BUILDING AN INEXPENSIVE SPRAY BOOTH

Golfworks  now  has  a  2'x 2'x 2' metal spray booth available for a
mere $579-- a tad bit pricey.  This spray booth has a exhaust fan on
top and a filter on the inside that allows you to spray all sorts of
finishes onto golf clubheads etc.   without  waiting  for  fumes  to
clear.   The exhaust fan sucks the fumes up and through a duct (that
you supply) to vent  it  outside  your  work  area.  It  also  keeps
overspray from covering your workshop.

I wanted to see if I could make a spray booth on my own and  I  list
the plans here for those interested.

I  first  found  a  nice 12" cylinder type ventilation fan at a farm
supply store.  It runs on 120V, 2.4A and is 1/12 HP  rated  at  1500
CFM  (cubic  feet per minute).  The one Golfworks sells has a 1/3 HP
motor.  If I did it again, I'd probably buy a bit larger unit  (more
CFM).

Anyway, I constructed the spray booth out of inexpensive wafer(chip)
board using 3/4" inch thick, 2' x 4' sections readily  available  at
lumber  yards.   I  simply made a box using two 2' by 2' squares for
the top and bottom and three 2' x 4' rectangles for  the  sides  and
back.   I  put  the box together using wood screws and wood glue for
strength.


Then,  I cut a hole in the top for the fan and mounted it to the top
of the booth with sheet metal screws.  I used  a  10"  to  8"  sheet
metal flashing and attached it to the top of the fan to adapt to the
8" flexible aluminum ductwork.  The ductwork is simply attached with
to the flashing with duct tape.


I put a simple plastic junction box on top of the spray  booth  with
separate  switches for the fan and a light.  I added the light as an
additional feature over what Golfworks had as I want to SEE  what  I
am  painting.   I  mounted  the  light in the upper FRONT right hand
corner of the booth facing toward the BACK of the booth.  I  put  it
at a slight downward angle to illuminate the entire booth.  A simple
100 watt bulb screwed into a surface  mount  fixture  will  suffice.
All  the  wiring to the fan, lights, and switches was done using the
end of a 25' heavy duty extension cord  with  the  female  connector
taken off.


The  filter  is simply mounted inside the box directly under the fan
with the use of wood strips so that it  can  be  slide  in  and  out
easily.

The spray booth is BIG and will set nicely on the floor  or  can  be
mounted  on  a  small  1-2'  tall box if you like. It works well for
clearing the fumes quickly, but I'd still recommend you use a  paint
respirator while using it.
