I picked up the Ripsaw mentioned earlier. Photos below. It's missing at least the guide beam and assemblies that secures it to the log. Anyone that knows where I might be able to purchase these or have advice on making them would be appreciated. The saw that came with it is a Stihl 38AV. I don't know the condition of it as there wasn't any fuel to try it out. Hopefully I can get it to run. It does seem to have good compression though.
