Hi Thanks Bobbin, we had a miller very similar to yours, worked well, we chucked it out eventually and replaced it with a big beaver mill (£1500) off ebay. We have just installed 4 machines in a shipyard making bits for the new aircraft carriers, its hard to get an idea of the scale of the ships when you see the flat plate being cut, but they are going to be massive. We used to mend the old line following machines, there are still a few of the old BOC machines about with the original scanners, designed in the late 60's before servomotors were readily avaliable. The gearboxes were like a swiss watch, 6 watt motors I think, not bad for a half ton (1230lbs it says in the manual) machine, the rails had to be fairly level or the machine had difficulty dragging its self up the rail. Thanks for the good wishes.

Mike
