Nice looking progress John!
I used Stan's technique for the oxygen hose, don't know the exact guage wire I used, pretty much went with the "TLAR" method!
Ran into a little snag with the Hasegawa cockpit. The Oxygen regulator's mounting point places it almost directly on the floor, leaving no room for the pilot's supply hose to exit from the bottom. Also, Hasegawa molds a little box for the guages to fit into, and the instructions show them properly angled upwards slightly, but molded the mounting lug so that the guages actually point down to the floor (the photo shows mounted how Hasegawa intends them to be). Not a big deal, just need to relocate the mounting points to raise the regulator off of the floor to make room for the hose, and relocate the guages so that they face properly.
Stan- I have seen photos of a restored cockpit with the hose being what appears to be a simple rubber hose. It's end is usually hanging in a bracket mounted on the sidewall. I don't see room to put a bracket in the kit cockpit, and I see you mounted yours hanging on the fuel line. DOn't know if that would work on the 1/32 kit cokpit. Any other ideas how to mount it's end?
