The details..

'A Home Built Heat Treatment Furnace' is a guide that offers detailed instructions on building your own heat treatment furnace. The author warns readers of the risks involved and advises consulting with an electrician before proceeding. This book is specifically targeted towards knife makers, providing measurements and details necessary for creating a furnace suited for their needs.

The first step in constructing this furnace involves obtaining lightweight firebricks as well as steel sheets cut to specific dimensions. These materials are then used to construct the body of the furnace, which must be large enough to accommodate elements required for heating.

Once constructed, firebricks are fitted into grooves carved out along each side of the interior chamber where Kanthal wire elements will be placed. The two elements should be wired in series using high temperature insulated wires designed specifically for furnaces or kilns. A programmable control and thermocouple can also be used if desired.

Finally, construction of the front door completes assembly by allowing easy access when inserting knives or other items requiring heat treatment into the internal chamber. Overall, 'A Home Built Heat Treatment Furnace' provides clear guidance on building an affordable yet reliable tool essential for any serious knife maker.
