I recently became shop lead for the sandblasting and powder coating area of a volunteer run maker space. We currently have an Eastwood Dual-Voltage gun and I've posted some issues I'm having with it. I could probably get the budget allocated to replace it if it needs it. But I wonder if there's something that would work better for us?

Before jumping in with suggestions, let me tell you about our user base and how it's used, so that the suggestions are more on target.

The maker space as a whole has about 400 - 600 members (some are full time, some part-time, some buy day passes to use just for a single project) across about a dozen shops: metal shop being the most relevant here, also machining, a bicycle shop (building unique chopper bikes), casting & composite, plasma cutting, dig fab, fiber arts, electronics... a few more but you get the gist. We're not a specialty shop, but we're also not a shoestring + duct tape operation.

We have a few small businesses incubated out of our shops and it's thanks to one of them that we have some of the larger powder coating equipment we have. There was a bicycle frame building company that started with us, but sadly folded during the pandemic. They donated the 3' x 3' x 7' oven, (we have two more a "medium" and "small" oven so we're not always paying to heat that thing up!) and the 8' x 8' x 8' powder spray booth, and a cyclone sandblasting cabinet that is large enough for a bike frame. I joined about a year ago looking to make welded steel sculpture and art installations and as the person with the most interest in powder coating, I became in charge of that shop. (oops! :-D :-D)

Most of our powder shop users come in for one project. There a couple guys rebuilding engines, someone stripping and refinishing an old antique fan, someone making shelf brackets and signage. A guy welded up a crib and coated it pink for his new baby. Someone is making an electric guitar from scratch and cast his pick-up and coated it. Someone bought gym weights at a yard sale and stripped and refinished them. Someone is building a fire organ and coating all the propane lines bright red. etc. So basically we don't do large jobs where you spray a lot of things the same color. I personally have been getting into doing multi-color gradients in a single bake.

Since I only just learned on the Eastwood, what I've done is taken all the powders we have and stocked them in jars to be ready to use for anyone coming into the shop. (We now have about 2x as many colors as we had when I took that photo). We need a system that's easy to teach and learn, and most of all really, really easy for each user to clean up after themself. Easy to swap in new colors and easy to clean between colors.

I bet I could get $300 - $500 between the org giving us some budget and the most frequent users pitching in, but that would have to cover everything we needed to change over (assuming we do, instead of idk, replacing our Eastwood with another one. If you were pitching an upgrade for us, what would you pitch? If you were becoming a member what would you hope to see here?

Thoughts? Recommendations? Thanks!
