This may sound funny, but my ""Shop" is 9' by 10'
It has the following in it:
1. A 10" Black & Decker Table Saw ( The new one they came out with last year) Surprisingly good quality for the price.
2. A Sears 34" tabletop radial drill press, mounted on a rolling base, that is capable of horizontal drilling.
3. A Sears tabletop bandsaw (Sorry I bought this, piece of junk!) Thought it would do the "little" stuff. Boy was I wrong. Anything taller that 2-3/4" won't fit.
4. Old Craftsman 16" scroll saw on base.
5. Sears 7-1/2" chop saw I bought when I was cutting molding for our house. (Tore out the old dark Walnut and replaced it with Red Oak)
6. 4' sears joiner on a rolling base.
7. A combo Belt and Disk Sander on a rolling base.
8. Finally I temporarily mount on my 2-1/2' by 5' work bench, My Jet Mini Lathe and Jet 8" Planer.
As you can see, I don't have a lot of room left, but everything is portable!
After looking around, I chose a Jet 1100 DC system and using 4" metal heating duct and fittings, I ran the ductwork around the shop walls, at bench height. Using "Y" fittings, I gave myself at least two access fittings per wall and one location to connect a floor sweeper. Each outlet has it's own blast gate so I can shut off everything but the tool I'm using.
The long and short of it is that by positioning the duct work with "Catch" fittings at the tool, even the dust from sanding is caught by the DC system. Before installing the system, my wife was all over me each time I worked in by shop. (Forgot to mention that the shop is in the basement.)
I haven't had a "Dust" complain since. I can't mount one of the ceiling units to catch the little I miss. Only have 7'6" to the joists.
