"It's amazing how versatile it can be. I work by myself and the KA75 isn't too far from my anvil. It is truly a great helper."

The KA75 Power Hammer

Set-Up Requirements
The machine comes fully assembled with an air shutoff valve. Shipping weight is 400 lbs. It is recommended to provide a base of 400 lbs. or more for an inertia block which will give the full effect of the blow. Foundations can be metal plate or concrete. A metal plate makes the machine portable if a forklift is available. A concrete foundation 1-foot deep by 2-foot square is what most people have chosen. The machine can be set up on a 4-6-inch thick shop floor; however the concussion of the hammer may settle the sub-floor and generate cracking. Imagine hitting a floor with a 100-lb. hammer repeatedly. Also, pouring a base gives the opportunity to cast J-bolts for secure anchorage.

It is recommended to have a small air receiver near the hammer with a regulator and oiler. The machine takes air in gulps and the small tank helps accumulate the needed volume. The receiver can be fed with a standard inch airline and a inch air line comes from the tank to the machine. A quick-change coupler should be installed before the shut off valve.

"I am doing real well with the hammer. It is loosening up as you said it would. I have cut my time down in making a knife from a railroad spike to 1/20 of what it took by hand. Not only is the forging time faster, there is very little grinding. The knife dies work real well."
