Hi All
I have to thank Matt for his guidance and assistance with my various projects over the last six months or so, I would not have managed without your  help along with this website.
Up to this point I have moulded my own Carbon sheet using various thickness of "Soric" to produce truly professional finished Carbon sheet which I have used in building various Tri's Quad's and Hexacopters, I have also made Canopies used to cover the fragile electronic components, all of which have used the vacuum resin infusion technique.
Now I am going for the totally moulded Quad, 500mm between motors, consisting of a top and a bottom moulded shell, with internal (own made carbon plates).
Up to this point I have used the high density polyurethane foam block as a core to build a pattern, this has now been covered with one layer of 163g woven glass cloth, I will add another layer once this is cured (not sure if I should have used two layers up front).
I have attached a photo of progress of the pattern, I intend to use the pattern to make internal moulds (guided again by Carbon Mods) which I will mould Carbon Fibre shells that house all equipment and hopefully will fly.

I will try to let you know how I go on along the way.

Hi
I have made a new set of moulds and have tried a couple of times to get a decent part moulded from these.
I am having problem with my technique for avoiding "bridging" so I am still experimenting with this, I have tried tacking the dry carbon down with a mixture of meths and resin, which I had some success with, but then went back to loading the cloth in dry, which, now that I know what I am doing wrong is turning out better, but I slipped up on mixing my resin correctly, so the last one did not cure.
The last couple of parts I tried, I did not use any infusion mesh (which I struggle with) the bottom part was OK, this had Soric between two layers of carbon and infused OK, the top part did not infuse correctly I only used 3 layers of carbon and this did not draw the resin in.
I have been talking to the guys at Carbon Mods who have kept me on track with there knowledge, otherwise I may have given up, I am on holiday for a week then work commitments will take up the majority of my time so it could be a while before I can continue, But I will keep you posted on my progress.
See attached pics of the new moulds.

Cheers
John
