hey everyone,

this question is mainly aimed at Jim and G about these low profile S2 shells that was made, ive just purchased a Heat Gun from ebay to use to melt the coke shells ( plastic ) over the wooden molds is that the best way of doing it ?

or did you use a different method ?

Me and some mates used a vacuum machine at school making wings and shells, great fun but we never got them quite right :thumbsup: never thought of using coke bottles and a heat gun, maube something to try in the future for my own wings.

That would be a great substitute for heat shrink. And it will save me having to go out and buy some. I have loads of coke bottle at home.:lol:

Research is definitely needed into whether or not jack daniels in the coke affects the quality of moulding at all, will drink JD and coke for the good cause of testing, send PM's. :thumbsup:

ive thought about making a mould for a shell of my own design, not sure what the best material would be to make one out of though i've considered wood so far as i have access to a vacform and the polycarbonate or lexan

layers of balserwood ? youd need to use glue and heat and glue dont mix.

one block of wood is fine. :eh?:

i read tht review of the pirahana p2 didn't he use coke bottles there was a link on the boards to a guide on how to do wings it was a german site but in english i think if not the pictures gave me the idea.i tested it out with an old coke bottle and mums hairdryer worked shrank alright i haven't got round to making a mould i will though cos i like the look of the arishi shells but non fit my b4 so that maybe and option also i'm working on extending an rc18 wheelbase so would need a body for that longer chassis

mdf is good for a vacform mold i think

Yeah MDF is great for moulds on a vacumme former. The school I go to uses it for all of their moulds. I have even made a mould for a wing. It turned out very good but the only downside was the plastic sheets my school has to use . I think it is polythene or something like that. All i know is that it is very brittle. I will get a pic up sortly of my mould.:)

nice i wish my product design teacher would let me do stuff like that instead im left doing cswk(even when i go after school) we have the laser cutter prodesktop(3 d design)and vacum former i reckon i could make a car if i had the time.ah welll spose towards the end of the year.i reckon the mdf will work well as its not so porous like wood itself.

The best wood for a mould comes from a type of banana tree called Jelutong http://en.wikipedia.org/wiki/Jelutong_%28tree%29. This is pretty easy to work with but has a very dense grain meaning you can get a very good, smooth finish. Can't remember where i got it from but don't remember having a problem getting hold of it.

When i did a shell for a GCSE project 12 years ago I found that the school vacformer wasn't really up to the task. It was fine with very thin plastic sheet but as soon as I used lexan thick enough to be used for a shell it struggled.
I ended up making the mould and then sending it off to Racecraft for them to mould using the same lexan they used for their shells: -
