[Homeroast] On Topic: Popper-Roasting

Hi, Alchemist,
Thanks for your thoughts!  Glad to know nichrome doesn't 'tire out' (indeed that was one of my worries).
I will try reducing air flow.  The Wear-Ever 1400W Popcorn Pumper is tilted to improve bean motion.
It seems to me that I read that Increasing Bean Load shortened popper roast time (counterintuitively), but I might be mis-remembering.
I will check the line voltage, too.
This list has been a wonderful resource for me!
Happy Roasting,
robert yoder
