Herb,If you know a plumber** and can get a short length of 2 or 3 in Dia copper pipe, stick some copper end-caps on it and you're good to go after mounting the hardware. It's not as flimsy as an Altoids container and it's easy to solder to.?
**Home Despot only has pipe in fixed lengths so a plumber is your best bet.?

Kurt,
The cylindrical test chamber is impressive.? I'm sure the test data it yields is more realistic than the one loop procedure used by the OEM's.? Is its construction from a test standard or is it per your own design?
So far I am happy with the numbers I am getting from my fixture.? They have been repeatable for identically marked split ferrites.
I was thinking about building something similar to your cylindrical test chamber using a round altoids mint tin or a Tenny Tea tin.? Still working on a convenient way to disengage the top cover from the inner conductor to change out solid ferrites.
