Failure here. I finished my system on Friday. It's a 2" metal auger in 2" PVC belt driven by a motor from an EFM. Runs briefly than binds up in the tube. I've been holding off filling my bin until I got this working. I'm thinking now I may just fill it and go back to the drawing board for next season. I've got 5 tons to move from point a to point b and I need to get it done.
It is a 1.5 " Auger with a 2" tube If it is binding up you do not have something straight everything must be lined up straight
the pulleys and belts might be off a bit pulling the auger off set making it bind in the tube keep them lined up straight
your type of design will work when set up correctly . you might of set something up wrong pick the phone and give me
or you know who to a call
