When we built my studio, we needed to use the same heating and air
conditioning as the rest of the house. We didn't want to share the
smelly and messy aspects of a working studio with the rest of the
We routed a large vent with an opening fifteen inches square up
through the floor, ending at six feet high. We did not install a
return air vent. I have two vents thru the ceiling, one currently
connected to a hood over my soldering space. The airflow is
excellent. The second vent is for casting and kiln work. The studio
also has windows that open.
I have two vacuum systems. The original one is for the polishing
station and is seldom used since nearly all of my work is finished in
tumblers. The second vacuum is used at my bench when grinding or
sanding with my flex shaft. I use a GRS system at my bench for my
bench pin, engraving ball holder, and other stuff. We used a GRS
bench pin holder with a piece of wood with a 2-inch hole and screen
to attach to a flexible hose that feeds the bench vacuum. It has a
Plexiglas shield to keep stuff from my face. My bench pin is used for
sawing and hand filing. I replace the bench pin with the vacuum
connection when using the flex shaft. In larger studios, the bench
vacuum system is placed permanently and turns on when the flex shaft

addition to an overhead vent.
If I build another studio, the one thing I would change is to put
the vent fans on the roof rather than in the studio. I really hate
Your air quality in your workplace is every bit as important as
lighting and ergonomics for your chair. Do not skimp.
