Ok finally got a little time to continue. First lets talk about blast gates and routing boxes. I made these from plans in either Wood magazine or Shop Notes but did not write the issue on it.
This gate is for individual tools or can be mounted in the duct . Basically this one is ply for sides and 1/8 masonite scrap for the blade. The plastic PVC connector is a piece of thinwall with about 1/2 inch cut out and then use PVC glue. This will allow the 4 inch flex to be attached.This could be bypassed with plastic ports but that would cost more than buying a complete plastic blast gate. For the inline mount the blade goes completely thru with a bit of ply on either side to block the slot when the gate is open or closed.
This is a plastic gate I found recently with a threaded ends to attach flex.
This schematic shows you a better way to build with laminate to make opening easier allow for a tighter fit.
This is a distribution box made on the same principle as the gates with the gates either mounted to the box or as part of the box (ends).
Below is the same box on top of the cyclone with many more ports.
THIS is the box I made for the lathe. Hose was experimented with and works best from the back straight in.
This tool presents dust control problems. The hood at the back has been enlarged since this photo. What you cannot see is there is a box under the saw, since most CMS have opening at the bottom. The space at the bottom of the saw is sealed with pipe insulation. There is also a hose for the saws own collection out of sight feeding into the box. All this is feed to the PVC on the right.
Now there is a upgrade you can make to your dust collector. Jet came out with a Vortex system to enhance the amount of flow of dust into the bottom bag instead of into the upper bag or canister filter. This keeps the upper cleaner longer and allows greater collection due to less blockage build up.The article below will show you how to do it and on that page are a few more tips.
If you have questions I am always around.
