On to the more gooder stuff.
The neighbors were giving me funny looks while I was building my vacuum pump assembly thingie. For the final parts I’ll be using the vacuum infusion process to wet the carbon fiber with resin which is supposed to give the best carbon to resin ratio for the lightest weight, aside from using prepeg carbon in an autoclave. The carbon is laid into the part, flow mesh (green stuff) over the carbon, then peel ply which helps remove the flow mesh from the carbon, and then the vacuum bag material (redish stuff). The yellow stuff is sticky goo tape that seals everything. The resin is pulled from one side to the other with a vacuum pump and then held at max vacuum for 4-5 hours while the resin cures. I made my own degassing chamber to remove the bubbles from the resin. My wife asked if I’d see her missing cooking pot, NOPE! I used a rubber tire tube to seal against some scrap plastic from the plastic store. Not all resin can be used for this type of process. It has to be of thin consistency. You may be able to get away with normal stuff on smaller parts, but I have not tired it yet.
This was my first try. I decided to make a flat undertail piece and did some small scraps to test thickness.
