Karl,

You are absolutely right.

Mark,

I have found that it is very hard to get more than 1 oz. out of each 
panel on a 2m  pattern wing.
I have seen this method done in Europe a number of years ago.
It is a lot faster, once you have the right setup, than cutting out all 
the little squares or diamond shapes. 

Karl.

I second that motion!  This is a great way to take about an ounce of foam out of each core.

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
