Once upon a time I owned a mono-wheel and flew almost 700 hours in this
configuration
before I saw the light and converted it to a tri-gear. (Bliss!)
Only once did I experience a flat tyre as a mono and was obliged to create a
jacking
piece. Tim Houlihan's article "International Rescue" in the December 2016
issue of The Europa Flyer brought the flat tyre incident back to mind.
My jacking piece didn't require any additional holes to be drilled in the
undercarriage
swinging arm. Considering the 4 bolt heads which attach the LG07 shock
absorber bottom plate to the swinging arm, cut a square from 3/16" steel plate
large enough to encompass all 4 bolt heads with a bit of a margin.
Drill 4 bolt holes in the square plate to match those in the undercarriage
swinging
arm. Enlarge the 2 upper holes in the plate enough to allow the bolt heads
through.
Weld onto the plate a metal pad of any design you think suitable for a trolley
jack to lift against. If you want to protect the paint on the swinging arm, glue
some thin soft material onto the face of the plate which contacts the swinging
arm. Job done!
When you want to jack the aircraft up, remove the two lower bolts from the LG07
shock absorber bottom plate and then attach the jacking piece to the swinging
arm with the same bolts. I used this device several times over the years to
change
tyres.
I'm still in one piece!
