Question

I'm building a wishing well, its in a 48 inch diameter circle. The walls are 2 x 4's cut 7 7/8 inches long and they lay on the perimeter of the circle 10 high. The plans call for a 2 x 6 cap at the top of the wall. The cap is angled so that all 19 pieces fit snug together when the cap is done. The 2 x 4 walls are not angled, probably a good idea as would give good drainage when it rains. What angle do I cut the 2 x 6's to make a snug fit on the cap with 19 pieces cut at 7 7/8 inches. P.s. the boards can be longer or shorter to make the snug cap.

Answer 1

9.473

Answer 2

i don't think you will get an accurate angle trying to figure it out. i.e. 4 pcs. require 45, 8 pcs. 22.5, 16 pcs. 11.25, etc. it will probably come out to something like a 10.125 angle. how would you ever be able to set your saw to that, unless you had a micrometer?

it would be easier to take 19pcs cut about 10" long, lay them out overlapped into your final arrangement and mark them.

cut them all except the last one, and then adjust the last one as needed.

Hope that helps.

Answer 3

In order to get the angel of the 2by6's dry fit each one where it belongs scribe it with your pencil then cut them

The boards can be longer

Answer 4

Since the well is a circle, divide 360 degrees by the number of segments, 19.  The answer is 18.947 degrees. The angle is correct but I cannot tell you exactly what length to cut the pieces.  I would cut all of  them long and then start trimming off  at the same angle to make them fit.
