 I was forgetting to put the chaff screen in, now and then, but noticed, jjust a few seconds into the roast, stopped and started over, and removed it again after cooling started, as you  also figured out.. One time I noticed that I'd forgot to put the screen in, but it was a chaff free decaf bean so I just roasted without it. Wow-High definition viewing! Now I never use the chaff screen at all. Like you I'm roasting in a shed where a little chaff on the floor is no big deal, the vacum cleaner gets it later.  No other  drum roaster  gives you such a clear view, and my profiles don't seem to be effected. I do use less than even 1/4, 1/2 or 1 lb. batches, and depending on the bean and the profile (P1 P2 P3 etc.) I'll add some time before starting and/or some extra time after starting to lengthen the beginning and/or end stage, hitting cool when/if needed, and opening the door during first sometimes, for some beans, and after cooling starts-again when I think it's necessary.
 Tom's advice to remove the right side outer panel to vac out the chaff  every so often is right on. Chaff does get in there and I think it can cause the motor to over heat after a while.
 BTW--sour coffee never an issue so far with the Behmore. Now, wok roasting.....:o(

Thanks for your ideas and input, Les!  Tom cut a hole in the chaff collecto=
r in the Demo Behmo to improve the view and I've been thinking of cutting a=
 similar hole and inserting a piece of heat-resistant glass which would sor=
t of return functionality to the chaff collector by sealing off the hole.
 
Have you found some workable profiles for the small roasts?  I'm still stru=
ggling.
 
Happy Holidays to all!
