Cut Inspection Holes in underside of both wings for Lift Strut Bracket bolt access. This cutting action is, in fact, melting the Dacron fabric, paint and glue, using a hot soldering iron fitted with a pointed wood-burning tip. Temporarily attached the forward bracket to serve as a guide to locate the slot location for the aft bracket. Taped a steel piece to the Fabric to serve as a cutting guide for the hot iron tip. Width of the slot is determined by the penetration of the tapered tip. Melting the Dacron fabric, instead of cutting with a knife, leaves a fused edge to keep the fabric from fraying.
