I would recommend taking the design documents to a local fabrication shop to get a quote. For barley you will want the hammer design modification for sure (rather than the impact huller design which is fine for oats etc.). The second stage of winnowing the hulls and cleaning the seed is also important to consider. A clipper seed cleaner properly set up can get you most of the way there. I expect it could all be built for less than $2000. If a fabricator gets setup to do a small production run of kits, the cost could be substantially less. If you do build a version, please post your results and costs!
I think Louis makes a good point. I have been thinking about the same thing with the roller crimper tool and the iFARM tool. The original tool wiki posted has been lost with new approaches that confuses the post more than clarifies the progression and relationships. I think it would be great to have the concept of branching so that each of the new tools could be edited and modified on their own merit, but the evolution and heritage flows through. It is also an important part of providing credit for previous work too.
I also think that as some of these tools are used together that the concept of a meta-tools or "kits" becomes important. Some tools are a new organization of other sub-tools or components. For example, a "small scale grain production kit" is a tool that I will be developing. It is a tool that will assemble a number of other tools together in a particular combination of hardware, decision support software and spreadsheets to solve a particular economic and technical problem. Each individual tool will also have a tool wiki, or even additional sub wikis but they also have a relationship together in how the operate. Open shops enables some custom grouping of tools, but I think the ability to segment and custom organize groups of tools to address particular problems would make the content more meaningful.
This type of tagging with defined functional relationships would also enable us to group many of the tools that are attempting to solve similar problems, like data logging and automation, prone position weeding/harvesting, roller crimping, climate control etc...
I wonder if some visual navigation of tool relationships might be in the future...
