Hello !!!
Some news....
I screw my conga mold

it was perfect, I tried to make a shell but the wax don't do the job and the gel coat glue to the mold....
I don't really understand, it's the firt time..... maybe It was too cold when I done this...
I have to restore it.
Other things, I will use new materials for my drums, I will use linen fiber substitute to fiberglass, I think it will be good for the sound !!!
And I will try super high tech tissu : carbon and kevlar Nice look black and yellow and just super super super super strong !
Some photos of my poor mold and new materials.
Congalou.
