Mini hydro motor mount

[BIGDG357]

I am starting to build a 15" mini hydro from Head Of The River (Ebay).I have everything for it The only thing i am stuck on is the motor mount. I cant seem to find one the only thing i can think of is to find a small sheet of fiberglass or carbon fiber and cut one out but a drop in would be nice though.Does anyone know where i can find one or what material to build it from. Oh and its a 28mm ammo motor.Thanks.

Sheet alumimum is easy to make motor mounts from
