I also just secured a spot in the basement of my new home for my scale model
workshop. I am in the building while still planning stage. I framed it out
yesterday, approx 10' x 14'
I am undecided as to what exhaust fan to buy as well as lighting. When I was in
school I took a year of auto body and spent most of it in the spray booth.
Lighting was in the ceiling and both side walls to eliminate shadows. The
actual lighting fixture was attached to the outside of the booth, with a piece
of clear plexiglass/lexan sealed to the wall. This was to prevent explosions,
which is much more likely when painting auto's with large guns and huge clouds
of atomized paint.
In my scale model workshop I am going to do my painting in one of the corners.
I was thinking of putting in a fixture in each wall of the corner and one in
the ceiling over that immediate area, for the same reason, to eliminate shadows
plus I have bad eyesight. The fixtures are cheap enough. I may spend a little
extra and get bulbs that mimic natural sunlight or I may just use regular cool
white bulbs, we'll see how the budget goes. I am going to paint the shop walls
and ceiling white to further help keep everything bright. I'll probably put the
spraying area lights on a seperate switch so the room isn't lit like the sun
when I'm just assembling stuff or doing anything that doesn't require too much
The fan is kind of expensive, even though I havent picked one out, they all
seem to be expensive. On the wall behind where I paint I was going to cut out a
portion of the wall and install maybe 2 furnace filters (16 x 20 ?) which can
be removed/replaced as needed. This will give me clean air into the shop area,
I'm hoping. I also think it's necessary for the exhaust fan to work
correctly/efficiently. In the auto spray booth at school, the two doors where
you drove the car in were loaded with filters, but that was because of the
enormous roof mounted exhaust fans. I think 2 should be fine for my needs.
So "my" sticking point is the exhaust fan. How many cfm's does it need to be. I
was going to use a home depot bathroom fan ($129 for 300 cfm's) but they are
priced high because they are designed to be quiet and they aren't all that
powerful. They just have to remove a little stink from a little room, sometimes
a big stink. Noise isn't much of a concern seeing that the 5 hp compressor
almost rattles the whole house . That, by the way, will be at the other end of
the basement, about 50 feet away. I'm not sure where to even look to get a
commercial duty fan. I'm sure google will point me in the right direction.
I was also thinking of using a blower, mounted to the furnace filters, to push
air in and work with the exhaust fan. I dont know if it would be needed though,
so that will be an add on if the exhaust fan doesnt cut it by itself. I dont
want so much air blowing by that it sucks the paint away before it lands on the
model, but I do want it to get rid of all the overspray as I will undoubtedly
have many different things being painted in various stages & colors and I don't
want overspray ruining them.
I'm prob going to insulate the walls as it is cold in New England in winter and
my cellar ranges from 50 - 65 depending on the temp outside. So if I use a
small heater, (home depot has a few decent ones that are inexpensive and have
digital temp setting) the heater shouldn't have to come on too much to keep the
It will be so nice to have a dust free environment to work on my models. when I
leave and come back the next day, everything should be the same as I left it.
Currently I am spraying in my woodshop section of the cellar. It's been OK, but
I spend a lot of time cleaning the place and the models between/before coats.
Anyways, if you have any good ideas about exhausting the air, good place to get
the fan, good fan to get etc, let me know. As well as ideas on shelving,
storage, etc etc. I'd like to hear them
Good Luck, take care, Ron, 38, Boston area
