REFLECTOR:Firewall penetrations (was Control Cables)

[KeithHallsten]

I'm just starting on running the cables, tubes and hoses, so I'm not yet
sure how much stuff I will have coming out of the ducts.  Since I'm building
a fixed-gear XL, I have the option of running quite a bit of stuff down the
keel - some of it will then go through the firewall instead of out the duct
openings.  My vague intent is to wrap the wires and tubes with cut-up pieces
of firesleeve at duct openings, then fill the remaining spaces with fire
putty (or some such material) and cover it with SS sheet.  It's also
possible that I may end up using one of the larger pass-through fittings
from EPM-AV Corp mounted to the SS sheet covering the duct openings.  We
will see how this works out in practice!
