Ok, you fiberglass types. I need some
guidance. I can (and have) slapped resin on glass cloth and obtained a
functional (if heavy) item. However, I am about to start work on my new
radiator ducts and I would like to do better. My ducts will be
approx. 4"x4" at the inlet and approx. 9"x10" at the core. There might be
as much as 1 psi pressure on the walls (if I should ever be so lucky to go that
fast).
There a some semi compound curves at the corners of
the duct as it slopes inward from the top and bottom from the core to the
inlet.
I need your recommendation about the weight and
weave of the cloth. I have previously used the cloth tape as it was easy
to manage, but it required several layers and it is a bit heavy. Like I
said functional but not pretty nor light.
I would like your guidance on how best to apply the
sheet to the mold. In the past, I basically wrap the foam mold in duct tape
and the lay resin on it followed by raps of the cloth tape and more
resine. I am told that using sheet rather than the tape and first laying
it out on aluminum foil to wet it and then cut it in sizes say to fit a side of
the 4 side foam mold with a bit for overlap with the adjacent sides was one way
to go.
Any suggestions would be appreciated.
