idiots guide to fiberglassing please
Im going to be widening my scuttle soon and would like an idiots guide on how to do it.
It needs to be widened about 200mm so the plan is to make a mould over the current scuttle, then cut he scuttle, fit the mould over the now seperated
scuttle at the desired width and clamp etc, the lay up the inside, then remove the mould, then fill and finish.
So im after an idiots guide of exactly ow to do it, what to use and everything so i get it right. Including what resins and waxes etc to use.
Sorry for being a pain, just want to get it right first time.
thanks
Mikkel

A better plan would be to cut and widen the scuttle , fill it smooth , then take a mold off that and make a new scuttle .
Any joins will show in time 
Its cuz I is blond , innit

There's loads of stuff on you tube, some of it quite good, you may need to put 'mold' in the search box because most of it is
American, and they can't spell mould.
(and 'fiberglass' will probably get more results than fibreglass  )

If you cut a straight line it will show, if you cut wide zig zags you greatly lengthen the bonded join so its stronger and no-longer have a single
failure point. It also lets you blend in.
I screwed my cut nose cone to some wood to hold it solidly, laid duck tape over the gel side and just layered fibreglass up on the inside edge.
Once cured removed duck tape, filled and sanded the top.
Cut like this VVVVVVV

i see what you mean mark, wouldnt it be better to have rounded edges on the cuts so theres no concentrated stress points?
But will defietly do this to make it stronger and look better

Rounded edges are good indeed, just lazy drawing, I used a jigsaw and wiggled my way along turning as tightly as possible.
If adding 2" make the spikes 2.5" long then you can cleanly bridge the gap, it helps maintain the smooth curve as well.
It's how the good hot rodders lower the rear roof, the lazy ones just cut straight and fill... It also means you will not see a straight crack
appearing as the scuttle flexes over time.

How wide is your car?
For an easy way, that I have done successfully myself, if I may add, go to Kinetic Vehicles (Jack McCormack) and see how he does it. The key is to
hold the two sides in the exact position you are going to want, with the bits of wood. Then you fill it in and if you do a good job, won't have
to do a lot of bodywork.
Also search Mr. Whippy - widening cycle wings - thread on here.

its not so much that the car is very wide, its more the shape i have made the chassis, normal bodywork wont fit properly, so the scuttle needs to be a
fair bit wider than normal
