thanks edspedalcars....its taking shape..i think its quite important to conceptualize before construction and run by the roof of your pants when a disaster design wise happens.As long as you can think outside the box
but within the frame work of a good working model as far as function goes then it should be all ok in the end.famous last words....ive tried to think ahead of time ie...where the chain flows from and too etc etc etc....
If it all turns to custard and ive had a battle of waterloo and its a complete flop then at least it will make good fire wood...though very expensive firewood.
