My original plan was to have the separator right under the inlet, unfortunately grizzly thought it would be a  good idea to make the connector not quite square so without some sort of welded up connector there is no way for the inlet to point straight down, or up. I will clean the connection up so that it shorter and straighter.

I did some pretty heavy clean up the other day including sucking out everything in the bottom of my cabinet saw. The bag has a light dusting of fine stuff on it but no significant chips made it through. I think this thing is just about done. The only other test is going to be when I have it hooked up to jointer or planer. If it can digest that stuff I am calling this done.

Alright I have things nearly set up now. I have done some testing and the Thien top hat is performing. I have the outlet set at 3 inches from the baffle. I have it set to be adjustable so I may play with it a bit.







The bag had no significant increase from what was in it. I did see some very fine just coming from an uncapped hole in the collector, so I am not sure how it is doing with the fine stuff.

The inlet is in. It still needs to be cleaned up and sealed.

I picked up a Grizzly G0548 from the outlet center the other day. I was strongly considering going with the HF collector, but I got the grizzly for $325. Anyways this will allow me to go with 6" ducting. I am building my top hat out of junk I have laying around. The diameter is 2 inches and the height is 12 inches. The slot is an inch and an 8th and the top and bottom are both 1/2". The sides are 2 layers of glued up aluminum flashing. I am not sure if this is to tall or not. The inlet is a 6" metal hvac duct that I have made a rectangle to get more of the air flow in contact with the sides of the separator. Here are a few pics:

I think credit is given so I don't know why it would be an issue. Also, you are not hosting the images so if there was any blow back it would have to go to the hosting site.

Sorry for bumping a 2 year old thread but I thought this might be info that future lurkers might find useful. Wood magazine did a test in issue 182. They tested basically the same collectors we are using today, the main difference is that most of these have 1-30 micron bags or they come with filters. I believe the test, tested clean equipment. Either way the collectors that have canister filters on them should maintain the suction that they achieved in this test. Hopefully this will clear the air a bit on what size duct you should be using.
