Well, I did get the Jet 1100 Vortex and I like it. Much quieter than the old shop vac and doesn't use any more footprint than the SV and the Dust Deputy together. Collection bag holds plenty and is easy to take off and dump.
But.
I am a one-man, one tool at a time, shop and I just run the hose from the DC to whichever tool I'm using at the time. This sometimes requires that I neck down to a 1-1/2" hose. (track saw, router, sander) The problem with this is that this restricts the flow through the 4" hose so much that my CFM drops below what is necessary to get the sawdust to the DC. It collects in the 4" tubing. After running a job, I disconnect each segment of my hose-run starting with the tool connection, working my way back to the 4" hose. This allows the CFM to increase and sucks the sawdust on into the DC.
For now, I only have one tool, my band saw, that has a 4" port and it really does just fine on a 2" hose.
So, my 4" hose sections have gone into storage for now and I am using 2" primarily. Using the 2" straight from the DC's 4" port and then necking down to the small hose for the small-hose tools seems to work just fine.
Putting in a "system" is not in the picture at this time. It seems strange to have the Jet 1100 just using 2" hose but it seems to work just fine for me.
I ponied up for the remote control start switch as well. I keep the remote unit clipped to my apron. Very convenient.
Had a minor crisis the other day. Hit some metal in some (new) plywood I was routing and started some dust smoldering. I didn't get any of the glowing/smoldering debris into the DC but being the ex-firefighter worry-wart that I am, I emptied the DC into a metal trash can and set it out by the street for the night. Only about a 5-gal. bucket load of dust. Nothing exciting happened, no fires, etc. But can't be too careful. I am thinking about a smoke alarm for the shop (my garage) that I can activate when I go in for the night. One that I will be able to hear from inside the house. Either that or move the DC to an outside location and set up a fire sprinkler system. Did I mention that I am a worry-wart?
