I watched your video and got some great tips for making forged carbon. I was having a really hard time releasing types. However, when I compressed the cling wrap I use in the kitchen by putting it in a mold, I was able to release it surprisingly smoothly. No tools were required and it could be opened by hand. I believe this is the smoothest method.
If you wrap the aluminum insert with fiberglass veil cloth, there's far less likelihood for corrosion. Also, why not knurl the insert before you cast it?
First of all Congratulations for the great work. Just one thing. You mention on the video that you used 62g of fiber and 80g of resin. Resin should be around 40% in weight but you seem to have used much more. Is it because the rest got wasted leaking from the mould during compression?
I think around $200AUD but this was for larger quantities than was needed for one casting. I suspect costs could be reduced if smaller quantity enough for one cast.
