Topic tags/keywords: tablesaw question

Heya jocks. I need some help. I am trying to adjust my Delta 36-979 contractor table saw, and I am having a difficult time getting the blade angle at 90 degrees from the table top. Fully rotating the bevel handle gets me half a degree short (and that is with the 90 degree stop setscrew totally unscrewed). Is there another adjustment that will allow me to adjust the trunnion so that I can get square up the blade?

Thanks in advance for your help!

I just had a similar problem…..not familiar with this table saw, but when you are trying to get to that exact 90 pay attention to the side of the table saw….if the metal is too thin, it can suck it in, or bow it out, while turning the handle….that might be the problem…

Not familiar with this saw, but has it ever been at 90? If not, may need to reposition/shim the motor mounts. Sorry, not much help here… this is a fairly “saw specific” adjustment.

On my hybrid, there is another lock in the middle of the wheel itself—take that loose and it should allow you to turn the wheel more and get to 90. Then set your stop screw and retighten the knob in the middle of the wheel. Of course, mine is the Steel City/Craftsman/Ridgid granite top hybrid, so this may not apply, but I was living in your world of frustration until I found the manual and made this adjsutment.

Don’t have a Delta saw but had a similar problem on my inexpensive Craftsman saw. The trunnion and threaded rods were coated in sawdust and lubricant, cleaned that up and could get a true 90 degrees, your mileage may vary :-)

The issue came up after a cleaning (it would hit 90 prior to the cleaning), so perhaps I blew some sawdust somewhere it shouldn’t go. I had had some difficulty turning the bevel crank (but some lube cured that), but perhaps created a new issue.

Thanks for your help, I’ll keep you updated.

Maybe the stop was set incorrectly. I dont have a delta but my Craftsman has a collar with a set screw that limits movement ie the 90 degree stop.

Let me know if you think this is a good way to proceed. My blade is ~1 degree tilted to the right when fully displaced. If I shim underneath the trunnion on the left side (by about ~.020”), that should tilt the blade to the left the required amount.

Any ideas why this wouldn’t work?

Seems to me that you wouldn’t want to try and nail 90 deg. with the shim itself. I would think you would want to use the shim to get you to a position that would allow you to use the 90 deg. stop set screw for your final adjustment. I would put the set screw stop in it’s “middle” adjustment position, shim the motor/trunnion so the blade is as close to 90 as you can reasonably get it, then once it’s all locked down, use the set screw stop to make the final adjustment. Once the blade is at 90, recalibrate your degree gauge.

Agreed, Clay. I would want to hit 1 degree past 90 and then re-set my hard stops.

Have your say...
