Whatever you do, dont' use a shop vac for air extraction. Vacuum cleaners suck filtered air through and around the motor to cool it, and there are armature sparks flying everywhere. The day you decide to just give this lure a spray with some of that lacquer you have lying around, instead of using the water based acrylic, is the day you blow your workshop and probably, house up.
The motor needs to be sealed, so the arching armature will not ignite any solvents or sawdust in the air stream. Some of the best explosions you will ever see, are with sawdust, its as good as gun powder.
Evaporative air conditioner fans are sealed and also oil furnace fans, just suss out the local recyclers.
Somewhere on here there is a few plans and a video on how to make a booth, you will have to do a search, try "paint booth" for a start. I don't have one so can not supply pics. pete
