Topic tags/keywords: question

I got my new saw delivered on 1/7/12. Right away I noticed I had 4 right legs instead of 2 left and 2 right. Grizzly is sending out the lefts I need and will be here on 1/14. In the meantime I thought I’d prepare some of the other simple things like removing the rust preservative and check alignment.

The saw is .12 off. I have tried to align and have not been succesful at all. I can force the trunnion over, but it takes two hands which leaves me none left to retighten any bolts. Table mounted trunnion with 3 bolts on each end. I have tried loosening 5 and used the 6 as a pivot. I have all 6 loose and the trunnion isn’t moving easily. I can’t get a clamp in position enough to good any good

Any suggestions would be appreciated

Are you trying to move it by hand? Use a rubber mallet or a board with a hammer. Keep the bolts somewhat tight while moving the trunnions.

I have seen it stated several times here on LJ’s that the G0661 has a similar trunnion design as the 21833 and R4512. If this is the case, you might try loosening the 90 and 45 degree stops, which on the 21833 at least will allow for a lot more movement of the trunnion assembly.

+1 on a rubber mallet. A couple firm whacks, then recheck. Adjust your force as needed.

What you’re going through is one of the reasons I despise table mounted trunnion saws.
They need to become extinct.

Good luck with it. You should be able to get er dialed in. Use the ole “persuader” to adjust.

At 90 degrees and full height I got the alignment perfect. I know how to achieve this now. Next issue is 45 degrees at full height. The back of the blade drops .009. So this means I have to drop the front end by placing a shim or really thin washer between the underside of the table and the trunnion. I found a link that explains how to do this. According to the link, in my situation I would need to drop the front end by .025.
The math is .009×1.41 (1.41 is one over the sin of 45 degrees) x 2 = 0.02538
Does anybody know this a correct way to fix my problem.

Any opinions is appreciated

check out the write up in this ridgid forum thread:

https://www.ridgidforum.com/forum/t25836/

it addresses alignment @ 45*. although its for the 4511, which had cabinet mounted trunions, the calculation of the need for shims, the size of the shim(s) and their placement (which corner) still apply to table mounted trunions. the shims would just go between the underside of the table and the trunion as you indicated above.

Thanks toolie...Great info and applicable to my situation. Took some calipers to the hardware store. Sifted through washers til I found some close to the right thickness. Bought a couple extra. Attached them all to a board with double sided tape. Held the board washer side down onto a belt sander til they got to about the thickness I needed. End result is I got the tilt-axis within a couple thousandths

Nice work.

I know this is an old thread, but I too was having alignment issues with my G0661. So I thought maybe I would write about my experience in the hopes that it might help someone else. Of the six bolts that hold the trunnions onto the the table top, five of them have a 13mm head and one has a 14mm head. Upon inspection, I could see that the 14mm bolt ( center bolt in the back ) was meant to be a pivot bolt since it had a collar. Being unable to move the front trunnion assembly as it was, I decided to move the pivot bolt to the front center position and see if I could move the back trunnion assembly. It worked. I was able to move the back trunnion easily and get the saw blade aligned with the miter slot. I still need to check the 45 degree measurement to see if I need to add some shims, but I am thrilled that I finally made some progress. It was an easy fix, but it took me a while to think of it.
