I was searching for an 8" to 10" tall by 6" to 8" diameter Pyrex tube last night on the net, and nothing came up. It is all very small in diameter. I think that would be the best bet though, if the proper size can be found, because it is tempered. In the meantime, I got a glass vase and a glass cutter . . . could be interesting. I am going to put stove grade mesh on the bottom, securing it with an air duct clamp. I am going to try to find a small hinge at the hardware store to make a hinged mesh top for the tube glass roasting chamber.
The stovepipe is a great / easy idea, but I really want to see the beans blowing around
. Sonofresco chamber is also a great idea, but I am willing to bet they want quite a bit of money for that bad boy. The vase, glass cutter, clamps, and mesh rang it right around $25. Now it might not work, but being creative is half of the fun!
I am torn between studying for a Physiology test I have on Monday and making this roaster!
Cheers,
Mike
