I am tuning up my saw and checked my 90 degree stop (with a digital magnetic angle guage stuck directly to the blade) I found I was a half degree off from 90. As I continued to move my guage I found that I had to actually put some washers between the stop and the trunnion.

See picture below.

Is this normal to have to do? I have an old G1022 TS

Idk why but I think my digital angle guage is off somehow? When I stick it to the blade (magnetic base) it shows it is off from 90. But when I check with my square it shows that it is spot on with no gaps.

Did you flip the gauge around so the same
side is facing up when you measured?

Just occurred to me.

Somebody else posted recently about those
box gauges being off when checking the other
side of a saw blade.

Good suggestion regarding handling the angle cube. Given the sawdust can accumulate on the stop and affect its accuracy, I never use the stops on either of my saws. It’s surprising how little sawdust it takes to affect the angle.

It’s hard to explain, but those angle cubes are only designed to give you the angle of something in relation to whatever surface you zeroed it out on.

Also, make sure you aren’t attaching it to the blade near the teeth.

As Loren mentioned there was a discussion about the inaccuracies of those cubes. I have one and tried the same thing are doing to square up my blade. I would get it square and then the tried the other side of the blade would measure 89.9 degrees. But the accuracy of the gauge is only +/-0.2 degrees so it was within tolerance. The other thread referenced a FWW article (237 I believe) that tested these gauges and found gaps between the blade and a square (drafting square, I believe) when these digital gauges measured 90.

So it appears the digital gauge cubes are not the jog for blade angles.

Hope that helps.

Most saws have 90 and 45 degree stops that are adjustable. They typically involve adjustable stops on the screw mechanism or something similar.

My Wixely digital angle gauge seems to be very accurate. If I zero on the table, move it to the blade adjust it to 90, rezero and move it back to the table, it will read exactly 90 again.

Perhaps I am not interpreting what I see in the picture correctly. I see the washers you stuck in there and I see a bolt with a jam nut on it but it should be sticking out the other side of the stop for setting it to 90. It might be as simple as loosening the nut so you can turn the bolt to the same point as those washers are holding it and then tightening the jam nut to lock it in place. There should be another similar one on the other end to set it to 45.

Note: Even with my 90/45 stops set close to perfect, it is still possible to pass the setting by over tightening so I generally have to stop as soon as there is any resistance. The stops are good enough for government work but if you need precisely 90 or 45, measure.

I am not familiar with that saw, but looking at the pic – isn’t that an adjustment screw with a lock nut directly below where the washer is placed?

My Wixely is also accurate. Zero it on the table then check the blade. Cross cut a board, flip over one half and match the cuts. If there is no gap your good to go. If not you’ll be able to adjust the blade to the right direction.
