After the discussion about bowing doors and the need for a pin to prevent
it, I decided to stiffen the door by laying carbon fibre strips in side of
the door and epoxying them in. The strips were laid in a horizontal plane
along the bottom of the door. I completed one door first and then found
that it was significantly stiffer than the other. I am hoping that this
will be sufficient and that I won't have to retrofit a third pin.
I am still wiring. Will it ever end?
