[Stoves] MUST CHARCOAL BE A CAUSE FOR CONCERN?

[Richard Stanley]

re chopping machines,

I'd also like to mention our own thresher masher chopper (TMC) shown on our website <www.legacyfound.org>.  A detailed construction manual and a how to operate and maintain manual is available thru the website. The physical machine is being made in Arusha Tanzania and Kampala Uganda if the manufacturer is still there: We're open to assisting others to set up their own manufacturing base as well.  Its hand cranked but its ver different to the design you are referring to Crispin.

The TMC chops but it also threshes and mashes material, rendering it especially fit for the wet process type of briquetting. The physical dimensions are about what you are showing Crispin. It is also fed from the side through a progressively enclosed tray, such that it is difficult to get one's hands into the chopping blades. As to feed control for safety, it is designed with an inbuilt stop to  chop only about a one inch maximum  length--no matter how hard you try to force material thru.... It also has an internal chamber which is fed from a hopper on top for the latter threshing and mashing functions.

Aluta continua,

Richard Stanley
