Re: [CAD_CAM_EDM_DRO] Re: water jet

Dave,
I'm not sure how they add abrasive - premix it or push it after it
leaves the nozzle...
I think the whole nozzle can be purchased separately - will make a
search now...
But it seems to me that it would be much easier to implement for a DIY
guy then the laser.
I think people like you, with tools and experience, may give it a shot.
