Ahh, I see. I'll have to shim down my jig a tad thanks

When I did the arrays for my DR250s, I glued each side up, then cut the 45s as full units.

I found the angle would match up better if I did it that way.

Actually, that's her hand next to the can of paint. I tried to include her on some aspects of the build. Painting, however, did not seem to be one of her favorite things. Learn somethin' every day
