I think you're on to something with the washer being partially suspended by the drive belt. It could have the same result on friction as bottom mounted drive wheel. It would need to be a really strong belt and pulely/drive shaft, the weights can be considerable. It would keep the motor located above to help keep it dry as well. What would receive the belt on the barrel? The bolts as chainring teeth need upgrade for sure.

I also like the idea of using locally harvested wood for the barrel. Locust grows fast and is incredibly rot resistant. A bunch of saplings could be used without any milling, just attach to the rings. The rings would remain a big expense, though.

Here is a link to a discussion that started at the Intervale/Essex event this weekend. http://farmhack.net/forums/root-washer-improvement Maybe we should merge these posts or create a tool page.

Thanks for helping me understand this. It sounds like a fun project.

Interesting read. So time of flight is based on trilateration and not triangulation. If a method of triangulation could be figured out, would this overcome the processor speed issues?

I don't know much about how location is figured within a wireless network, I'm going to check out your link. I'm coming from a sailing background where we take a compass bearing from 2, or better 3, objects like water towers or light houses. By plotting these angles onto a chart from their known position, (it's marked on the chart) you can fix your position by finding where these lines meet. I guess that's where I'm coming from in thinking that triangulation has to do with compass direction and not distance.

There was some talk about the difficulty determining distance within this network. If there is triangulation from three known points it is direction and not distance that's needed to calculate position. How could this be achieved?
