i know this is a old common question but advise please. i have a riigid 3650 table saw i have had for years i bought new. it has always been a good saw but lately i cant get it to cut square. i have put the dial indicator on it from the miter slot to the saw blade and its very true within maybe a thousandth from front of blade i marked with sharpie and rotated to back of the blade. even a brand new blade. i also ran the dial indicator from miter slot to fence in many positions and it is very close. after many cuts on 24×24 panels they are always out of square. 1/8 inch diagonally . the fence has that “factory slop” but it locks down tight. is this common with the factory fences? will a new better fence cure me? any suggestions for a new fence, as i have been out of work for a while and money is a issue. delta t2 maybe or others. thanks for you input good sirs

check for adjustments on the fence. i know on some fences there are set screws that will allow you to adjust the angle to match the blade.

I have to agree. The fence seems like the culprit here.
Try cutting a piece while the fence is held firmly in-place with a C-clamp (or similar). See if that helps. If so, then you’ll KNOW its the fence.

Check and see if you saw is making parallel cuts. Rip a piece of plywood a foot wide and accurately bothe ends and see if they read exactly the same on each end. If not then the fence, blade or both need attention.

Unless you’re use a miter gage, sled or a sliding table, a table saw doesn’t’ make square cut it just makes parallel cuts. If you start with 2×4 panel that’s not square to start with it’s not going to get square by cutting using the fence alone.

Are you use a good sharp blade?

I once resolved the issue with a new, high quality blade. I couldn’t figure out how the saw could be cutting out of square when everything was adjusted perfectly accurate, then somebody suggested the blade might be dull and causing it to veer to one side or the other as I was making the cut. Also, if you’re using a thin-curf blade replace it with a thicker one.

I am with Ted, a dull blade will ruin your whole day. Check the cut and see if it actually cut or torn wood. A couple of dull teeth is all it takes to veer to that side.

Exactly.

Also, after cutting, instead of measuring each end, flip you piece end for end and check the gap you have. If there is no space between wood, fence and blade, your problem lies with the wood supplier selling you shop grade sheet goods and not letting you know that important piece of information. ............

Not sure if this might help but on my Ridgid R4512 I find that I need to push the fence forward to get it square. I can actually see the fence swing over a little bit when I do that. Hope that helps you.

The very first and most significant measurement in any table saw is the blade square with the miter slot. If you can,t make that happen get a new saw.

Yes everyone on here with a R4512 feels your pain!

Cutting a perfectly square panel is NOT as easy as one would think and it seems every little variant is there to be against you..

My ridgid TS will cut straight rips but it seems to not touch snuggly against the rip fence twards the outfeed. Cant seem to figure that one out
