[Stoves] Tau Stove Construction Photos

[Crispin Pemberton-Pigott]

Dear Friends

 The latest manifestation of the Lion Stove is in Lesotho and is called the
Tau (SeSotho for 'lion').  As a reminder, it is an institutional-sized stove
with counter-flowing preheated primary air made from solid bricks. The
performance in Swaziland indicates 8.8 kg of food cooker per kg of dry fuel
burned when the operator is experienced.

There is (temporarily) a set of photos available showing the steps to follow
to make one on the New Dawn Engineering 'projects' sub-domain.  At the
moment there are no dimensions posted but these are available to the needy.

will let you download the pictures one at a time (thanks Jeremy for the
indexer). They are not small files because this is really pre-publication
material.

The use of bricks with 3 holes in them is not recommended but sometimes that
is all you can find.  We had some solid ones produced by the local brickyard
(very good face bricks).  The outer shells are cheap local bricks made by
the roadside.

A drawing of the steel frame and the mould for the slab is available.  The
stove is suited to a No. 25 cast iron pot (70 litre).  If you wanted to put
a different upper section on it to accommodate something else, no problem.
The lower portion is the interesting bit.

Best regards
Crispin
