Putting on the "elf an safety" hat, just be very careful if you have a go at making a spray booth. The fan motor has to be an induction type (i.e. it runs on a.c.) as a brushed motor will create sparks at the commutator. Not a good idea with flammable paint or glue solvents
There was something in Finescale Modeller a few years ago about making a spray booth, and there must be something on the inter web thingy.
I got a telling off from my wife last night for using superglue accelerator on my work bench, sorry the dining table, but I think she would rather put up with the pong than have a large bang from a home made spray booth followed by a smoke blackened husband. Somebody has to catch the spiders
