Thank you for the information.
I am currently building a Side Blast Forge with a Super Sucker Hood. The forge is water cooled, see the tank to the left with hoses attached. The blower is now on top. The Tuyere controls the air with a ,Guillotine. The gate ,leaks enough air to maintain the fire. A hand crank blower can be added to replace the power blower for fine work such as billet welding.
This forge is made with no part weighing over 50#. The Hearth is a Mark Aspery design. However, the Water Tank is connected to the Tuyere with a top and bottom hose.
I also have a stationary forge that is traditional bottom blast. I can make a deep fire in this forge. This forge is set up with an electric blower plus a hand crank blower connected in parallel to the electric blower. I have had good luck welding 1018 and A36 steel in this forge. I haven't tried a stack of knife steel in this forge.
My hope is the Side Blast forge will work better for welding because the clinkers will drop below the air blast.
I have a small amount of Blacksmith coal. Most of my coal is from house basements left over from when they burned coal for heat. Some of it is stoker coal but most is in baseball to football size chunks. I take the chunks and line then up around the fire. Then the stoker coal or blacksmith coal is piled up inside the ring of chunk coal. As the chunk coal heats, it will look greasy when it is ready to break up using a Coal Hammer. Then, it is fed into the fire and more chunk coal is placed around the fire to repeat the process.
I have found that by placing a large flat piece of chunk coal on top of the fire, the fire below the chunk gets much hotter. I tried placing a sheet of steel over the fire and got the same results, a hotter fire.
I just got the Shatto & Son 25# power hammer running. The power hammer is located about 6' from the forge. So, after the weld is set using a hammer and anvil, the weld can be finished using the power hammer. DOES ANYONE HAVE INFORMATION ON THE SHATTO & SON HAMMER?
My plan it to place an anvil directly in front of the forge so little time will be lost from fire to anvil. A second anvil will be placed conveniently for all other forge work.
