Since then, we have been brainstorming ways to fix this problem and have recently made a new plate to insert in the front piece of the sheller. The only difficulty is being able to test on a large enough sample to make any conclusive results. Since it isn't harvest season yet in Arusha, it's necessary to continue going out to other villages who have their harvest a bit earlier (why we went to Babati).
Other than jamming, the biggest issue is complaints of thread ware, since if it occurs, the machine is completely unusable. It is very hard to pinpoint the problem because it could take maybe 30 sacks of maize or 1000 for any thread ware to occur! Jamming could be causing the thread ware or it may be machining in China. Since we're not here for much longer, Colin and I are trying to summarize all the things that need to be looked at and figure out the best ways to do solid testing when more corn is available.
