Anybody familiar with ECM, or Electro-Chemical Machining?

I've started gathering the required "STUFF" to put together the test rig. I've got my original Sunhokey 3D printer that has been unused since I got my D6 clone and the MP10, that will be the basis of the rig. I got a cheap, $10, 12VDC peristaltic aquarium dosing pump to power the "jet". And I got some blunt 14G hypodermic needles to be the actual jet nozzle. I think the pack of 10 needles and 3cc syringes was also about $10.
If this project doesn't work out, I'll still got a lifetime supply of micro oilers/glue injectors. Don't know what I'd do with the pump though, maybe a working water cannon for the RC Benchy?

More stuff was delivered today, but it's one step forward and two steps back. I got the silicon tubing for the electrolyte return to tank line.
Ebay claims the silicon supply tubing was delivered too. Maybe it was delivered, but not to my house. We'll wait a couple of days and see what happens, maybe it'll show up.
The power supply that I ordered was delivered, but somewhere in its' travels it took a serious hit. The case is mangled on the terminal strip end to the point that you can't even open the finger-safe terminal protector. I've started a return on that one. I mean it's a solid state power supply, so it should be OK, and I can straighten the aluminum case, but still...

Don, I've got my fair share of inadequate packaging from that big river company. On the other hand sometimes I get a giant box with something a tenth the size in it and lots of brown paper. Bummer about the power supply. What size and type is it?
ddmckee54:
It's a Chinese clone made by a company that apparently has no name. I contacted the seller and he told me to do what was needed to see if it's even functional, then we'd discuss either a partial refund or a replacement. When this thing hit, it hit hard enough that not only was one corner of the case folded over, the entire bottom of the case was racked out of square.
It's supposed to be a 36V/15A power supply, and when wired up it does crank out a nominal 36 volts with no load. I couldn't think of anything that I could use as a load. At least I couldn't think of anything that wouldn't potentially get me nominated for a Darwin Award.
vtsteam:
If you're in the U.S. and 120V is your standard, do you have any incandescent light bulbs left? If you do, It won't light them much, but will present a load. Nowhere near 15 amps, but something.
An old corded 120V electric drill with brushes will also run on DC, again not at full power with only 36 volts, but it will run.
