Putting in a dust collection system

As my odyssey continues, I have reached the point with the shop where I can install the dust collection conduit and hook it up to my new home built 2 hp cyclone.
The cyclone is styled after information obtained from the Bill Pentz website and although not an exact duplicate seems to work quite well.

As you can see from the picture I split the system into two zones.
One zone runs for approximately 22 feet using this six-inch spiral lock tubings for the mains four-inch drops to my tools.
The second zone travels across the width of my shop to the balance of my machines. That run is approximately 30 feet long. I tried to keep the conduits low along the wall in order to maximize the particle velocity entering the system from the tools. I found that the table saw and the bandsaw both required dual four-inch ports thus maximizing the capacity of my six-inch lines.

I used saddle type connections to the spiral lock tubing as I found it impossible to buy sweep elbows locally.

This seemed to work just fine with a small amount of flex tubing between them and the blast gates.
I used an abrasive cut off disc on a small grinder and finished out the trimming by hand with tin snips.
The takeoffs were rivited in place and sealed from the inside with high heat silicone compound. I then taped the outside of the joints with foil tape to reduce the chance of a leak.

The compound miter saw became a bit more of a challenge as it wants to not only push sawdust off the blade from the top but also spreads it quite liberally off the bottom of the blade in a large fan shape.
To help with this I constructed this plastic cage allows the saw to rotate from 50° left to 45° right and also tilt to a 45° miter without interference. To get the shape pretty close I made a mockup template out of cardboard and refined that before I cut the final shape in coroplast.
Coroplast is quite rigid yet easy to bend and fix with wide flange sheet metal screws.
I think I will face the same situation with the Radial Arm saw later although I only kept it for dadoes so I may not build an elaborate trap like this one.

The following picture. shows the position of the blast gate.
I am able to run a 2 inch flex tube up to the opening of the blast gate to direct most of the debris into the line.

this picture shows a vertical gate to which I intend to look up a temporary four-inch line to run such things as a planer and jointer.

This picture shows you the approximate position of the bandsaw along with its double extraction ports the new down draft sanding station that has yet to find a permanent home along the wall.

From new shop

I hope to be able to start sorting out most of my shop materials and tools now and find permanent homes for a lot of those things that are lying in piles around the room so today is a good day for me in that I have 90% of my dust collection hooked up and running.

Cheers
