Battery Support Construction
6/25/06- Since I am
installing a heavy engine (IO-540), the plans say to mount the
battery tray behind the rear seat. My battery is a Concorde RG
25XC, so I made a mock-up of the battery box out of cheap Masonite,
which measures 8.5W X 6.0D X 7.8H and then designed the battery tray
to fit it. I'm going to make the real battery box out of
aluminum. The battery box mock-up will help me locate the
battery tray properly behind the rear seat back.
6/25/06- The battery
tray measures 9.75 X 7.125 and is made of 5/8x.035 tubing and .050
plate welded in the bottom corners to support the box. This
picture shows the bottom view of the tray.
6/26/06- I rigged up
a jig out of notched 1x2's and stacked 2x4's to hold the battery
tray level at 17" as indicated in the plans. I also clamped
the tray to the 2x4's to keep it from moving while I notched the
tubing to attach it to the fuse structure.
6/26/06- I notched
and tacked the 2 horizontal tubes first.
6/26/06- Then I
notched and tacked the vertical support tubes.
6/26/06- All the
structure clears the mocked up battery box by 1/2". The
battery box can be easily removed for service through the seat back
structure.
6/26/06- The tray
came out level with the upper longerons per the plans.
