Karl,
After. Check your back issues of Kfactor. Dec 2006 has an article I wrote on it. You leave a wire in the core before sheeting and then heat it up after sheeting to cut the cone.

Lance,
Is your process done before or after skinning ?
Karl.

Karl,
My answer might surprise you. When I have need to core my foam cores I core them from root to tip so the foam surface is in full contact with the skins. My wings were of interest to several people at the Nats to see how this works, but the local guys are used to my weirdness. This approach produces a wing with no soft spots on the surface.

Lance,
Do you apply the glue to the skins or to the foam core in case of a
cored (with cut-outs for weight saving) foam core. I thought that the
amount of glue spread on the skins in the areas that do not make
contact with the foam would be unnecessary weight. It will strengthen
the skin some.

Foam roller, my friend. a squeegee will force resin into the pores and away from the joint. Only a roller applied fast and light can meter the material properly and keep in on the surface.

To skin a foam core with contest grade balsa does anyone have a preferred way to determine when the amount of epoxy applied is adequate - using Easy Lam epoxy. I have been reluctant to use a squeegie, afraid of scoring the balsa. Would appreciate any comments. Nat
