On our farm we have an equipment shop, and black smith shop, and a wood shop each with different sets of kits and tools. This thread started as simply documenting the original discussion from the Intervale Farm Hack and was around prioritizing farm shop tools for fabrication of farm tools and prototyping. The original post mentioned that the next step was to prioritize organize and expand. An earlier post also opened up a wiki for modifying organizing and prioritizing http://farmhack.org/wiki/farm-shop-basics. It is fair to say that the focus was on metal, but for fabrication of farm tools, much of the work on our farm does tend to be metal work. The level of equipment needed will really be dictated by the scale and type of operation. You may also notice that on the "to do" list is to separate out advanced fabrication from the basics, and also that urban needs will be different than fabrication or repair. From my perspective there are certain tools that make a lot possible and I know that I wish I had purchased years ago. For example, a metal cutting bandsaw for cutting stock is one of the most used pieces of equipment in my shop - but until I got it I didn't know what I was missing. I haven't put a bridgeport on my own priority list, but it isn't far off and if I had one it would get weekly use redoing bushings, and opening up larger holes for implement pins etc. that the drill press simply isn't set up for. I know that the better our farm shop gets the faster the turn around time and the higher quality the implements that we either create of modify. The faster we can get repairs done or modifications done the more ideas we can try in the field and the better the results on the ground. I agree with the principle of keep it simple, but also I know when there is a build vs. buy calculation that I would rather put the investment in the tools to build than into new paint and waiting for a part to ship from who knows where in the middle of planting or harvest. I would love to see a tread and tool entries for fabrication of tools themselves. Some of the tools I could see documented for farm shops that could be fairly easily fabricated: Gantry crane metal shear shop press forge power hammer heavy shop tables (others)?? there are forums out there for build it yourself machine tools - but the build vs. buy is a little tougher on those (at least for me) but perhaps what might be needed are some categories of tools associated with fabrication of particular types of farm activities for example: heavy farm equipment fabrication light farm implement fabrication hand tool fabrication tools tractor repair - engine/transmission/fuel/frame/body etc. General electrical power transfer (gearboxes, chains, bearings etc.) hydraulic and pneumatic systems irrigation/animal water systems/general farm plumbing including fuel transfer etc. fencing farm building construction (others?) each of these could have their own floating wiki to build out and prioritize?

I find the design challenge of fitting the gasifier components on a tractor daunting, and have thought mostly about sticking with stationary applications - but the install at the driveonwood site looks like it would be fairly functional. The GEK site lists several folks in my area in New England some of whom I have I have connected with. This winter there was some talk about doing a tour of all the functional units. I will attempt to photograph and document what I learn. I am especially interested in the co-generation potential and using it to provide heat and power for our farm buildings. I think a big variable to make it viable in an on-farm installation over the longer haul will be efficient chipping, storage, drying and general materials management to keep it fed with high quality fuel. I think there is a lot in developing on-farm systems and appropriate affordable equipment and associated infrastructure. I have been thinking about a 10KW unit which could also be used to pump water to holding ponds built on the high spots when there is extra capacity. The holding ponds would initially be used for irrigation and animal water, but could be fitted with a microhydro to act like a battery of sorts. My thought is to also use the grid as a backup through a transfer switch when the unit is not running. The forums at All Power Labs is a great resource that I have been using to try and get myself up to speed. http://gekgasifier.com/forums/

That is great news. Please take and post pictures (or any CAD drawings) of the process and any issues you may encounter, and list yourself as a fabricator for this tool if you would like to. I wouldn't be surprised if others would be interested in ordering. For image size, If you click on the images - on the lower right corner you can click to expand the image to fill the screen. You can also click "edit wiki" to access the image source and click to open the image in a new tab or window. You should then be able to download or print from that. If that doesn't work, let me know. I will also post a suggestion to make it easier to download images for printing.

I am really impressed with how clear the NRG images show the different cover. I really like the idea of using slide film as a camera filter - the costs just keep going down! We will be harvesting the plots that were imaged on Monday the 11th. I am in the middle of planting more plots right now and getting the oilseed sunflower planted, but on the other side of that I will be able to dive into this more. Looking forward to it.

I just came across this article that uses range finders (which are fairly cheap) to triangulate and give crop height measurements. I will see if I can get the whole text - here is a link to the [abstract](http://www.sciencedirect.com/science/article/pii/S0168169907002177). I am certainly a supporter of keeping the hardware costs of any of this kind of measurement to a minimum, and then do more processing on the backend (which is more easily shared).
