Gidday,
I am after advice on stiffening bulkheads in my tunnel, now that I have opened
it up at the top to gain access to finger brake shelf etc. Like all of us, I
have
blue foam coming out of my ears, but I've also used ply as a substrate here
and there, and I know about light weight composite substrates like Divinycell.
So, does anyone speak positively about using a specialised foam substrate
instead
of blue foam with BID either side, or should I just use ply, or is even
good old blue foam good enough??? I could always add an extra layer of BID for
the weaker the substrate.
I need two of these bulkheads, one going across the tunnel from floor to roof
of tunnel at the level of the vertical face of the thigh support, and a forward
bulkhead just aft of the tunnel firewall. All help gratefully accepted.
