RE: making a mold
Tim
Pretty close to what I did on my last 104 fuse. But I never liked the tape on 1/2 mold.
Since the 104 mold has a pretty good sized opening in the tail section, I close the mold loosely,(.25 mm gap maybe) then I put a wet tape/bead of cabosil on a stick and place it in the fuse. Press the tape down with an acid brush on a stick, then fully clamp the mold. A lighter tape I use in the Vstab. The cabosil mix we put in a paper mini grout bag made from the pages of AMA magazines to apply.
Vac bag. I have never done since in my applications is not worth the extra materials. Not even in my composite wings.
