Well, I’ve decided to post a few pictures about my new project ;a charcoal tractor. The tractor is a Ferguson tea20 mechanically a near clone of the ford 9N ( or vice versa depending on your loyalties). It uses a natural gas tank (junk of course) with a gasketed top lid, exhaust cooling, air intake from the bottom. This one has a refractive lining in the bottom cast in two parts; the nozzle cast into a yogurt container with a 3/4 inch dowel for the hole then the tank lining poured around it to hold it in place. With any luck when it wears out I will pop it out and drop in a newly cast replacement. Then it enters a cyclone (thanks Stephen) then a final filter of steel wool and a spa filter in a 5 gallon bucket. Air filter is another spa filter… I’ve flared the unit but need a little plumbing work to run… Soon pic 4 is the nozzle form.
Best regards, David Baillie
