Bob and I bolted the gear on and torqued them down then installed the wheels. The fuse was up on a couple of steel saw horses while doing this and JUST as the last wheel was slid in place the fuselage settled onto the wheels. I looked over, wondering why he had lowered it and he was looking at me with the same disbelief....the saw horse folded! If it had done so 5 seconds earlier the plane would have been sitting on it's brake caliper....I got lucky.
