Mesa - Here's some snaps showing the process. First, make sure you have everything prepped. Once you start you'll have sticky hands and the clock will be ticking so I get all the plies cut out and counted, find a good movie to put on and open a beer all before the epoxy is mixed. step 2, mix the epoxy and paint it over the part, then apply the CF ply, then apply more resin, brush all over and place the next ply, etc. This evening I was putting down 5x plies of 200gsm UD all over, which gives me just over 1mm of CF. It took me two and a half hours to get all 5 plies down all over which is all the time I have before the resin starts to gel, so I'll need to repeat this activity several more times on other days. This is layer 2 of 5 layers that I will put down, theis UD sits at the middle of the stack. Once all plies down, I wrap in perforated release film, then in breather fabric. Any excess resin will bleed into this. Then into the vacuum bag to compress it down .. then check for air leaks .. this is the part I dread, at this stage i'm tired and I don't enjoy hunting for air leaks. Once airtight I clamp off and take the part inside the house to cure in the warm. Once cured i'll unwrap and tidy up the surface, sand off any resin flash between the crinkles in the release film and abrade the CF ready for the next layers to go down.
Once all structural plies are down, I sand the part smooth, any bad lumps I might use filler, then I stick a final cosmetic CF fabric over the top with spray adhesive. Then lots and lots of resin over the top, sand down the grits until ready to be polished to gloss.
This part I also need to drill and tap holes and insert helicoils. I use a 3D printed jig to align where to drill so I can find the Ali inserts embedded in the part OK.
