Since the Telemaster has considerable dihedral, I would make the wing in 3 pieces, a center section the width of the fuse (or wider if using rubber bands) with the usual dihedral bracing. Then attach the outer wing sections with 1/4" ID brass tubing and 1/4" OD music wire. The center section would need a removable hatch for access to t-nuts/bolts or however you decide to secure the sections. For an 8 foot wing, I would also add struts similar to a Cub. Keep in mind the extra hardware will add considerable weight. Some builders are now using carbon fibre rods with aluminum or fibreglass tubing. If you have some local builders with experience with 2 and 3 piece glider wings you might seek their assistance.

I recently began making all my tails removable. Parts required are a piece of 1/16 plywood cut to shape of the fuse stab area. Draw a centerline and drill 2 holes 3/16" for dowels, and 1 hole 1/8" for a 4-40 attachment bolt. A T-nut is glued into the smaller hole. Epoxy the fin to the ply plate, then drill thru the holes into the fin for dowels. (Before gluing anything, use the ply plate as a template to also drill holes down through the stab bearing area and the stab). The pictures below show the detail.. Use hand drills (pin vises) files, and a lot of patience, takes some precise work. Hope this helps.
