Today I have fixed in the the support tube slaves TP5 and TP6. they where fist prepared by cutting small groves in them with a hacksaw then sanded to make a good bond area. I now fixed them in to the inboard tailplane with rapid epoxy, held in position with the toque tube. Later I cut and shaped the plywood ribs to fit the ribs, all ready now to be lay-ed up with 4 ply's of bid to make a very strong rib.
