The plan is to run this bike without a battery, but if this proves to
be too much of a hassle to start it we wanted a place where
we could hide a tiny Antigravity battery. In any case we also
needed a spot for the ignition switch, so we decided to make
a "hidden" compartment under the seat.
Starting with a cardboard template we transferred that to MDF, radiussed
the edges of the MDF piece, made a Delrin die to round the edges
of the hole. The Delrin die was pushed into the aluminium under
the press, the outer edges of the electrics tray were hammerformed
around the MDF piece.
Aad welded 3 little threaded bungs on the inside of the tray, while I
made some steel mounting tabs that would be welded to the frame.
No mounts or wiring will be visible after assembly. We clamped
some pieces of scap iron to the frame tubes to make sure the
tray would line up exactly with the bottom of the frame tubes.
