Yeah, I'm pretty sure the boards are flat.

Saw cuts inaccurate angles


so there is no gap if you put a straight edge across the width of the board?

The problem isn't that it's a Black & Decker. The problem is that it's a Fire Storm that cost all of $99. Even a B&D would have been a step up I think. LOL

nope, no gap. I've tried it on several boards and even some MDF trim. They all cut the same way.

have you ever cut a board with your saw tilted like that before?

Yes, I've cut a few boards with the saw at that angle before. And I almost always have the same problem, but I really don't want to make any more cuts until I can get it right.

Well.....that would explain a lot of things around here.

Saw cuts inaccurate angles


and the answer is...! ok, ok...
looking at the piece on the table, you start out ok, but drag the blade down into the piece, thereby creating that weird cut.
it'll take a few tries, but tip your head as you cut and let the saw do all the work. be sure it's completely revved up before starting the cut. try it, i'll bet you get a perfect cut. if all your measurements are correct, then it's not the saw.... it's your toolnewbieitis acting up again is all...

Saw cuts inaccurate angles


If the saw is consistent you can, in principle, adjust out the errors and offsets.

Your angle measuring devices should have 5x or 10x better accuracy than what you're checking.

The geometry we all can help you with, and using plywood will give you dimensional stability. You just need straightedges, a ruler and a calculator.

Probably the best you can do with ordinary effort is 1/16" in 6", about 0.6 degree.

A saw blade is supposed to lie in a plane, but a dull blade will deflect with pressure so the blade surface becomes curved. I've seen this with bowsaws cutting trees.
Try cutting very slowly.

Be careful; hand surgeons in the DC area charged one to four kilobucks per hour, in 1994 prices, and for this kind of money your hand works afterwards, sort of.

Hmm....okay, I'll pay attention to how I'm pushing the handle down.

Thanks
