need to Cover Blind Compartments, Voids... so
I had some lightweight galvanised angle
laying around.. as you do... and figured it would suit. I tried
two mehods of preventing the epoxy from sticking to the metal,
using plastic packing tape and black builders plastic. It came
off better with the black plastic but had the smoother finish
with the tape. Take your pick. I tried with and without the peel
ply. I figured on snading the surface anyway so gave the peel
ply a miss after the first go.
So, wet the tape and lay it in and use
whatever you can to clamp the two angles together to make a tape
When the tape has gone firm but still
green, use your box knife to trim off those deadly sharp edges.
But keep in mind that the epoxy will
take days to go off properly so store the extracted angles where
they will keep their shape. I stuck some in a shed while green
and when I went to use them they were twisted up. They still
I cut to size and mix up a glue and
apply plenty and screw the parts in place (short screws that
DO NOT penetrate the panels).
Later, after cutting out the flick
up rudder sections and installing the inner bulkheads, I put
two coats of epoxy on the inside of the duflex panels to seal them, at the right time of day...
and take that opportunity to also extract the screws and fill
the holes. Then installed the other angles and a peice of timber
laminated in place and sanded to correct angle. When ready to
cover with a panel, a generous mix of glue-bogg applied to the
parts and a weight on top to even it all out and you are ready
to tape the upper panels edge.
