Sat. & Sun., May 7 & 8, 9-4. Build a Propane Burning Blacksmithing Forge and Make a Knife


Create a blacksmithing forge from a used propane tank, metal stock, and high temp. refractory cement. 10 PSI burner with black metal pipe gas/flame delivery system. Involves cutting, drilling, and welding (we do that) metal. Create mold and pour cement. All materials provided. $295. A day and a half of knife making with this class (not sold separately). For forge & knife making weekend package: $375.

A finished propane burning blacksmithing forge. The side ports are for feeding your metal project into the forge. A variation of this design can produce a metal casting furnace. The sides of the tank are left intact except for your prop hole is cut at the top of the tank. This allows metal to be fed into a crucible positioned inside the furnace.
The tank is cut and welded. Leds are welded to the tank. Three lugs are we;ded on both the perimeter of the top and bottom. Screws with wing nuts serve to keep the top and bottom fastened together.
The black metal pipe at an agle is where the ignited propane creates a vortex for the heating of metal.

This large version of the forge has the welded lugs at the top as well as shelf extending out from one of the heating ports; this allows you to selectively heat your project.

High temperature paint is applied after the propane tank is scraped of tags and labels.
Refractory cement is poured into the tank before a Sana tube is cut and set into place in order to pour the cement sides of the tank.
Cardboard and duck tape serve to create the form for the refractory cement. We will be using Sana tube and styrofoam  instead of cardboard.
Refractory is worked into the sides of the Sana tube and the port forms.

This fixture allows airflow to the propane gas flame.
This is actually a metal casting furnace variation of the design.
