Paint booth part II

[rjspitz]

Some of you might remember my homemade bomb, ahem, I mean paint booth. After a couple of days and several trips to the hardware store, here's what I came up with.

I made a fan with an out-board motor. Kind of follows the design of an axial fan in that the motor spins the blades via a belt (thanks to byrdman's idea). The fan housing was made of wood, while the blades were the plastic ones from the box fan (no sparks if they hit). The shaft was steel and turned in aluminum pillow blocks with copper liners (again, no sparks). I was able to fit a filter on either side of the fan blades for optimum cleaning affect.

It all worked very well I thought. And the high speed of the fan actually worked better to exhaust the booth than when I used two box fans.

Thanks to all for you inputs and keeping me safe.

Here are a few pics of the fan after use and of what I was painting (race bike bodywork).

cheers,

Looks good! Be sure to post some pics of the bike assembled in race trim.

NICE! I need to build one now. Thanks for posting your results.

Wow, nice work!

Nice job on the reworked fan!

WELL EXECUTED sir!

It looks as though you are pulling air out of the booth, right? Are you filtering the input hole?

Thanks guys.

Yes, it is a negative pressure setup, but I'm not filtering the incoming air. I'm not too worried about the finish on the bike. I fully expect to drop the bike anyways. If I never lay it on the ground, then I'm not riding the piss out of it

That is WELL thought out! Looks great!

I have a window directly in front of my paint booth. I put a furnace filter in the window and pull the incoming air through it, into the booth. Squirrel cage is in the roof of the booth.

Nice re-work on the fan... much better.

Good job!

I've seen pillow blocks at the parts store and I know what they do but I could never really come up with an application. I just haven't come across a need for something like that - until now. Thanks!

Excellent work. I think a lot of us would love to get more detail on how you built the fan-- parts, pricing, even some step by steps-- because you're not the only one who's hesitating on building a paint booth due to sparking issues.
