here is a few pics of two wagons I have in the process for my son 'Diesel' and my niece 'Haley'. They have custom made frames with radius bar style front axles. the axles are 3/4 inch alum. I'm still working on the springs, so far I have found that the mainsprings from 8 day clocks seem to be strong enough while having alot of spring to them. I am planning on painting them like 60's dragsters with scallops and goldleaf lettering. Haley's will be called 'Haley's comet' of coarse, still thinking of a good name for Diesel's. Anybody got any good ideas for what would make a good scale alum. MOON tank?
