WELDFAN

Maybe mikes still sells the one that is plain without the Yam name. You can use it as a form to mold the lexan to it, get the curved bulge. i guess you can fill weld the yam name too on a stock unit then grind it smooth to make your own die and save a few $.
im actually using the original cover to form some right now...which happens to make the yamaha come through. i found an optimal bake temp, time and cooling procedure. so im forming up four of them to start dabling with the aluminum overlay and bonding techniques. by the end of the week i will have some pics of final pieces
