Hello all,
 I wrote late last year and asked if assistance could be give to make a mould for a F3 defuser. race car. and that a couple of attempts  had been made with a sad ending, and too the rubbish heap they went.

I have made a mould off the old defuser using glass etc.  and I thought I would use this as a mould for the defuser however, my troubles began when I used foam and carbon fiber to form the underneath ribs and when it was pulled down with the vacumm bagging process the ribs become out of shape under pressure.

I am no expert  with this process and I would appreciate assistance?.
Do you have to have  a split mould top and bottom to form the mould.

I would appreciate your comments, I will take a photo tomorrow and post it until then
Thanks
Sam

I bought some 3m DP490 of ebay for 12.99 a tube which is pretty cheap, we use it in motorsport a lot to bond everything together, if you havent any Hysol 9394 to hand.
Another suitable alternative which robf1 told me about is wurth replast, about 16quid a shot on ebay, you will need to buy the correct mixing gun and nozzles for them though.

But as above if you think you will need to replace them, some nice flush fit fasteners and rivnuts will do the job nicely. 
A combination of carbon and glass works well, if you cant afford the kevlar, Davro Im hoping to make a diffuser in the long line of parts for the caterham, will be nice to see how you get on!

I was going to get one of these, to modify for my own purposes but he doesnt make them at the moment http://www.aerodynamix.co.uk/rear-diffuser-wide-body.html
