here is an image of my barrel cart - this is the type of wheel and axel that is underneath the spokes have to be rather heavy because of the weight they have to carry.the wood rim has to be thicker. - there are also springs for the cart you are drawing because the organ is very heavy. i do not have an image at the moment - will look for one - it is a packet of slightly bent metal strips that get smaller - sorry don't know the english term - have to look that up too.

as for the figures, dv mentioned somewhere a way to do it some time ago - he explained it to boofy - that would be the best way to do it - these figures are in comparison very small so it would look good anyway.
