nexts = nests. My bad on spelling. The nest fit the show side of
headliner and used
vacuum to hold the part to it, the cut lines had SS blast deflectors to

of the nest.

The portions of the profile that I had to dwell on to get a sharp corner
tended to have
their blast deflectors wear though soonest. At first we made new ones,
later we just
welded them up, quicker and easier.

Waterjet seems to have a lot of tricky, unanticipated issues. The early ones
were hellishly loud, and you had to wear hearing protection when you were in
the same room. Is that still true?


I watched a demonstration of an abrasive waterjet system cutting 1/8"
aluminum and the pump made some noise, but the cutting was under water
and did not make noise that I remember. The whole workpiece was under a
few inches of water that got pumped in before the cutting started and
pumped out to below the workpiece when done.
