You can do a leak down test on your bag before infusing to make sure you don't have leaks. Leave it 45 mins or so with both lines clamped off after pulling a vacuum (vacuum pump off) to make sure it doesn't leak air. Also, make sure you let the resin de-gas before adding it into the mix to avoid voids. Cool project. I have a Factory Five GTM, mid-engine with a manual trans is the way to go!
Thanks for the suggestions. I like the GTM and considered building one before making the decision to build my own design. You seem to have carbon fiber experience, I have a question. The parts I have made so far all have slight imperfections in them. I am spraying a gel coat down on my molds before I start but I am getting some small areas that I can feel the CF material, like there is no gel coat in those areas. Could I not be applying enough gel coat or is the epoxy dissolving the gel coat maybe? I know the entire mold had a gel coat and there were no void areas before the infusion process. Thoughts?
@@basementsupercarbuild2948 Make sure there are no air bubbles in your resin, that it has properly degassed and that the working temps in your garage are high enough. Thinner viscosity resins can help if it's an infusion problem. What are you using? I assume you are talking about applying resin to the molds before infusion for an outer finish. What times did you allow before infusion for the surface to cure?
@@carbonfiber8071 I am using the slowest curing epoxy that Soller Composites sells. I am using GC50 gel coat and letting it dry overnight. The recommended cure time on the gel coat is 3 hours and infuse the part before 24 hours. I will try a thicker gel coat next time and see if that helps.
looking good! Good job Roger
Thank you
Hey Roger, loving it, that carbon fibre looks great!
👍💪✌
Thanks 👍
Best of luck to you on the project looking forward on your progress
Thank you!

@@basementsupercarbuild2948 It may just not be enough thickness, experiment with a smaller mold until you get the results you want.

Great job:)

Hey roger I am considering doing something like this myself, how much has it costed you so far?
Right at 100K. I am guessing the finished car will cost about 125K. It’s not cheap!!
The twisting of the camera in your time-lapse is nauseating
I agree. The camera was on a stand and wasn’t moving. I’m not sure what was going on with the video, I cut out the worst parts.
