Although I am very new to the art of laying up fuses (3 to date), your frustration is very fresh in my mind. I decided that a thin layer of thick epoxy between the mold and the first layer of glass should work. It did. A thin layer means, very thin in order to minimize weight build up. I determined that nearly half the weight of a TD fuse is epoxy. Thick epoxy means as thick as the squeeze mayonnaise (which is thicker than the squeeze catsup or mustard). It takes about two or three passes with the acid brush to spread the epoxy/cabosil thin enough. I also rake up the extra epoxy as I go back over the mold during the second/third pass. This works (I think) because the epoxy holds the glass to the mold sides. Also, the epoxy doesn't slide down into a puddle.

Mikey, try laying the cloth at 45 deg. as it tends to follow the contours much better.

[RCSE] Airless hand layups in molds
Hi I'm having a heck of time getting all the air bubbles out of my part layups. Any suggestions? My problem seems to be consistent around 90 degree bends (Around the wing saddle), I have been able to mix a bit of cabasol to create a sort of fillet, but with this method I have to wait for the surface coat to cure before laying down my glass. This makes for a 2 session process. The hot shots I talk to, tend to do a layup in one session. I have heard that by slightly heating the mold can help reduce air bubbles. I am using 1.5oz cloth followed by two 3oz cloth (Powered Aircraft). I can provide more info if need be? Mr Frustrated RCSE-List facilities provided by Model Airplane News.
