    Jim, I have looked at the Harvey DC as well so I would be interested in your opinion after you have used it for awhile. I am sure you will post pics when you get it all done. It is a big project with a lot of decisions to be made and I think you have done very well.

      The G700 is excellent and I only have two small complaints...the grid in the inlet tends to catch "fluffy" shavings from thicknessing material and the master power switch is on the back of the machine. The latter isn't an issue when using it mobile, but when placing it to a wall and under a surface like I will be doing once I move on to duct work requires I provide an alternative master power solution which I will be doing. OTOH, the unit's sound level is remarkable, even when fully cranked and the air flow is consistently good. And catching a sale, you can buy two of these things for the cost of one 5 hp cyclone.

        May I suggest automatic blast gates to each machine which will auto turn on your DC and eliminates the master switch issue. I installed mine a few years ago and it is one of the best improvement in my shop. I bought the plastic ones to save a bit of coin and just jumpered around for static mitigation and they have a connector just for that on them. I have never had one fail or jam. The customer support from Ivac is outstanding. FWIW

          I've never felt the need for auto blast gates and I also leave the DC running as I move between machines. It's not something I can justify the expense for and with my machine grouping, gates I'd be using the most are within a step or three of each other. There is also the extra expense of putting together current sensing because all my large machines are 240v 30 amp which cannot plug directly into typical auto-gate devices. The singular piece of plastic "duct" in my shop is that last foot on the CNC. All my duct work is quick connect metal including the gates.

          Auto DC start cannot be used with the Harvey G700. Why? It's controlled by a VFD (variable speed) so "on/off" relative to collection or not is handled by the remote or the front panel of the machine. Ramp up and ramp down are also much longer than a traditional DC as that puts less strain on the motor for spinning the blower up and down with a gradual ramping in both directions. The accommodation I need to make is for the "mains" on/off switch which is physically in the back of the device and will not be accessible once my duct is installed and connected to the G700. The solution is an inline box that has a duplicate rotary mains switch that will be mounted on the front of the platform over the DC. The switch on the Harvey machine will be left in the "on" position full time and actual on/off disconnection will be on the outboard rotary switch.

            Jim, Ivac auto gates have their own individual current sensing connectors which attach to the power cord of the machine it closes the gate and turns on the DC. You should look at their website. My machines are also 220V and the IVAC remote for the DC is AC not DC. The blast gate senses amps from the machine power cord and sends a signal to the DC remote to turn on and close the blast gate as the same time. I would not want my DC to run all the time regardless of variable speed. There is always more than one way to skin a cat. Ivac is pricy and for my ten machines it was about $1k for the equipment. There is no wrong way as long as you keep the dust out of your lungs. Which is a good segue into getting a Dylos air quality meter if you don't already have one or something similar. I have many woodworking friends who tell me the can see the dust and then turn on the DCs which is too bad for them. The dust that will eventually kill you is the dust you cannot see. I don't care how good your DC at the machines are they cannot stop it all. A quality air meter will definitely prove that to you. IMHO. Happy New Year and many following my friend.

              I do have a dust sensor in the shop. And an air cleaner. I started my woodworking journey in about 1997 and have always strived to do things well. It's good to know that iVac has a current sensing solution. I'm still not going that way, but for folks that want auto gates, that's a great solution. But again, you can't use the DC on/off feature with the Harvey because it's VFD controlled...or at least not without a very creative hack into the remote control system. My comment about running the DC for longer periods of time is because it's literally machine killing to be turning it on and off more than a few times an hour. Oneida, for example, even tells customer that in specifications.
