It is getting too cold to spray outside, so I decided to make a small spray booth. I wanted it to be cheap, able to be stored away, lite and have negative air flow.

Walking around Lowe’s, I came across this 27 gallon storage container for $9 (on sale, usually $12). It looked like the perfect size for my guitar spraying project. I also picked up some 14×24 furnace filters. I also needed a 4” dryer vent duct as well as 20’ of flexible aluminum foil AC duct. The small cyclone fan I picked up at a drug store.

Along with a roll of duct tape, I concocted this spray booth. It works well. The negative air flow pressure generated y the fan seems to be sufficient. When in use, I run the end of the hose out my garage by opening the garage door a few inches (I don’t have a window or exterior door).

I also made a poor man’s version of a freehand holder that saved me about $90 if bought commercially. It consists of a 1 1/4” dowel rod and some supports pocket-holed to a base that is clamped to my assembly table.

I am happy with the results even though it isn’t the prettiest.

I like this idea very much. I do not like to spray in the shop and usually do it just outside the door. Right now you cannot do this in Ky. Where is the fan located in your set up? Is the fan motor right there behind the blade and what inch size is your fan?I spray jewelry boxes and bowls and do have a lazy susan table to turn them. Thanks for the idea and the information. That is a beautiful guitar.

I also spray outside because I have a gas dryer and gas hot water heater in the garage (my shop). Do you think this would work for me? I be skeered. :-)

The fan is located in the cardboard box which is duct taped to the back of the storage bin. It is turned on high, so plugging and unplugging the cord is my on/off.

The fan is about 6” diameter. I would have gone larger, but the fan selections at Lowes and the local drugstore is somewhat limited in January. I originally was going to go with a 20” box fan, but that was too large for the plastic bin. I literally unboxed the fan, set the switch to high, and put it in the box facing out the back and duct taped it shut. I may refine it in the future if I see a need for increased performance.

I checked the performance by lighting a candle, then blowing it out and watching where the smoke went, it certainly was drawn to the bag of the “booth” with negative air pressure.

I hope this helps.

I am not an expert on combustible vapors. So that being said, I wouldn’t spray in the same room with gas appliances.

Can anyone else lend some expertise for MT?

Thanks Jeff. I think I will stick to fair weather spraying outside.

I do like your set up.

Seems like the fan is a standard, non-sealed (arcing) electric motor. If vapor combustion was a serious concern, I think that could really ruin your day. Might want to switch it out for a sealed or squirrel-cage type fan.

Might also be interesting to see if the bin can be converted to a drying oven with the addition of a low heat source.

I think I’m going to side with gianni on this one. I like everything about this build but the fan. Finishing fumes and a motor not made for handling combustibles could lead to an explosion. While I am always a big fan of things that go boom, I like to keep the explosions out of the shop.

The tele guitar is my first steinged instrument. It is a Grizzly kit. I veneered the front and back. I learned a lot making and installingthe bindings. The sides will be dyed brown in the next day or so. More to come when the tele project is completed.

I have a few friends who play. Since I don’t play or have the time and discipline to learn, I wil get ny satisfaction from watching them play it.
