just about ready to start making a scuttle/dash on +4
any hint or tips

A couple of alternatives to plug-and-mold fabrication are (1) making a flat, thin, flexible sheet of GRP, bending to shape, and building up from there, or (2) building a negative mold.

Interesting (to me, anyway ) discussion starting here:

FWIW,

Within the last week someone posted some info on how they're 'stretched' their scuttle for +4". They'd used some sliders glued to each half to keep eveything in line but still allow him to move it apart.

However you decide to do- keep me informed please! I'm dreading having to do this bit of the car. So much so, in fact, that I wish I hadn't widened the car!

Good Luck,
James

I made mine to suit plus 4".Made the "plug" out of wood and plastic,filler etc.Spoke to GLASPLIES(adds in the kitcar press.They will send you a info pack on how to do it.I brought all my bits from them as well.A bloodly good service from them.(I got the cheapest stuff avalible,Reblended resin etc)Made the mould,A two piece job and had quite good results(see photo achrive).I,ll be doing it again for the next one.give it a go

Ref. the thread referenced by James... Isn't that how to narrow a scuttle, not widen it?

My chassis is also +4" and I'm thinking of either widening a fibreglass item or making a s/s one. Given the need to radius edges etc, the s/s option looks too difficult, so I'm back to how to stretch a standard item.

Now then - if the guy was shrinking a Tiger item? how wide was it in the first place? It wouldn't be +4" would it?

It was me, I needed to reduce the scuttle because it over-hung the chassis rails on my tiger cat chassis. However by jigging the scuttle with the plates I describe you could also cut then stretch the scuttle to the desired width then lay up material in the gap. The plates just keep everything aligned while you are doing it. Also note that fibre glass continues to cure for several months after it has appeared to have set solid. Make sure the modified scuttle is supported during this time or you may end up with it out of shape !!!

I was going to say have a look in my photo archive - but there is only an unused plug in there!

I made a female plug (if you wanna call it that.

Two sheets of 5mm MDF - with the shapes cut (as slots not cut outs). Ally sheet fitted into slots.

Greased, then gelcoat and lay up!
