Good! I'd only be too happy to know my work was useful to someone else! I really learnt a lot from this place.


I've always run our machines on tracks and I like it to stay that way - but having said that, it does not mean its superior to other types of drive. I actually think its got more disadvantages than advantages...mainly being: increased weight, complicated (more things to go wrong) and believe it or not , less traction! The main advantage is its ability to move over uneven surfaces, that is - it difficult to get stuck.

Thanks for the compliments on the drawings...but as I said, once you get used to it, its quite simple...will try to upload some of the components just in case someone would like to use them
