Hi paul,saw this in the paper tonight,looks interesting,heard of this iron drive system that has only the trust of a piece of A4 paper resting on your hand,but not the proplusion system thats on tonight, paul you came up with it so you can take the credit four it,how do you feel peter about a off topic area,as long as everyone keeps it faily? clean,or do you think it would upset the real reason we are all on this site, Regards, Dale.
