Spot on. The trouble is that it doesn't really come apart under normal use,
and even when loaded with a kilo it is only a little bit, but still
together, if you know what I mean. The axle does keep the two pieces clamped
together, but also makes it harder to turn the turntable from the increased
friction resulting in a jerky movement I don't like. So I just loosen it
off, but it is there just in case. I think with a Beat Felber roller thrust
bearing this increased friction would not have such a negative effect.

A jib would be nice, but to be honest I think the model is now done and it
is time for a code freeze - perhaps on the next crane. A ballast trailer
would also be good, but they are illegal in the UK as mobile cranes are not
permitted to tow trailers here!
