Question about Delta 17-950L 16-1/2 Crosshair Laser Drill Press 17-950L

1 Answer

Unable to easily raise/lower table.

Over time the table adjusting (up/down) handle to the worm gear is becoming harder to turn. Does crud get into the gear over time? Assume that I need to take the head off, remove the table bracket and clean it out. Before I do all this, is this a correct assumption or is there an easier solution?

How do I fix the drill press table so it moves up or down


most tables have a rack and pinion gear that raises and lowers them , if this is tight first ck that lock bolt has not been applied (next to crank handle) if ok then oil it , me i use parafin wax because i only use mine for wood and oil tends to stick the sawdust to it , so i use wax instead

I can't raise my table saw blade when I crank the handle


My DeWalt Table saw does this,and for me its cleaning with a air compressor and nozzle. I cand seem to prevent it though. I tried grease on time and it just plugged up faster. I want to try a gravite lube next. To me it seems to be a desiegn flaw and I just clean the spline thead shaft that lowers and raises the blade. So far I just settled into a maintance air spray and it seems to work well enough.

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.

Has become difficult to raise & lower blade


I have a similar saw and love it. I saturated the gear with silicon spray and worked it a bit. This seened to do the trick.
