@Bill The fix was on Sunday to give you a reference of when emails were probably ending up in people's spam folders. Let me know if you are suspicious of this happening again.
Sorry I am not a diligent blogger. I haven't had a chance to check back in. I can share the docs and doc templates I am using. Really took the idea of simply turning a normal system into a digital system leaving room to customize to fit the farm needs. This has led to a few different templates. I would love to see your system as well. email me nicwelty@gmail.com (this is also the account I access google docs through)
thanks

Hi Chandler, I don't think it is eaxctly a question of which tractors had "ground drive PTO's" they were all made to have engine driven PTO's, but it is a question of where in the drive line the PTO originated. If it came from the engine directly then shifting gears might not work. Some had different clutches for the transmission and the PTO. Some vintage tractors had final drives, or extra gear reductions at the wheels that might have increased torque for pulling power.
Unfortunately unless a person is a expert in vintage tractor mechanics you are kind of guessing. On the case tractor we used, the PTO shaft would spin free when disengaged. This meant the clutch was not involved. By jacking it up I could depress the the clutch and by spinning the tire I could spin the PTO shaft. Take it out of PTO and it stopped. Take it out of gear and it stopped. Shifting gears made the PTO spin at different rates even just turning the rear wheel by hand. That was a scientific as I got.
I think there was some luck involved in finding the case VAC (late 1940's?) It turned out to be a good size and weight, with good tall but narrow tire. A tall tire works well for ease of pulling. I think other tractors form that era might work equally well, but I wouldn't know which to recommend. I hope this helps, Donn
Hey there,
Your question isn't answered on the DAP forums but there is a more thorough conversation (link is external) about the forecart then is present here.
Hi Annie - I'd love to see that poster! I am planning a similar project.
Yup - part of GreenStart's mission is to make its work open source - and we have a focus on documentation this year. I think a Farm Hack event would be a good idea - probably mid-summer. There are a number of tools coming along that would be fun to work on- including a new roller crimper inspired by the ADA bio folks that I am particularly excited about.
Wow, awesome. Do you have funding through GreenStart for this? If so, could you talk about that?
Are you considering opening the build of the processor to the public? If it's happening this summer then I would love to come out and learn first-hand the process of fabricating it.
Funny you should ask about more documentation. There is a LOT more documentation coming for this tool really soon. I have detailed process flow diagrams, parts lists with major suppliers and will be doing a video with operational instructions which I hope to complete this summer. I also have performace data and will be able to post the arduino based temperature data logs up and running again in its new fancy enclosure. I will also be building a new modular processor which I will swap out for the existing static mixer/tank. This change should drastically reduce the price of the whole unit by eliminating the need for the co-generation unit for heating the oil and running the air compressor. The new unit will be a smaller diesel direct drive air compressor and hydraulic power unit to run the air operated pumps and two metered hydraulic drive pumps for a cavitator type processor which should work at ambient temperatures. Thanks for your interest and will post more as soon as I can!
It would be great to see this system built at different scales and variations.

Weird. Is there a way to put it back?
CAN WE ENTER INTO AFFILIATIONS?
Which tool are you asking about? I think your post got decoupled from the tool wiki
I will have to give FreeCAD a try. It may be a good option. I primarily use sketchup because it was accessible and free. I have become comfortable with it, models are easy to share, and I can export to CAD if I need to. Some of my buddies work in solidworks a lot too, but I have not tried that yet either.
I think that maybe a stand alone wiki tied to the getting started page & tool template might be a good way to start to document CAD training resources, techniques and tips etc? Other ideas?
Thank you for participating in the Food Systems Hackathon at the NOFA-VT Winter Conference! This email contains some important information about how you can stay involved after this past weekend's hackathon. A special thanks to all of our sponsors, producers and partners:

