Topic tags/keywords: ridgid r4512 newbie table saw alignment

Hello folks, my first post here. I have been stalking a bunch of forums for a few weeks now, and have been wanting to get into woodworking for over a month or so now. Well, with tax season here, I decided to make the plunge and buy the Ridgid R4512. I know about the raising and lowering alignment issues, however there are fixes available for that. My problem is, as a new woodworker, I have absolutely ZERO experience with aligning blades at all. When I follow the manual to align the blade, even after trying for hours, I get no progress in aligning my blade. I do not have highly precise tools to test the alignment, so I am using the combination square in miter slot technique. The front of the blade has solid contact with the square, while the rear has an obvious 1/32” – 1/16” gap. So my question is, what tips can anyone provide with aligning a table saw blade such as the R4512? I searched online for hours, and cannot seem to find anything that helps. Any tips would be greatly appreciated.

So you are loosening the trunion bolts and moving the assembly to align the blade with the miter slot. What I did just a few weeks ago to realign mine after a bone head move was to get it close and then keep the bolts snug but not tight and then tap either the front or back whichever needed to move. Tap with a hammer and then check. Repeat if necessary and tighten down when it’s good. No fancy measuring devices here either.

a. make sure your miter gauge is snug in the miter slot but moves with no side to side slop
b. get a $10 dial gauge from harbor freight
c. get the owners manual for your saw
d. follow the instructions in the OM.

that’s what i did with both my 10” contractor saws. they are either .000” or .001” relative to the miter slot:

So, from the sounds of it, I have done all I can with what I have. The most effective method seems to get the Pals kit and a Dial indicator. The problem with the Pals kit and the R4512 is that I will need to grind the rear trunniun down, which I do not have the tools for. I suppose I could pick up a couple metal files and the dial gauge from harbor freight, and file down the rear trunnion while I wait for the Pals set to come in.

Are there any other recommendations or is that my last option?

That is really good news.
The fact that “there are fixes available for that”.
I have one of those piece of crap saws and have been looking for that FIX for about 6 to 7 years now.
Strange that I have never found it.

The only “fixes” I’ve heard of so far, didn’t pan out to actually fix the issue. Please share what you’ve learned about a fix for the R4512….it should also apply to the 21833 and G0715P.

Most people seemed to have fixed the issue by replacing the rear trunnion with the on labeled with a “II”, and when raising the blade to max height, lowering it slightly to relieve the pressure off the blade, then it seems to go back to perfect alignment. I would love to see if mine is like that, except I cannot even get it aligned. I am going to get a dial gauge and some more clamps. I looked it up and some people seem to get it aligned by loosening all 4 bolts and clamping them together, then I will make the adjustments. I will update to see if that helped at all. If it does not, I will buy a Saw Pals and see if I can align with that.

I also noticed that they recommend buying the 5/16” saw pals as it is longer, and drilling out the hole larger to fit the R4512, of course getting a new bolt while you’re at it.

skip the pals. modifying an alignment tool because it doesn’t fit your saw sounds like a less than optimal approach.

It would not be a big deal honestly. If getting the saw pals and adjusting the gets it in alignment, then this is a solid saw for under 500 after the pals. (10% military discount at HD got me a solid deal.) If I am getting bad alignment based off of saw blade height, I dont see much of it. The OM and other users reccommend backing off the height of the balde at a certain point, which seems to work fine for me. I got a dial gauge from HF and with a makeshift alignment test, I believe I got it .006 – .002 in alignment. Hard to tell as my only way to measure is fairly wobbly, but that is acceptable for me. I just need to replace the blade, it has a .007 wobble to it.

(All measurements are in inches)
