This link will give you some idea and give you some names of folks who do this kind of construction. Bob Hunt has a video on it, as does Al Rabe.

In my case, I was building a Dmeco Sportwing for CL Old time Stunt. The plans call for a solid shaped symmetrical leading edge with 1 inch wide 1/16 sheeting behind top and bottom. I carved a form out if a balsa stick. I wrapped the stick with saran wrap. I cut pieces of A-grain 1/32 sheet to size. sprayed some water and a spritz simple green on my glass building table and washed the 1/32 around in it, turned the sheets over and did some more. The sheets got limp in a minute or so. Wrapped them (two sheets, i. e. two layers) around the form and held them down with ace bandage. After they dried, I took them off and applid slightly thinnned down tite bond between them and rewrapped them. After competely dried, I cut the ends to exact size and glued them to the wing framework with CA. Then I made a vertical 1/16 sheet web to make a D-tube. Worked nice and looked like the original construction when covered. I was real pleased and surprised at how easy it was to do. Next time I will do the gluing as part of the first molding.
