So if you determine the radius of your circle, you can then double it then multiply by 3.14 to get the total circumference. Divide that by 4 (for ease of calculation) to determine the length of 90 degrees of the whole. Once you have the length measurement calculated, you should be able to divide that by your desired stave width to get the total number of staves in 90 degrees. Divide 90 degrees by the number of staves to get the angle between each piece. I think that would then be cut half on both sides of the staves to get the proper arc. Let me know if that isn’t correct. I was pretty good with geometry, but I have never actually built any of these curved pieces
Hi Wayne, these directions are great. Question- when I made my top arch 6" the circle trace went off my sides leaving a 3 1/4" straight edge each side. Is this going to be an issue? My treasure chest lid needs to be 16 3/8" wide. center of that is 8 3/16". The intersect was 14" I used to trace the half circle. Wish I could attach photo of template to help explain. Should I make the arch smaller to meet the 16 3/8" width?
Thank you so much. Finally someone who explains it in simple terms and not on an advanced level. Not everyone is a mathematician. Thank you again.
Thanks for your time and patience. Have a blessed day. Happy Father’s Day.
Thanks for sharing. I learned a lot and will make a treasure chest for my grand son.
Thanks for sharing this -- I used your method and it works very well. Now I am going over it again to make a pirate chest for my youngest grandson.
Thank you saved me so much time.
You are welcome. A Pirate box sounds like a fun project.

This was painful to watch.
