God what a trip down memory lane, last time I saw one of those in action must be 45 plus years ago in a small machine in Luton.

Thank goodness that cnc put an end to standing for hours using a "Tree" boring head. I gave mine away.

Nevertheless an ingenious piece of mechanism, see "Japan USA Precision Tools" website for cut away drawings and parts list. It took me about half an hour to work out what was going on inside. Production of new units and spare parts was due to re-start last month at JUPT in California. Due to lack of need, cash and a suitable host machine I won't be buying one this year ($3000 a shot !).
