Posted Fri Dec 27, 2013, 4:57am Subject: Anyone every make a new drum for the Behmor?
I'm lovin' my Behmor, big time, and tend buck the prevalent trend, preferring to roast 1/4lb batches (more fun experimenting, more frequent roasting smell, etc). But I've noticed that I do indeed get more consistent and maybe deeper roasts with 1/2lb batches, so I've been thinking about the drum size in relation to smaller roasts, including the effect of the sheer mass of beans in the basket with larger roasts, as opposed to the 1/4lb of beans floating around in the big drum.. I have an idea that may be completely crazy, but maybe you can help.
I did a search and didn't see anything about this, which does make me think this is a knucklehead idea. But, leaving aside that I'd be voiding my warranty, do you think a smaller drum for 1/4lb roasts would help with consistency by mimicking the bean mass of larger roasts? Has anyone ever tried this? The drum's diameter couldn't be any less so that the same proximity to the heating elements is maintained, but if the drum were narrower, it would "collect" the beans into a mass size more like you have with 1/2lb roasts.
If this is a good idea - and I put a big *if* on that, pending your collective wisdom - how might I go about it? In my fevered brain, I imagine a single bar going across, around which I'd squirrel together a mesh drum with internal fins. I have appropriate-sized mesh, but I see the bar as a challenge, in particular getting a metal bar cut to a specific length, and having the square end on the right.
I'd love to know your thoughts, and thanks in advance for them, whether about this idea of bean mass being part of the issue of consistency with 1/4lb roasts in the Behmor, whether my idea has potential or is completely insane, or how I might go about doing it if it seems a good idea.

If I drank any more coffee, I'd float away!
I have an experiment going that may provide some data. After reading a few posts here on using rotisserie ovens as coffee roasters, I found a rotisserie on Craigslist and am going to give it a shot. It came with a vegetable roasting drum so I don't need to make a drum for it. Sure enough, it's about 2/3 the size of the regular Behmor drum. Of course, using a Foreman rotisserie doesn't begin to compare with a Behmor roast, so any "data" I collect about bean mass will be dubious at best!
