Made some molds for running boards and stock width early bumpers over last week or so, and made the actual parts now, was ok to take the running boards out today and gave one a basic trim just to see the weight, for reference 1st pic is genuine VW running board, next is an older pattern version then the carbon version Grin Shocked Cool

Hmm,
I seem to be spending far too much money recently...
Shame to cover the carbon BUT if they were then coated in that 'plastic' chrome stuff youd be able to keep the look of bumpers but with the weight saving of nerf bars...  Cool

Cool stuff! If running board mould be taken with the rubber but without the aluminium list you could just paint it flat black or use rubber dip paint lightly to achieve stock look using stock alu strip on the side. Or just replicate the stock narrow and wide mouldings in carbon and paint it using aluminium/chrome paint. 🤔😁

Hi Richie

Well done on the carbon fibre parts, the finish looks really good.

For your reference, I've had carbon running boards for a few years, purchased from CSP. I got one out of the loft earlier and weighed it as a comparison. Sorry, no digital scales available.

[ Attachment: You are not allowed to view attachments ]

Just over 400grams. So good job on getting the weight down even more. You can see light through these in places they are so thin  Cheesy

Also, this label is within the weave on the underside, anyone your familiar with ?

Thanks, good reference there for my weight aims, mine are really strong and thick still, no chance to see through them, probably strong enough to stand on once bolted to car I think, yours look like they are hand laid which if so will always be heavier even with less carbon layeys

cheers Richie

You're getting good at this!  Cheesy I saw the photos of the old bonnet deforming at speed (maybe on Faceache? Deleted my profile on there now, couldn't be doing with it!) and it looked quite alarming! Have you built any ribs in the back to strengthen it up, or just relying on the material properties and VWs design?

Just relying on the carbon strength with a core material as well as factory pressings, in a simple test fiberglass bonnet deformed on the big top areas with 7kg weight[lead bar] on it and this doesn't deform with 25kg on it in same place[that was all lead bar i had around Grin

This is the picture Neil mentioned that provoked me to make the carbon bonnet, you can see the fiberglass version collapsing on the top area and this is only at 130mph so going 170 who know how bad it is Shocked

That looks like some serious elastic deformation on the bonnet. Sorry for asking, but didn't you also have any issues with ground cleance to your bumper brackets at the higher speed?  Shocked

Ps. The carbon fibre parts you made look really good!

Another small saving, factory steel light housings weigh 244g each side, these carbon ones i made 54g, and i will use led lights inside which save another 60g over the normal steel bulb holder and bulbs each side Smiley

Richie, I do not know what or how to "beat you" right now. Gasoline refill door in CF?
Replace the roof?
Make a full CF VW tub beetle? That would be cool!  Roll Eyes
I guess I should start by installing my doors and the missing rear bumper too.

Anyway, these are two pictures from my workplace. Maybe a CF wheel for our beetles? Naw, price would be silly just to do the tools needed.
I am practical guy and my only formal title is Composite Engineer (diploma from the early 80īs) but I am neither very skilled or have any practice on the topic doing the CF parts myself. So buying the parts is expensive.
But dreaming is fun!
