Some of you will know whats happening here...

When casting things with beads it's easy for resin to accumulate in the corners and weighs alot more. Outward shapes are great as you can rake it onto the offcuts. The front quarters only have two layers of 200g so will be quite flexible, however the bonding is only 4 inches apart so it's ok.

Also on some parts I've allowed for a layer with unsoiled offcuts. It's easy to think they're not worth anything....

..Also will clean the busbars and do 0-60, when I get round to it

More bits. The marks on the finished piece are where the carbon is folded in the post

The temp has dropped and the first two pieces have gone in the oven, if you do that remember to open the windows as it kind of burns your lungs. They dried in half hour though

In between the first and second sheet theres offcuts from the hatch section. The guy from autoglass said he would'nt remove any windows because he said 4 out of 5 times the glass breaks but well maybe I was lucky, all 6 no breaks. Handy because the hatch one is toyota only £350!!

I found if you use a saw on the vertical bits then a thin chisel or sharpened steel on the other parts....

Best weigh in so far. The front quarters, glass 390g, carbon 12g. Two layers of 200g plain and I did spend alot of time removing as much resin as possible. over about an 8" spread I would suggest going up to 3 layers..and so on. For non structural..

Thanks..so, this is the trickiest bit so far....

Theres no easy way to lighten any parts of the original mirrors. A weigh in of 1.05kg including bracket. It's injection moulded and has electric motors. If I mess with it I will have to use my arms to adjust it in the future... ....

Quite a commitment but here goes

Nathan jones · 06-15-2019, 12:52 AM

For the smaller parts I would recommend a lighter grade cf but it just folded around the tighter corners. It's not quite cured yet but has an initial set so...

Also the brackets were entirely made from offcuts, not nice looking but effectively free
