SOLD!
I am upgrading my own air hammer to a heavier weight, both built by David Robertson of Hammer & Tongs Studio. (go here for description)
To that end, I (HAVE SOLD) my current air hammer (Imperial measurements) :
• 50 lb head weight
• built on ABANA 'lift / drop' system (by R. Kinyon)
• requires separate (larger) compressor
This video shows me working on railing elements using this air hammer
This hammer is 'rated' for working up 1 1/2 x 1 1/2 inch stock.
I have worked material as large as 1 1/2 x 4 (admittedly - slowly!)

3/4 view |
front view |
• Total weight (approximate) 450 lbs
Closer view of working area - plastic safety shield down |
- throat clearance = 12 (back edge of die to frame gap)
- die size = 3 1/2 x 1 1/2
- total stroke height = 9 inches
(note effective working gap between the dies is really about 4 inches)
close up of the die set up |
- head block = 4 x 4 x 10 inches
- cylinder type = heavy duty hydraulic (replaced the original lighter duty air type)
- cylinder shaft diameter = 1
- cylinder interior diameter = 2
- supply hose length = 5 feet (as existing - from compressor)
- foot peddle type control, on roughly 4 foot hose (to allow for standing back when working longer bars)
Includes:
- input air control (water trap, gauge, oiler)
- full air lines (compressor to hammer)
additional die blocks made to fit this machine:
- 'Hoffi' style bottom 1/2 crown die (for spreading, seen used above)
- centre mount 'hardie hole' die block for one inch (would allow use of existing anvil hardie tools)
- centre shaft bottom die to front hardie hole (fits above)
- bolt in place front hardie hole attachment
This machine is basically 'plug and play' - fully working and ready to go.
- Requires a larger (40 gallon / 2 HP) air compressor for input air
- Air flow required is 10 cu/ft/min @ 90 PSI
It may be possible to take some of the pieces apart. Originally the bottom die block section bolted into place. This has been re-enforced with some welding - which likely could be separated with an angle grinder / zip disk. This support is made of two pieces of square tube, which I had filled with lead shot to improve the stability of the machine.
I have the machine mounted on a raft made of 4 lengths of rail tie, each four foot long. This sitting on top of four inches of sand. (All dug in to ground level).
SOLD!!
