Re: [CAD_CAM_EDM_DRO] Air spindles

Thanks Brian and Ballendo, that's given me food for thought, althought where
you find air tools of any type for $20 I don't know - they are much more
expensive over here. Perhaps they add on the cost of shipping from the US??

I've just watched the 'World Championship' Scrapheap Challenge (Junkyard
Wars) program between teams from the UK and the US - I won't say more or
comment on the techniques used for solving the problem.........;o)
