it’s funny: by coincidence, I just an hour and a half ago assigned the task to engineer and design a chopper like this one to two of my students as their engineering project.
I looked at this design a couple times already and I was always impressed by its simplicity and efficiency, but simultaneously rejected by its endangering nature. So one focus of their task will be to make it safe for the user (big issue in Germany!). When it is finished and turns out o.k., I will post plans and pictures (not before the summer, though…)
I found a manufacturer (if I’m correct, in the Czek Republic)
I figure this chopper is at least twice as fast as Waynes chunker!? Wayne, what would you say?
And the built-in sacking is neat, too, me thinks.
I have a question to the community:
Would this chopped wood in the pictures (at http://en.stepkovac.com/stepka/) work in a WK gasifier, or would there be a lot of bridging going on? The thin pieces turn out to be rather long.
Thanks for your opinions!
Sam (who is still looking for a good and cheap source of scrap wood…)
