HT Autos 'PROJECT' Version 8 Spoiler Mould!!!!
This type of mould has been 6 months in planning here at HT Autos and so far hes taken us a month to 'nearly' complete top half of spoiler.
Benifits of this system, is that we will be able to produce a spoiler far more superior to any GRP/FRP (fibreglass) replica's out there.
This system is the same that PRODRIVE used to manufacture all the production P1 spoilers and this project is being supervised by BRIAN GRAHAM ( the man who made the mould and all the original P1 spoilers).
It works using Polyurethane foam, which in a reacted state will expand about 30 times in volume, but with the help of 10 ton of pressure ,we will only let it expand less than twice, which will form about 2mm of rock hard plastic skin and a very dense urethane core, which is lightweight and extremely tough.
Pics so far ,below.......
Tooling on stand at angle of 15 degrees..
2.5 Ton toggle clamps...
Specially made adjustable hinges...
2500 newton rams...
There is more urethane in model than foam block....
This pic shows strength on 1mm section...
Hope this is of some interest to some of you?
Cheers for looking!

Pipework is buried in another layer of Paste Laminate.......
Next, hardware is put into place, which will support hinges, clamps ETC.
Then a mixture of Epoxy Resin, Binders, Chopped Fibres and sand is used to top up!.........
