    Homemade CFRP mid engine sports car

    Plan A is still some form of V8 crate engine and whatever suitable transaxle i can find to mate it to But .... occasionally i dream about V10s and V12s, i even think they would fit. I'm very wary of the fact that this is going to be a slow build and the world is changing, so am holding off on...

    Got two seats in now ! and they successfully passed rigorous testing by my little helpers. Am fabricating my suspension uprights right now, will post some photos of them soon, and in the background am thinking about the steering and IP.

    Homemade CFRP mid engine sports car

    got the first seat in, aside from an annoying problem from a spinning rivnut it went pretty easy. First i got the seat sitting at the correct position and angle. This was done by first sorting a bracket to the rear bulkhead to set the max longitudinal position (not fixed yet just resting...

    Finished off the seat mould and made my first seat, after trimming the edges it mostly fits in the car - phew ! Next I need to make some brackets to mount it to the tub. I'm going for a fixed seat and adjustable pedals. I also need to sort the seatbelt anchorages, i'm going for a 6 point...

    Homemade CFRP mid engine sports car

    Thanks Neil, agree with you 100%. Computer analysis is my day job so this is something i'm comfortable with, in fact its a little bit one of the reasons behind my build - I spend all day developing cars only in the virtual world so this is my chance to satisfy my desire to get my hands dirty...

For the seats i need to make my own because off the shelf...

    Homemade CFRP mid engine sports car

    Thanks for the words of support guys i have been reading Alexanders VW W12 thread with fascination .. and recently watched someone on youtube restore an M120 V12 which got me dreaming. I'm wary of being caught out by any changes in UK IVA rules (given this is going to be a slow build) so trying...

    Homemade CFRP mid engine sports car

    Well my goal for 2023 was to get some doors on and i just made it ! I even had a spare couple of weeks to get the front bodywork on as well The doors are pretty well set now, just need to build up some material in a few places on the door inner flange to make a tight contact to the seal. Since...

    Homemade CFRP mid engine sports car

    Thanks Ian, the gas strut mostly sits between the windscreen surround structure the door frame section (next to the seal bulb), it doesn't really protrude much below these for head to strike .. but having said that there's not a lot of general head space between head and roof which has always...

    Homemade CFRP mid engine sports car

    Still tinkering with doors, the LH one is nearing completion now Sealing; I fitted a flange around the door aperture for the seal. Once in place I 3d printed some little clips that clip onto the flange and mark out the exact offset i need for the seal to make contact with the door panel. Then I...

    Homemade CFRP mid engine sports car

    progress update .. been busy having fun with doors ! I've moulded both doors and today did a first test fit on the car with the LH one. So far so good. Not tried to properly align it yet, but expect some challenges with gaps and flushness ! One both sides are on and aligned I will next sort...

    Homemade CFRP mid engine sports car

    Hi Michel, the dampers are very close to horizontal, there is some downward load but calcs show the crossmembers should be fine for bending I've been working on the rear wishbones as they are small enough to bag up and take indoors to cure in this cold weather, finished them all now. Thankfully...

    Homemade CFRP mid engine sports car

    Feb update, been working on the some of the rear chassis parts. Three out of the four rear wishbones are done - more on those later, and finished the rear cross-members that the rear dampers mount to. These are wet layup cfrp with a high temperature resistant resin, again I used a 3d printed...

    Homemade CFRP mid engine sports car

    Mesa that's not a bad idea, i'll look into that. Depends a bit on choice of powertrain. The large openings were mainly for aesthetic reasons, not practical ones (gives nice view of the headers which i like). Jim - no I bought those tubes pre made, I got them from https://www.easycomposites.co.uk/

    Homemade CFRP mid engine sports car

    Thanks Joel, David - i don't find laying up with it itchy, but the dust from cutting or sanding can be. I do find that the fibres get everywhere though which is a pain. Jim - The larger parts are made using vacuum infusion. Dry material goes in, vac'd down, then resin is pulled in and under the...

    Homemade CFRP mid engine sports car

    Thanks Michel ! progress update, finished the flanges between rear bulkhead and floor/sill on the cabin side. As these will be somewhat visible I moulded real parts and bonded & riveted them in. I find my 3d printer is great at quickly making small moulds. On the other side (engine bay side)...

    Homemade CFRP mid engine sports car

    Fitted the rear bulkhead panel, just needs a bit more flanging around the sills to be moulded and attached. Me and the kids have enjoyed sitting in it this afternoon making broom broom noises.
