fodder. It can easily be modified to cut any type of dry biomass into
smaller chips.

There is a pretty dreadful rotary chopper that is being promoted out of
Uganda - way too light to work properly. If anyone one is interested in
actually pursuing that route with a hand operated rotary chopper, please
contact me for a set of drawings for a machine that was developed as a
replacement for the ones from Uganda. It was designed by New Dawn
Engineering but is not in production at this time.

It is based on mild steel sections and car flat spring blade material for
chopping blades (the best steel routinely available in all countries). It is
not special in any way. It is based on the normal powered finger-chopping
agricultural machines.
