It’s autumn now, and already too cool to prime parts outside. I need a place in my shop to do it. I tried a cardboard box on a workbench, but quickly decided that a ventilated booth is required.

With about $8 worth of 1×2 wood strips and $20 of plastic sheeting, a $12 dryer duct, and an existing space heater (w/fan) — I was able to quickly build a 4′ x 5′ x 9.5′ tall spray booth.

I only need to work with relatively small parts. The longest pieces in the empennage are only a few feet long and can be suspended with a vertical orientation. Ventilation is minimal. Hopefully it will be enough.
