I’m having a problem with the corners of lamp’s shade that is in the attached image. At first I made eight boards and cut the edges at 45 degrees, then glued them together to make the four 90 degree corner. Then mortised them to match the tennon work on the rails. When I went to assemble everything I found out that the miters where to acute and I could not put the last “panel” in place. I triple checked the corners and sure enough they are all at 90 degrees.
My question is, does anyone know how to figure out the angle I should cut the corners in order to get the lamp shade to come together square? The lamp comes in at 66 degrees from horizontal on all four sides.
Thanks in advance for the help, John

That's an online calculator for compound miter angles. Good luck, and post a pic when you're done.
Is that your SketchUp drawing? If so, why don't you just measure it off the drawing? Or send it to me and I'll measure it for you.

I'm still new at Sketchup so maybe I'm measuring my angle wrong. I tried with the protractor tool, but it gave me 90 degrees for the angle and I know that is not true.
Dave, if I could get your email adress I'll send you the file. I would appreciate your help.
I have also tried the online calculators, but am confused as to what information goes where.
Thanks for all the help, John.
I sent you an e-mail.
Adrean22,
Would you mind sending me / posting the magic
formula when you get it? I just built a floor lamp
in a similar style and am wrestling with the
same issue!!
Thanks!
Bill-
