Ironworker

From looking over the plans for the CEB press it appears that an ironworker and a torch table would be helpful but not essential

Open Source Ecology Prototypes

• The goal for the second prototype was a 90 ton capacity. They budgeted a total of $6,300 for their prototype in 02/2012 ($627 for hydraulics, $1430 for tooling, $250 for fasteners, and $3,783 for steel, and $250 for material overruns)

• Their goal was to develop a 100 ton model so they designed a model with a calculated force of 130 tons as a factor of safety to account for errors: https://wiki.opensourceecology.org/wiki/Hole_Puncher_Calculations
  • A new model with this force appears to run about $23k and a used one around $14k
• It looks like the documentation for Ironworker 3 isn't complete but we may want to check on this and if model 3 operates sufficiently well

• Google docs spreadsheet: https://docs.google.com/spreadsheets/d/1z3yGJZ-21ouMC7EL49d2VH7eecRXuyXF43kfw9S4yb0/edit#gid=1
• Sketchup file: https://wiki.opensourceecology.org/wiki/File:IronworkerI.skp
  • Somewhat helpful but is not complete and is not very detailed

I don't see a cost estimate for this model, only what appears to be an incomplete list of materials.

I messaged OSE about this version and he said that "The ironworker has been built and tested, but not documented well. We took it to desructive testing, so it's not a machine that we are currently using."
