Yes - I'm no machinist so I don't know if it is strong enough for making the
axle, but mind steel should'nt be a problem.

If you use ISO 451 wheels the radius should be around 260mm - My Python has
a wheel radius of ~338mm. That gives 78mm lower free height than mine which
is around 14cm. It would be possible to raise the lowest points around 20mm
without too much hassle. It's not optimal, but it's sure nice that the bike
is easy to separate.

I think it would work, as rear forks often have this solution. The turning
force at the link is strong, so the steering would not be (very) affected.
On a DF bike the steering must be very smooth (but then again, My daughters
first bike has nylon bushings at the headset).

I have 5 in the shed, but they don't get the exercise they need :-( The
Danish HPV club have ~400 members.
Feel free to join our monthly trips, the next one is next Sunday the first
of August. Mail me offline if you are interested. We ride from 50 to 70 km.
