Topic tags/keywords: ryobi rts21g trunnion tablesaw alignment

I am new to woodworking in general as well as being brand new to I’ve been wanting to get into woodworking and decided to pick myself up a Ryobi RTS21G table saw. It’s an alright table saw, but I’m wishing I spent a bit more and got a DeWalt or Bosch.

First thing that irked me were the non-standard mitre slots. I bought some cutting blades for a cheap Dremel I had and took them off. They aren’t amazingly straight, but I can at least drop in mitre bars properly now. This pain alone makes me wish I bought a table saw with standard mitre slots. But whatever… I’m passed that now.

The issue I have now is that the saw blade isn’t perfectly parallel to the mitre slots. It’s off by about 2mm which is causing my cuts to be off, especially thinner cuts (my mitre bars for example). I’ve been reading about adjusting the trunnions in order to align the blade, however I’ve had no luck.

On this specific saw, there seems to be 3 brackets holding the trunnion in place. I’ve loosened the bolts on all 3 brackets, however I just cannot move the blade for the life of me. It seems that the pre-built holes where the bar is placed has almost no give to it. Therefore I can’t align the saw blade.

If anyone has this model of table saw and was successful aligning the blade, any help you can provide me with is greatly appreciated. I want to build a cross-cut sled and get started on some projects, but this alignment thing is a real pain in the rear.

If I’m not mistaken the table for that saw sits on a set of rails that sit on top of the box. Try shimmying those around, or the table itself. I think you’ll have better luck.
