Known as the "quick release mechanism" in the manual.
As posted way back - in short make dummy wing spar roots (reaching about
six inches outside the fuselage). They could be made from the solid but
this is an unnecessary sawing burden so cut a pair of plywood templates
for each side (drawing round the real spars) and screw them either side
of spacer blocks where the pins go through. Drill them using the real
spars so you get a perfect replica. Then you can set up the wing bolt on
the dummy in line with the one in the fuselage (use an alignment tube).
Then place the dummy spar back against the main spar, drill the hole and
insert the bolt.
As a bonus you can use the dummy spars to make a "quad undercarriage" by
adding a couple of legs with golf cart wheels on the bottom. Great for
wheeling the fuselage in and out single handed, testing retraction etc.,
especially when there are tornados about !
