One of the most satisfying aspects of building
your own plane is the overcoming of challenges that will seemingly
arise at every turn. I had developed a neat little turning jig
but couldn't turn the fuselage in the garage because of the height of
the tail and width of the horizontal stabilizer. The main spars
would also hit the ground during the turning process. Add to that
the overall length was a problem with my garage and a new challenge was
at hand. I decided I needed to be able to move the fuselage out
of the garage to accomplish the turn. I also wanted to reverse
the direction to allow more working room. Below are photos
showing my crude but very workable solutions. |

The solution was two carts with ends constructed to hold
my turning jigs. Each cart is a 2' by 4' wooden form with a 3/4
inch top and large castering lockable wheels. This allows the
carts to be locked in place or moved in any direction. When placed as
shown they only take a couple of inches of space beyond the length of
the fuselage. |
I knew the fuselage would need to be raised quite a bit to
clear the main spar as well as the vertical and horizontal stabilizer.
The jigs were designed to be jacked up, locked in place and
lowered when needed. The photo above shows how much the tail
needed to be raised. I used a wide board and a cushion from some
lawn chairs to pad the contact with the fuselage and spread the load.
PS: I placed a few sand bags
on the carts when not tied together to make sure they could not flip
over.

When not rotating the Fuselage, the two 2x4's
seen in the photos above and below are usedto ti e the two carts
together so they move as one unit. When the wheels are not
locked, the unit can easily be moved around by one person. In
fact, the entire turning operation was performed by myself with my wife
watching for clearance problems. The great part is that once the
plane in on the gear the carts and jigs will work equally well for
handling the wings. They were also both cheap and quite easy to
construct. I can also see many long term uses for them. |
