| Subject: | wheel jack fixture |
Unfortunately there is no source to buy this fixture, that I could find,
hence I made my own. It was easy enough to build, but someone with a CNC
shop could mass produce and sell them for profit. With 10,000 RVs
flying, most with round gear legs, there is certainly a market. As far
as needing two, you could get by with one. Just jack the first wheel
and then lower the axel onto a 4X4, remove the jack and raise the second
wheel. With the first wheel on the 4X4, I would make sure the wings are
tied down. I personally would service one wheel at a time though. To
build one, get some thick wall 4130, turn the inside of the large tube
to match the taper of the leg. This step is optional if you
don=99t have a lathe. Instead get tube that is slightly larger
than the legs, and wrap the leg with tape, with more wraps at the
bottom, to make the leg parallel. Next cut the tube for the bottle jack
head at the correct angle and use a mill, or file to match the outer
diameter and angle of the leg tube were it will attach. Size and weld a
thick washer to the inside of the bottle jack tube from the top, so that
the jack head has something to push on, and is captured snuggly into the
tube. This step assures the jack can=99t slip out of the fixture.
Weld the jack tube to the leg tube. Next fabricate the four bolt tubes
from again thick wall 4130, and weld them to the leg tube, making sure
they are all square to each other and the leg tube, otherwise it will be
difficult to get all the bolts through the lower half as an assembly.
After welding everything together, cut it all in half. Done!

For those not having welding or lathe, you can make something similar with
a couple 2X4 scraps. Just drill for a couple 1/4" bolts beyond the width of
the steel tube. Then measure gear leg and get a hole saw of right diameter.
Bolt the pieces together, run the hole saw through at the parting line, and
you are done. I did similar deal for flat steel gear legs for older Cessna.
Worked fine. I will be using wing jacks since I have had a pair for the 15
years I owned my Mooney and needed to jack it up for any gear work.
