My top hat design, other than the rectangular inlet, bellmouth outlet, and air straightener, follow Phil Thien's standard recommendations. I think my drop slot is 1-1/8". The video you linked is definitely showing the slot in the wrong location.
Yes, My slot is 1 1/8" as well, and goes 240 degrees around. On my other Thein separators (one like the original, and a topper), I have the slot ending basically right before my intake, and then starting wherever the 240 degrees took me.
I forgot to ask how wide is your slot that allows to chips to go into the trash can. Did you make the slot 240 degrees? I have been refering to your info and providing links on this forum based on your info on the Thien forum.
I watched these videos on youtube and it appears he has the slot location wrong based on your design and others.

I did just post a question
on the thein forum about the actual location of the slot in a topper. I guess we will find out what they say on there.
One other thing for anyone that is making a Thein separator... Mr Thein was gracious enough to share his design with us. He could have profitted from it by patenting it, but he decided not to. I think it is only fair, that if you use his design, to toss him few bucks as a "thank-you." He has a link on his main page, and he even thanks those that do donate.... (you can see he thanked me on 11/6/11).
I know I have now used it 3 times, and I have suggested others to make one many times. It is by far the most frugal way to have an efficient DC.
I used to be fairly indecisive, but now....... I'm not so sure.
