OK, well, that establishes the stuff as "sufficient and to-purpose", if
you're using the results for injection molding!

Scott, you obviously came on the scene a bit late, cuz before the flurry
of most valuable (I might add) stuff concerning EMC, one of the VERY key
bits of interest was EDM systems we could implement as hobbyists.

Since there IS most definitely a very REAL interest in any practical EDM
implementations possible for us guys, here's what I'd suggest to get
over your "but, maybe it would be boring" worries. You COULD just be
ready to field a bunch of questions, but what might speed things up AND
make it easier/funner for you, is to outline the basics of your
design/setup. Break it up into a series of posts; trust me, you WON'T
bore anyone. :) Right guys? Label it the "Acorn EDM series, Part 1, 2
...)

Start with the basic layout of your system, with power supply and
electrode scheme, and then maybe outline what you've found are the
practical limits of motion rates, and how you've solved them.

As you see the interest build, that might motivate you to scribble up
some simple drawings in any sketching program, IF/wherever you might
need to, and you can then post them in the shared files area of this
group. If you need to do that, and don't know how, just ASK. Trust me,
probly a dozen guys will step up to help you.

Bottom line is, YES there is considerable interest in practical EDM
systems. Put "boredome" outta yer mind. Forget the stage-fright of the
spotlight, it isn't gonna be a problem, either. Just think about how you
can OUTLINE what you've done to the rest of us eagerly interested, to
get started in the collaboration, and then questions and observations
will flow outta that, and you'll be offNrunning on sharing your
contribs. Try it; you'll like it! :)

I'd love to be able to configure a small EDM setup; in fact I'm
collecting everything I can to understand the "home shop" practicalities
more. I'd bet dollars2donuts I'm not alone. :)
