New world scythes require fairly sophisticated heat-treatment, to harden the cutting edge via Martensitic transformation. Old world scythes are work-hardened in the field, using a peening hammer and a small anvil to harden just the part of the edge currently in use. I'd recommend the latter. >What does it take to create a nice scythe blade on a local open-source scale?

Personally, I would've gone at it with a scythe - I mow about an 8-foot swath w/out any mechanization... but that does look fun! Do y'all have OS scythe designs up? What does it take to create a nice scythe blade on a local open-source scale? Awesome!

Make replaceable Box type steel bar lathe ways that can be bolted down to a steel frame. The frame can be fabricated using structural steel and no welding is involved. Use two heavy gauge I beams as the platform for the lathe ways. To increase torsional resistance and damping characteristics bolt multiple sections of Wide Web I beams in between the two main I beams which serve as the platform. In the spaces between the reinforcement I beams place sand bags. The steel bars which function as the lathe ways are then bolted down to the main I beams. What do you think about it? The carriage can similarly be made from thick section steel plate. Hi there marcin was thinking a lot for your lathe and I have an idea.
