port flap layup

Port flap underside layup: 2001 12 04.

Canon F-1, Fujichrome Velvia 50.

Port flap with underside layup completed. At the far end of the layup table is the fan heater; at each corner of the table is a bracket where the frame of the curing tent plugs in. On the right-hand side of the table is the roll of peel-ply, covered with polyethylene sheet to keep it clean. It doesn't live in the heated cupboard with the glass cloth because it can fail to peel cleanly if kept too dry.

Removing TE support block

Flap TE support block removal: 2001 12 13.

Cutting the TE support block off the port flap. It's important not to cut into the airfoil profile forward of the piece being removed, so I use an offcut of sheet steel to prevent the hacksaw blade wandering in the wrong direction. Naturally, the edges and corners of the steel sheet were well rounded and smoothed to prevent it causing any damage as it is slid along under the hacksaw blade.

Flap in curing tent

Curing tent: 2001 12 21.

Canon F-1, Fujichrome Velvia 50.

Curing tent erected with port flap inside. The tent is made from 1 layer of builder's clear polyethylene sheet, taped onto end frames of 15mm copper water-pipe. The plastic is sagging a bit here because the heat is off, but when the fan-heater is running it tends to balloon up.
