Thread: square cuts with the blade at 90, out of square at 45???

Did you notice if the deflection was off by about the same every time you tilted between 90 & 45deg?

I wouldn't expect blade deflection unless you're using a low-end blade. I don't know if that particular saw uses trunnions or something else, but there must be a front/back pair of pivots that the saw angles on. If the axis between those two pivots isn't perfectly parallel to the table surface AND ALSO perpendicular to the motors axis of rotation, then it's an error "built in" to the saw.

You seem to understand making jigs... perhaps you'd have better luck if you ignore the saws tilting function altogether and leave it set at where you know it cuts 90deg fine.

Then make two cross-cut sleds. One purely for cutting at 90deg and the other with an adjustable table that you can angle up. Then you can cut the mitre angle on the end of the plank you just cut to length with the first jig.

A bit of faffing around, but it'd possibly improve the accuracy of cuts possible on it.

Perhaps have a squiz at this thread: Aligning cabinet saw to 45°

Thanks for the advice, guys...One thing I noticed today after taking another stab is that my idea of square was thrown off by the fact that when I tilt the blade, for whatever reason, the blade doesn't cut a clean line...by that I mean sometimes the cut will have a slight arc, or a slight concave curve to it..not sure if the arbor is a bit worn out (I've thrashed this saw for 3 years straight) or out of whack and when you tilt the blade it somehow cuts wonky? But compensating for that, I think I've managed to get it pretty square after another session today.
