New Edge Hood Scoop Feeler thread

[g36 monkey]

I aim to cast a mold of the stock hood scoop on the new edge cars to make a few for some friends of mine.


Would anyone be interested in one (once I get them finalized with nice quality) for $100 or so?

I know you do glasswork for a living but have you done much in the way of molds? Curious as I still want to do the drivers side window louver and use it as a plug, after a long list of other projects unfortunatly.....

I've been talking with mold engineers at work to make sure I don't have any issues with this. Because of the shape, the scoop should be really easy. Waxing it like crazy, putting it on a piece of plywood, then laying out some material on it to make a basic mold. Make it good and thick. After I pop it off the scoop, then I glass some wood to it to make a box for added strength. Fill any voids and gelcoat it, then finish it.

Then I could start casting parts out of it.

Your louvers would be more difficult because they have the cuts in them, I could talk to the guys at work, I'm sure someone would have an idea.

I thought you were supposed to gel-coat the plug even before applying the glass, and what was the crap called pva or something like that before the gel? I understand the challenge with teh louvers and figured like other fiberglass louvered things(hoods for example) that they would need to be trimmed out later if someone wanted them open.

PVA is a parting film, it's just to add some lucidity, making the part pop easier. Exactly the same thing as wax. You can use Pam on molds instead of PVA, I'll just stick to wax though haha!

But no, you don't need to gelcoat the plug, you just wax it like crazy, put wood underneath it so you can make a flange. You actually don't even need gelcoat at all, I could pop parts off of that mold after I strengthened it up with some wood, as long as I wax it well enough. Then pop the part, prep it and paint it.

Someone gave me an idea to make them about a 1/2" taller, I might just try that out!

And as far as those louvers go, I was talking to our lead mold guy at work, he says it can be done, and it wouldn't be too hard!
