can direct the oil where needed, then move the saw up/down or right/left to work the oil into the worm gear and mechanism. In a pinch WD40 is fine, though it won't last as long. Periodic re oiling will maintain the mechanism in peak condition, and the drops of oil you spill in the process won't do any damage to your so. No, it won't get gummed up with sawdust. Try it, you'll like it.

HI, Just bought an older Craftsman 10 inch table saw, model 113.299040. Still puzzled by the difficulty of raising the blade. Turned saw over and was able to wire brush worm gear and matching cog pretty...


I have the same model, same problem too. I was able to get the adjustment better by a light greasing of the worm gear, I took this one step farther and made a cover for the worm gear shaft so it doesn't always get loaded with sawdust, ( i cut a solid dryer vent pipe in half and placed it over the worm gear , seems to help a lot, once cut I wrapped it in a round placement and just zip tied it in place

I have cleaned the worm and Gear segment for blade raising mechanism on my 66 and it still binds and is stiff. What do I do next?


Try lubricating with silicone spray. I use it for just such things, and I'm happy with how it works. Also, clean and lubricate the lock on the elevation control.

I can no longer raise or lower the blade on my 10" sears table saw' model # 113.298032.


After some use the threads on the raising mechanism can become clogged with sawdust and resin.
UNPLUG the saw and look underneath up inside the box. there is a rod that runs from the wheel you turn to raise and lower the blade into the actual mechanism. Brush it clean and give it a good douse of WD40 to help clean it. That rod must turn freely so look for any obstructions that will prevent that from happening
