A pictorial Saga of my Elliptical prosecenium build
The total width of the casing is 16' and the ellipse is 12'
Split 2- 4x8 sheets oak ply in half
set 2 halves end to end and traced an ellipse using the "String and 2 Nails" Method.
Then i staked the 1/2's and Cut it out with Jig Saw
Transferred the pattern to the other 2 halves and repeated
Stacked the 4 sides together and sanded the elllipse to smooth out the jig saw cut.
Routered a 1/4 x 1/4 groove in each arch.
Assemble 1/2 the arch.
Each 1/2 of the casing is 8' wide
Broke the first 1/4" oak ply I tried to bend around end radii.
So I steamed the next one.
Check out the Getto Steamer...
After it was soft , I just pressed it down in the routered groove and clamped it in place to cool.
After it was glued i test fit the 1st half.
I built the arches 5 9/16" inside the casing so I could use a 2x6 to slide over and mount.
Assembled the 2nd 1/2 of the casing then cut a keystone from a left over oak stair tread.
Routered the edges and attached this oak lion head I picked up off of ebay.
Shot of the test fit for the full arch and keystone.
I angled to keystone os its looking right at the seats.
I still need to finish the keystone with sides and a full bottom so its looks like it is the depth of the casing.
I'll take everything down now to add the lights in the casing, stain, and finish trimming it all out, and build the screen wall before putting the arch back up.
I'm not sure I like the keystone's size/scale. I might want to cut a little off of the width so it doesnt look so much like home plate. I'm thinking about cutting the sides in closer to the lion's mane, but i cant decide, I'll look at it for a day to see how it feels. any recomendations.. cut it narrower..? leave it like it is...? use it for kindling....?
