Yeah I'm going to set up a test piece with different pass depth settings. I was reading more about clearance pass depth (apparently the depth used for when a v-bit has to make multiple cuts down to flatdepth) but it puzzles me that this could be the issue, since I see problems even at very shallow depths (like with a .05" flat depth!).scottp55 wrote:Try some more conservative pass depth tests maybe?
Bit angle test looks like angle is correct.....kinda thinking machine flex from pass depth?

I was satisfied with the test I did and I'm still skeptical that my bit angle is at fault.. but who knows. If other tests don't pan out, I may re-run an angle test at the single degree interval just to be sure.TReischl wrote:Well, it looked to me like there was a slight curve in those sides, but that could be an optical illusion caused by the overcuts in the corners.
Running tests at 55, 60 and 65 is WAY too big of a difference. That should be more like 55-65 in one degree increments and then look at them with a magnifier and a straight edge. I would also NOT cut them in particle board for testing. MDF would show things a lot better. Well, maybe that is MDF, but it is a lot lighter colored than the stuff I get. It looks a lot grainier to me too. But hey, pics can be deceiving.
It is MDF from the local big box store, the photo is a little zoomed so I think it looks grainier than normal.
And thanks for the feedback everyone! Slowly chipping away at this problem, hopefully can solve my mystery soon. I've stared at my test cut pieces for a long time trying to work this out, lol!
