Topic tags/keywords: question compound miters

Fellow LJ ‘ers, I have a small problem for a small project. I have taken on a request from a friend to build a four legged tower to support a 1 1/2” glass globe. The tower will only stand ~3” tall with a 2” square platform on the top. The legs will splay outward from the platform 10 deg. in both directions. I’m trying to calculate the compound angle of intersection of the legs to the platform and the angle at the top and bottom of the legs for a level surface/footing. I will be using a radial arm saw and/or coping saw. Any advice or direction you could send me would be greatly appreciated.
P.S. By the use of “Fellow” in the salutation, I do not wish to offend or dismiss any of our female contributors, I merely did not know of a non-gender specific friendly opening to use.

A compound miter saw would be the best option if available.Set both angles at 10 degrees,cut some scrap,and check your fit.

If you google “compound miter calcualtor” you will find a few web pages that can do the job.

I have used to calculate the angles for a compound box joint project. He has both miter and butt joint calculations on that page. It sounds like your project needs butt joint figures.
