Should My Transom Have an Arc

[Kracker Jack]

I used 2 pieces of 3/4 ply. The first piece of 3/4 ply I cut 4 relief cuts in it,I went about a third of the way through just to give enough relief to easily make the contour of the factory arch transom. If you use 3/4 ply the first piece you glue and clamp to outside skin will want to pull to the skin to the ply but with minute relief you will pull the ply to the skin. The second layer of 3/4 ply is cinch you don't have to relief cut this piece because structualy integrity of the transom is already establish with the first piece of ply. Or you could use 3 pieces of 1/2
