I'm getting ready start designing my cafe tail. I'm planning on using a smaill piece of 1/2 inch oak plywood(hard cabinet grade) and then hand shaping a tail out of foam and hand laying fiberglass over that. I will us a layer of plastic or wax paper to keep the resin from melting the foam. I plan on housing the battey inside so it has to be holllow. I will remove the foam and secure the tail to the base plate and then put a final coat of glass and resin. so the seat will be solid fiberglass with an oak core... I just didn't know if anyone else tride this or has an easier way.. this seems pretty simple to me? any input would be great. I tend to over complicate things, but I just thought fiberglass alone would crack under my fat butt!!!!
