   From your description I picture a free air flow stove, something like a Franklin. These are no more efficient than fireplaces and function about the same. For something a lot more efficient if you have the materials and skill why not just build an Airtight Stove? Earthstove and Vermont Castings are two popular brands.

   A visit to the library or your local store will show designs. Some sheet steel, a little cutting, some firebrick and you'r off and running. To fancy it up add a thermostatically controlled air intake.

   These really aren't a big deal. Properly done the only hazard is to combustables you get too close to the stove. Put heat shields on the walls and a brick hearth and that problem is no more.

   Heating shop with used woodstove. Welded steel, Frontier brand, out of bussiness. Fresh air intake on bottom of stove with a inner box in the stove that has some holes at the bottom of the sides to let fresh air in or hot air out ? It works faily well as a insulated wood incinerator, lots of heat up the stove pipe. Want more heat in shop or slower burning. Anybody know of this stove and design? ( They were pretty proud of it as there is a huge patten # on the front of the stove above the doors)
   I am thinking of cutting out the inner box and putting in a shelf to deflect the heat and flames, keep them in the box longer. I have seen this on many woodstoves. I am wanting to know about woodstove theory so I can put the shelf in the right place, make it the right size, maybe cut some holes in it (as I have seen done in other woodstoves) etc. Any body have any ideas?
   Thanks LVC