Vermont Digital Economy ProjectThe Vermont Council on Rural Development's Digital Economy Project is looking for volunteers to assist in the building of WordPress websites for nonprofits and other organizations that provide essential services to their communities. Email Rob Fish <rob@vtrural.org (link sends e-mail)> to get involved. This past weekend, this team made progress on a new website for Seedfolks Farm (link is external) in East Calais.
</td>Making this more clearly incorporated would be great--where on the site might it belong?
You could make a tool that is "CAD tutorials".
To other, more experienced users of FarmHack--is that the best way to organize such information on the site?
I recently downloaded FreeCAD (link is external), an open source CAD software. Does anyone have experience with it? What are its limitations?
Dorn--why do you choose SketchUp over CAD? Do you find that it has enough functionality to do everything you need to do?
There are still free versions of sketchup - but they are harder to find on the site because they don't promote it.
Options are Sketchup Make or 8. Here is the link
http://www.sketchup.com/download/all (link is external)
Google doesn't own SketchUp anymore unfortunately.
I have not tried the new SketchUp Make version, which is the free hobbyist version, but the standard SketchUp Pro is now USD$590.
I think one of the best applications for starting out with CAD is TinkerCAD, owned by AutoCAD, it is very basic and only useful for basic items, but it will get you started.
AutoCAD's 123D application is one step up from TinkerCAD, but also more useful and a pretty natural progression from TinkerCAD.
I agree 100%, CAD tools are one of the biggest barriers to 3D printing becoming more common and useful.
I think a place on the this site to allow folks to post links to tutorials that they have used and found useful would be a good first step.
Great idea - for reference I attached a screen shot of what I think we are both talking about.
Anyone out there want to tackle this, or come up with a way to accomplish this in another way?
For communicating and sharing design elements I have found sketchup really helpful.
We have had sketchup introductions as part of some of the events and I agree it would be good to emphasize how helpful it is to get drawings done of the project. It is nice that these can also be so easily embeded.
I started a 3d-warehouse library here with farm hack models and related components - but this could be greatly expanded and more clearly incorporated into the site too.

One thing I have found problematic with CAD is the cost. Certainly there are free resources out there, like Google Sketchup, but I have found dimensional drawing on it is problematic. It is certainly not as useful as AutoCAD, but of course AutoCAD is prohibitively expensive. What are you using to make drawings?
Funny you should mention this - I have been in touch with Alec Ellsworth who is organizing a student club already, and I think they will even have a budget. chriscallahanuvm ( http://farmhack.net/user/805 (link is external)) is working with Alec to get this kicked off. I will suggest that they put some info onto the UVM open shop. It sounds like it is prime time for an event on UVM campus!
Dorn,
Sorry I never got back to you. The Open Office and Excel versions are now both obsolete. The current version is Google Sheets. I have a working copy that I can share, but there is a newer version in the works. Anyway, here is version 0.2: https://docs.google.com/spreadsheet/ccc?key=0Ar4Ct8viQWP7dG94VURNbERTeFRpNXphRTZRbjJnbXc&usp=sharing I haven't made detailed instructions yet, but the description above is still accurate. Please let me know if you have any questions!
Bill
This sounds like a fantastic idea -get 'em hooked on hacking while they're young. And maybe help shift the mindset of institutions they are a part of from one of top down technology transfer to collaborative innovation! If some thought were put into how this could be implemented I might be able to entice students at Cornell...
Cheers, Jeff
Hi Mary,
I sent you an e-mail, but I think it may have ended up in your spam folder. I would definitely be interested in working with you. If you are still interested, e-mail me at bladdcawthorne@glynwood.org.
Bill
Where do we start?
Daniel,
Great pictures; it looks like it's well under way. One thing I can't quite see is how it is actually rolled up and down. Do you just have a person at either end and roll it up like a rug, or are you thinking about something with ropes and pulleys, for example?
Bill
Hey there,
Seems like wikipedia-style in-text links would be the tool for the job in allowing comprehensive documentation of both tools and components of tools. There must be some reason that this isn't practical to set up from a programming standpoint. Seems like otherwise more orgs. would have their own wikis of this type. Can anyone weigh in with some of the technical barriers to using this technology?
Thanks!
