Robert Hensarling's Forge
This Forge by Robert Hensarling is 12" diameter x 24" long, and the insulated hinged lids
open and close on each end. There is a adjustable tong rack on each end in front of the
openings, and a stationary tong and hammer rack built into the cart itself. It's easily
moved around the shop on the steel wheels, and can hold two propane bottles in the
bottom cart shelf. The burners are naturally aspirated venturi burners. Robert built this
forge to handle large "canned" mosaics, but it can also be used for bladesmithing as well.
He can use either one or both burners, and each burner is fully adjustable. When using
only one burner, Robert has a movable "wall" of Inswool "board" that he can place in
position in the forge, closing off the section he's not using. This forge is highly efficient,
and reaches welding heat in just a few minutes.
This view shows the forge body, open lid with kaowool, tong and hammer rack, cart and
cart handle. There are two stationary and two swiviling metal wheels welded to the
bottom that Robert purchased at the local tractor supply store. You can also see the
extendable tong brackets, they move in and out, up and down. The two end lids can be
bolted shut, helping seal the gasses from coming out anywhere except the center
openings.
View of the left hand side of the forge and cart. Robert uses a much larger propane bottle
when using this forge, but this shows that one or two of the small bottles can be placed on
the cart shelf if wanted. Note the handle on the front of the cart, it's really handy. Robert is
constantly moving this forge around next to different tools in the shop (BLUE air hammer,
100 pound Little Giant, Hydraulic press, anvil). All of these tools are in one area, but it's
nice to "tweak" the position of the forge for the tool he's using at the time.
This view shows the forge from the right hand front quarter side. The back lid opens just
like the front. You can see the adjustable tong holders, there's one on each end. The
opening in each lid is 3.5" x 4.5". Robert made them large enough for handling mosaic
"cans".
This picture shows a detailed view of the burner assembly and gas line piping. You'll
notice that Robert has installed an idle by-pass circuit for the gas going to the burners.
This is very useful function and will allow you to throttle the burners back when needed,
for instance Robert writes "If the phone rings, or if I'm going to be at the power hammer
or anvil for a while, I just turn the main valve off, and the bypass lets just enough gas go
through to keep it burning."
This shot shows the 3" (3 layers) of 2,700 degree inswool and a topcoat of ITC-100 applied
to aid in increasig forge efficiency as well as stabilize the fibers. The shelf bottom is a
length of kiln shelving.
