We are making carbon roof and clamp, be useful to anyone

The Oily Bits S1 Specific Topics
1

Just wondering if its something anyone would want?

Im hoping to have the mould made by the end of tomorrow for the roof clamp, once it cures ill be making a carbon clamp midweek, with that in mind would anyone else want one in carbon?

We will be making a start on the roof in a couple of weeks aswell, not sure on what it will way yet, but thinking around 3kg for a twin skin motorsport style one(ie all the internal bits the factory on has)

If anyone would be interested in either let me know as I dont really know anyone who sells them in carbon so might be useful people who want to save a bit of weight

Put me down for a roof clamp in Carbon - let me know how much etc
Would also be interested in the roof.

ok Andy, once the first one is made we can work out what all the materials cost and get everyone a price.

What size bolts do people run in there stock roof, the one I have runs M6 bolts, is that same on the original?

4

I think from memory the stock three bolts on an S2 are M10. The question I would ask is what are you screwing into in the roof. I have first hand experience of the roof coming off due to naively running the wrong fixings in the roof itself. I now use three 6" lengths of steel strip with a bolt welded to it to spred the load, then sickaflex that in between the inner and outer roof skins.

i love sikaflex for this job.

Well the guy I bought the bodywork from said he used big head bonding nuts which are basically nuts with big repair washers stuck to them, he supplies the same roofs to maidstone on there cars, has there been any incidents with those guys loosing there roofs?

I was thinking of doing the same thing(big heads) but im trying to work out from what people are telling me is it the roof or the clamp that fails under load as no point re-enforcing the wrong one, wayne mentioned clamp on seloc and you mention roof.

M10 is a fair old bolt, alot bigger than whats on the s1, im guessing maybe they learned from problems they were having on the elise motorsport s1?

Any more news of these?

Just bumping again - did this die a death or move forward?

9

I’d still be interested too

10

Didn’t quo also have a scary roof moment too?

11

Well I made the carbon clamp, that came out fine, even added a layer of kevlar on the inside(i made it in the house) and its on my car now, got the mold at my mates house.

I still need to make the roof but due to the size of it i need to wait till we move into the unit so it can be kept warm while it goes off, doing it in a cold windy garage will just make it messy.

I need to get it done as it will only weigh 3kg and will help save 5kg off my car in a high place

Quo’s roof was our fault, it bent the retaining brackets back at little and lifted about 2 inches at the front.

Was going quite quickly at the time though!!! :smiley:

13

Any thoughts on pricing?

Be interested in a carbon clamp. Already have a carbon roof which is a lot light than the original fibre glass roof.

15

I will have a chat with my friend as he kept a record of all the materials we used, we went a bit overboard with mine and it has 14 layers of carbon and a layer of kevlar after everyone giving me horror stories about roofs blowing off, ive only taken the car up to 130mph so I wouldnt know what they are like strength wise above that.

I would imagine we would probably use 6 layers of carbon if we were making some more
