Hard top - northampton

Post by Astie » Thu Oct 04, 2018 1:13 pm

Background: I work for a composites company and I'm doing some business development work. We are looking into making a carbon fibre hardtop.

This may be a big ask, but does anyone have a hardtop in northamptonshire area I can have a look at? And take a few photos of the details.

Thanks in advance

That was quick! :)
OP is the plan to make several? Or you just fishing for viability at the moment?

Will you make carbon or glass ones ?
I’m in Brackley and would be up for taking a look at what you propose.
Cheers

It all depends on market demand, have to look at the figures. Going to have a look at one tomorrow. Hopefully have a proposal next week to see what interest there would be.

I think there’s potential for a decent sized market on here alone if the price is right of course.

I’ll be following with interest.

Anyone else feel a group buy coming on in the future? :D

As with anything, if there's enough demand I'm sure it will drive production costs down?
I wonder if the OP went to see Squadron Leader's hardtop? It's been a while?

I’m interested. What’s the durability of carbon fibre on a car that’s not garaged?

The hardest part of the project would be the closing mechanism, as we would have to design and manufacture this. Unless anyone knows of an off the shelf solution?

For a run of 30 we would need to sell them at £1600 each.

We would use UV resistant resin, but it never really is. We would also lacquer the top to improve longevity.

Still interested?

It's not possible to replicate the existing mechanism on the OEM hardtop?

Would the internal be lined similar to the OEM?

If it were closer to £1000 you'd have these flying out.

Lining with foam backed fabric.

we would use the existing mechanism as a basis, but we would still have to put the design through our internal certification process.
