Fancy bolts

Sometimes I wonder why planes can't be as mechanically simple as my bicycle, but I think I know the reason for that!  Today I spent many hours bolting the disk brakes & associated bits onto the main legs and then quite a long time fiddling around to fit the main legs onto the underside of the plane, at which point they become the undercarriage.  This was a pretty short day's work, but it really looks like we've achieved something.
