Any tips on construction? Was thinking of using 2x2 and then a thin strip of wood to hold the plastic in place.
Did you notice any places where the plastic was pulling loose from just the staples? Did the filters plug up with paint?
The spinner looks fantastic, overall really like the blue color you used.
Thanks for sharing the photos.
Edit: to actually answer your question, the paintbooth was around $200-250 all said and done.
For the most part the paint booth has held up very well. A few staples have come out, but nothing significant. I have replaced the floor plastic a couple of times just to keep things clean. It only costs about $5 to do it, so cheap insurance.
For construction, just make the frame strong enough to hang mid-weight parts like the rudder, flaps...etc. Anything more than that is overkill. I like having only plastic on the inside. I spray the floor down with water before painting and have washed the walls down on occasion. a wood strip inside seems like a dust source. If you have a lip at the front like I do, run the floor plastic over the lip and out. That way you can blow dust out without it getting caught.
For filters, I am using the cheap home depot woven poly type ($0.98 each). They do a good job cutting out the dust and not hurting the airflow too much. If I were to do it again, I would add a third or maybe forth fan. The filter cuts the flow down by a good 50-60%. I have replaced the filters once for both inlet and outlet, they do get very dusty (mostly the outlet), but you can vacuum them out.
My original plan was to use an old home HVAC blower, I still think that would be best if you can find one cheap. For me nothing popped up at the time. OSHA spray-booth minimum is supposed to be 1mph flow rate so for an 8'x8' cross section: 5280/60=88ft/min. 88x(8x8)=5,632 cuft/min. If I recall, the fans were rated at 3200cuft/min each, but I didn't realize just how great the loss would be with the filter. That is why I suggest more fans.
