Looks to me like your material isn't flat, as seen in the second picture. Also if that's a 12" saw there will more than likely be some blade wobble. Is your fence square to the table?

New blade didn't help.

I've cut many different pieces and sections of material and it's not getting any better. With the DeWalt, that last inch or so on the 45* miter, the blade cuts down to the left for some reason. I forget what it does on a 45* miter the other direction.

I see several potential issues.....

It looks like your stock is not sitting square on the table....what are you using on the end to support the stock? I have an adjustable roller that I use if I'm not using my fixed table. If your stock rocks either up or down, your going to have a bad cut.

Second....I personally wouldn't cut it vertical like that. I prefer to tilt the head 45 deg and lay the stock flat.

Good eye/info. That was just a mock-up for a picture. The stock is sitting flat on the table. This cheap flimsy stand though, I need to adjust the height as I get closer or further to account for the weight flexing the arms. Further out, it sags more. Closer in, I need to lower it so it doesn't sag so much. All that to say it's properly supported during the cut, I have to check each time since the old stand moves.

This DeWALT stand is much much better, much sturdier.

You can see the cut it makes with this DeWALT with a 45* bevel cut...not pretty at all. It's curved. From what I can see and watch, most people cut it straight down against the fence to do a 45* miter? Survey Says?

So is it making a bad cut laying flat on table or standing on edge?

Both.

Standing on edge, bevel @ 0*, miter @ 0*, it makes a perfect cut.


Standing on edge, bevel @ 0*, miter @ 45*, it makes this cut. It cuts down straight-straight-straight, then the last 1-1.5 inches, it hooks left.




Laying flat, bevel @ 45* (head flopped left), miter @ 0*, it makes this cut. You can see it's taking more out of the middle than the outside edges.

The bottom picture shows the trim is cupped, lay a straight edge across the face and see if it is flat or not.

OK I will do that. I noticed the rear profile of the new molding I bought is different than the old. You can sort of see the old profile in that bevel cut. The middle is recessed.

This is the new back. Just a different company/mill? Better design?
