I shall do the maple test and let you know how it works. Won't be today as it a nice day to be outside and get the yard ready for winter.

Retired2,
All pipes are 6". The diameter of the separator is 22". I ran my thickness planner and all of the chips are in the drum. If there is any bypass I cannot see it. I ran the collector after dark and passed a light through the exhaust and along the exhaust line and did not see any dust.
I live in Ohio and will see how the shop temperature is affected by the DC. Like you say I might need a dual setup but for now all is great! I picked up a couple of leafs and you can see them going in circles. Will keep an eye on things once the drum starts filling up.

I finished the DC and all is working well. I made a few adjustments along the way. I tried the rectangle opening and had trouble with getting the input port lined up with the wall so I went with a 6" round input port. I used 3/4" plywood for the floor and then used a 45 degree router bit to reduce the edge of the opening to 1/8". I am using a motor and impeller from a  Model 200S Cincinnati Fan dust collector. It is a 2 HP 1100 CFM with a  12 1/4" impeller. I only run the DC when operating the power tools so I chose to exhaust the output outside rather than through a filter. My work shop/garage is not heated so I don't think it will be a problem once the snow falls. I was helped immeasurable by all of the information posted here. Thanks to everyone.
One question. Is it normal for the dust collecting in the barrel to spin?

Top hat with 1/4" hardboard for the floor, sheet metal for the wall and 3/4" plywood for the ceiling. I am using a rectangle for the input opening. I will attach photos when it's finished. Thanks for the help.

Thank you. I will position the slot so it starts at the left side of the inlet as shown in you photo.

After two months of planning I have my DC almost finished. I need to cut the 1 1/8" slot and cannot find information on location. I have 120 degrees for the opening, I can place it in line vertical with the side wall but do not know where to start or end it. Any help would be appreciated.
