Received some needed parts at the end of the week. Male and female Luer fittings and some needles.

I wasn't sure just what needle size I would be needing so I picked from the low middle of the offerings and got some 18G. I had to cut the sloped ends off, and found that a belt sander works great for that. It's a little hard to keep the end flat, but if you're careful it can be done.

With the needles and the Luer fittings changing the tip will be a breeze. I was looking for something cheap but ended up just ordering the needles from Ebay. Hell, they're cheap enough it's really not worth trying to come up with something on our own. And I wound up with a box of 100 of them, so I'll have plenty to keep me experimenting for a while.

The fittings I used came in a box of 50 each, so I'm set there too.

I designed and printed a bracket to hold the fitting at the top of the chamber. This one stays there, no matter if you are using the moving table or moving emitter options. Here's what it looks like with the needle in place and ready to run.

The high voltage wire is just alligator clipped onto the needle. Easy and quick to change out. Also allows an attachment point for the lead when you'e running the moving emitter/ plate on the bottom option.

For the moving emitter I made up an extension wire and tubing. Easy and fast to attach and remove. I need this option so I can add spinning cylinders and other accessories later, but I really do prefer the emitter at the top. Shorter wire and less tubing to mess with.

At this point it's a usable machine. Is there more I want to add? Sure is. Mostly ventilation, to get the fumes out of the chamber, and out of the house if we can. I'm lucky in that I cut a hole in the side of my house years back and put in a vent for my 40 watt Full Spectrum laser. Plan is to hook this into that vent.

I also intend to add some environmental control to the chamber, in particular temperature and humidity. Those sensors will have to wait just a bit yet. While not expensive, I'd rather spend the rest of this months check of some chemicals to get started with. Getting this close and not having the stuff here to start experimenting with is driving me nuts! Lol.

All told, this weeks stuff cost me around $40. But keep in mind that's for 100 needles and 50 each of the fittings. So I'm set for those for a while. Heck, I may never get all those fittings used up!
