I'm planning to build a crank organ cart and, before I unknowingly
make a huge design mistake, I'd like some ideas and hints into what
makes a good cart.

It seems like a brake of some kind would be a must to keep it
stationary while cranking.  Likewise a suspension of some sort but
again that would need to be disabled when cranking.

So, what should I include, what should I avoid, etc.?  Thanks!
