With all the stuff cut up it was time to make the arch. It is about time!
Since the arch will be about 40" wide a form is needed to create that bend and in this case, forming up outside the arch seemed reasonable.
Thus I started with 2 pieces of flat 3/4" plywood 4' wide and crosscut to 28''.
The center of the plywood was marked on each piece,
then that mark was continued all the way up with the framing square.
I made the compass by counter sinking the counter sink bit ( until a pencil point of lead would poke through) at the end I wanted to use the pencil at. Went too deep with my drilling but not so deep that I could not control the accuracy. Then measuring from that point I made several different holes to be used as the compass points.
First a drill bit and the nail to be usde for the compass point.
With the drill bit made, we can drill a hole that the nail will fit!
This is a photo of the compass and it's job. Visible are the numerous holes set 3/8" apart ( for marking the bent plywood layers).
