Same here. I was impressed with how well it worked. No leaks at all. And it was really easy.

When I was building my F20 wings, I made a nice vac bag with some heavy plastic, sealed the edges ( i thought) etc, but the damn thing leaked like a sieve. So threw it into a bin bag, taped it up and it worked perfect, like you found out. I do like those snap on seals from offtheedge tho. Very convenient.

So you're going with a bladder on this one Jordan? Did you use a bladder on the F-20's?

Yeah I'm using a bladder. Gonna try clamping the moulds in a vac bag this time round. We'll see how that works out Last time I used a bladder was on my twisty wing fuse moulds. Fantastic seam even just using 10psi. Way better than hand rolling it. The F-104 is hand seamed, I wasn't keen to tackle a bladder with fin, intakes, fillets, etc. But it's a lot of work involved doing the layup and seaming. One of the main aims with this L-39 was to make the layup as simple as possible.

Yeah, it's cool that you can get such a pro seem that's actually stronger than the rest of the fuse. I'll wait to hear how easy the layup went but I'll be crossing my fingers

Oh yeah another thing I want to try is laying dyed silk into the moulds for colour.
Something like this

I hope you'd make that show on the outside and keep the inside nice and dark because if it's on the inside it'll drive you nuts during layup. I haven't done many layups but the mold used to lay up P-40's had light and dark patches and it kept looking like there were bubbles in the glass.

Yeah it will be an interesting experiment. I freakin hate laying up carbon for the same reason. So hard to tell if there are bubbles.

If it doesn't work then I'll just get Tammy to make me a kaftan with the leftovers

Silicon inserts? I've done a fuse with a small fin which comes out ok.

Looking forward to seeing the vac bag trick.

Not sure what the advantage is. But if the outside bag loses suction, you'll have a big mess on your hand courtesy of the inside bag!!!!
