I was hoping someone could review my measurements before I start putting the drill to the fuselage.
The way I did the setup was by having two equal length pieces of 4 foot aluminum angle, that were clamped together and mirrored drilled for the axel bolt holes and then two holes 23 inches from centre fore and aft. Both gear had the holes in exactly the same location.
I copied Matt Dralle's use of a square sheet of plywood that fit in between the two angles, which kept the gear parallel to each other.
Of course the fuselage was leveled lateral and longitudinally, with the levels being located at the F-822 bottom skin.
6 plumb bobs in total were dropped.
I struck a centre line from the tail wheel mount centre holes and the firewall centre. The line was stretched, marked and tapped to the floor. The plumb bobs were dropped and measurements taken. The rear measurement wasn't taken from the rear plumb bob as I couldn't get around the saw horse, so I moved the line forward of the horse.
To my surprise, the measurements were pretty good after a little adjustment. The rear plumb bobs (C & D) to the rear centre line mark was out 1/16 of an inch and the to the forward centre line mark was out 3/32 of an inch.
Any comments or suggestions appreciated.
