Airbrush Spray Booth

For someone who doesn’t have a range of woodworking tools, a bandsaw, tablesaw, spindle sander and so on this would make a great CNC project! Happily for me, I have all those things and quite enjoy using them, so when my old duct tape and cardboard box booth (which had served me perfectly well for decades) found it’s way into the recycle bin, I gathered up a few leftover bits PVC board and made something that would double as a place to store the painting gear.




If anyone’s interested in using it as the basis for a CNC project the Onshape document is here to do with as you wish.

There are lots of router templates incorporated that you won’t need, and I’ll add an instruction for the removable door hooks on Printables later this week.

SO jealous of your style!!

Nice!!!

Thanks, but don’t be, if you see something you like, please steal it or modify it for your own project that makes me less embarrassed about showing off!

Generally when I build a tool, I try to make it something I’m happy to use for the long term. This replaces a temporary, battered old carton which has more or less lasted a lifetime, but just looked as though I didn’t care.

There are some nice touches (I think the lights work well - I’ll post a pic later today) and the lift off “hinges” work really nicely and could be used in other places.

The grille is just an affectation - a standard furnace filter would do the job - so I guess you could say that was me pleasuring myself! :grin:

It’s good you still find joy in it, a lot of older people seem to not care about pleasuring themselves. :face_blowing_a_kiss:

That’s actually really sick. I’m not sure if you came up with them but that venting method out the sides and those clasps/hangers in front are damn clever.

what are you using to pull air through the filter? I used to do the whole ‘box fan/AC filter’ type of paint booth, but found the air flow, even on the lowest setting, to be too high.

I would think just a 120mm computer fan would probably provide enough air flow to pull fumes through the filter, but not so much as to create a large wind current.

I was just thinking about something like this last week while using a cardboard box with no light to spray paint. I will be stealing some of your ideas here. I think I’ll hinge the front cover and put something to hold it level. My current air brush setup is a bit more temporarily held in place (as seen in the picture).

In related news, my son and I both got plastic models for Christmas and have been building together this past week. I’m way out of practice. My airbrush work is taking me multiple re-paints to get a decent finish. I really messed up last night when I forgot you can’t wet-sand acrylic paint as the water softens the paint. I really made a mess of what you see in the last photo and pretty much need to do yet another repaint :frowning:

The vent is one of my 90mm magnetic connectors - duct details described below.

I really must update this collection - there are quite a few connectors I haven’t uploaded yet.

The clasp/hangers are also my design - I will upload them this week sometime. If you are thinking of designing something similar, just note the small detail that makes them work nicely - the “gate” on the lower clasp is smaller than on the top - that makes it easy to engage the bottom pins then locate the top.

I have a 4" inline fan which is used for laser exhaust - I have used an 8" bathroom exhaust fan for years. If the airflow is too great (which is unlikely as I have 25mm of filter fabric) I can just use a restrictor plate (fancy name for a bit of cardboard with a hole in it) between the magnetic fittings.

There’s no shortage of exhaust ducts at my place - I usually just connect to my tablesaw blade guard dropper and exhaust into the ducting system - but it’s no biggie to plug it into the 8" direct to outside outlets as well (in both cases with the other fans turned off!)

I’ve seen that! If you notice my shiny new compressor - that’s because it was cheaper to buy that than to separately buy a new hose, regulator and water trap! :open_mouth:

Ahh yes, my son-in-law gave me one as a joke as well - which prompted this whole “time to sort the airbrush stuff” thing.

Who’s laughing now? :rofl: (I haven’t used the airbrush in years either and even then it’s mostly been for touch up work, so we’ll see how plastic models go.

That should be fine for acrylic paints. I wouldn’t spray lacquer though. Supposedly the paint fumes from lacquer paint are flammable. I had to search and find an ‘explosion’ proof fan for my large ‘full size’ paint booth. I don’t know how much of a big deal it really is, but I always err on the side of caution with stuff like that. I’m also spraying HVLP in the big paint booth, so there’s more of a cloud being sucked out by the exhaust fan. Might be less of a deal in a smaller booth.

I’ve only been spraying acrylic with the smaller paint brush, so less concerned.

Very flammable. It’s not a big deal until the explosion happens. I like to stay away from that kind of stuff - it also tends to filter into the house and leave me in a different kind of trouble.

I haven’t sprayed lacquer for years but used to do that in a fully enclosed garage with a good mask and no exhaust - used to level the final coat on furniture and wood stuff with a very light mist of thinners, what could possibly go wrong?
