I just harvested from my flow through bin today and noticed that the castings are hanging about 3-4" above the PVC pipe. Question: how do I get the castings to settle back down to the pipe without causing major avalanche? I had noticed during the last harvest that about 1/2 of the bin was above the pipe, now it is all above the pipe. Any suggestions from veteran flow through bin owners would be appreciated.

"Arching" or "bridging" is fairly common on narrow flow throughs. I just bought an 18" icing spatula to run along the sides as described by Daniel - I'll let you know how it works next time. In the past, I would just break the bridge by inserting a small dull blade or trowel in the middle of the bridge area, and when you pull it a bit and take it out, a small cave-in results. Better than an avalanche and minimizes casualties.
