I had previously coated the Balsa plug with some varathane, and sanded it smooth. To extend it and make it a little larger I also added 1/8 inch ply, forward aft and the underside
Some ultracote was added to give it as smooth a surface as possible
Blocks of wood and a stick make it easier to handle while I do the glassing. Prior to adding the 1st layer of cloth I gave the plug a few coats of clear carnauba wax
After the 1st layer was set I went around the edges with some heavier cloth strips and added a couple cradle supports
Next up heavier cloth all over, actually a couple layers
Out, released very easily, and then of to clean and trimming the edges
Hope it works, will check the surface for marks etc, and clean up nicely.

I added a couple layers of cloth, and a strip at each end
Then a piece of wax paper and pushed the air bubbles out
Some 12 hours later
A piece of balsa at the forward end
