Blacksmith Power Hammers or Journey Hammers

If you have actually ever worked with a power hammer you see the blacksmithing world through different eyes. Power hammers truly fall into 3 basic classifications, Hydraulic Presses, Mechanical Hammers, and Air Hammers. They are all developed to increase the amount of force that you can apply to the steel. This means you can do more operate in an offered amount of time and you can work bigger bar. All of a sudden this opens a whole new imaginative truth with the steel.

Hydraulic Presses

I do not use one in my shop but I have used one years back in another smiths shop. Hydraulics have lots of power (literally) and can force the metal into many different shapes extremely efficiently. They are useful for severe regulated force applications such as forcing steel into preshaped dies, or cutting at specific lengths or angles and so on


. This is not an impact maker such as mechanical hammers or air hammers, and is not quick. It can be utilized for drawing out steel but this is tedious. Although it would conserve time from drawing out by hand and allow you to work bigger bar I would go bananas with the sluggish process.

Basically the device is a hydraulic ram installed on a frame with an electrical pump. You use a foot control to crush the metal. Action with the foot use more force. Release the foot the passes away back off then you can move the bar and use the force again in a different spot.

There are a number of positive elements of a hydraulic press. They have a little footprint, and require no special structure. Rates are workable for this type of tool. About $2000.00 in my location. There is no effect noise or vibration with this kind of device. The whine of the hydraulic pump can be loud however it does not have the same inconvenience element for neighbors as the effect from a hammer. Presses are ranked by the variety of lots pressure that the ram can produce. 20 load, 40 ton and 60 load prevail sizes.

Mechanical Hammers

All mechanical hammers deal with a variation of the same concept. A rotating crank shaft lifts the weighted hammer head that is counter well balanced, then forces it down on the next half of the transformation. The attachment on other hammer head needs to be a spring building and construction of some sort so that the effect is absorbed in the spring not the crank shaft. The counter weight alleviates some of the strain on the motor.

There have been various setups of mechanical hammers for many years. Little Giant comes to mind but this is only one design. Others consist of Helve Hammers etc. Mechanical hammers are ranked by the hammer head rate. So a 25 lb Little Giant has a 25 lb hammer head weight. The heavier the head weight the bigger the steel that you can work under it but the larger the motor that you need to run it.

Something to think of. If your shop is in outdoors however has no electrical energy you might run a mechanical hammer off a little fuel engine. A little pricey but compared to the quantity of work you might do this way, it might be worth it.

I have just worked a little with mechanical hammers but a 1 hp motor will run up to about 50 lb Hammer head weight.

The beauty of a mechanical hammer is that it is relative simple to build or repair. The concepts of the motion are really simple and simple to follow in slow motion. Mechanical hammers were reasonably common in commercial settings in the late 1800's and early 1900's so you may be able to discover one for a good price in your area. The drawback is that parts might be difficult to discover and you might have to make your own.

You can likewise build your very own mechanical hammer. It will take some tinkering however a good working hammer can be made quite economically. They do not take up a great deal of space. Perhaps 2 feet by 3 feet for a small one. They are a bit loud to run and have an impact sound to them. They do need a great structure, although a little one can get by with a little foundation. They are a bit limited by the tasks that you can do with them. If you are creative with your tooling you still can do a lot of work and conserve your arm.

Air Hammers

My individual favorite. The air hammer was initially conceived as a steam hammer for big industrial applications. Like the mechanical hammers they are ranked by the hammer head mass, and usually range from 50 lb to 1200 pound or more. The upper end of the scale are huge devices that need mammoth foundations to work appropriately. These are poetry in motion to view a knowledgeable smith usage.

The principal behind the air hammer is fairly merely. Atmospheric pressure raises a weighted hammer head then some thing shifts the atmospheric pressure and the hammer head is dropped under air pressure force then it is lifted once again. The air on the bottom of the air cylinder functions as the cushion changing the springs in a mechanical hammer. This process develops a cyclic hammering of the steel. The weight of the hammer head and the pressure of the air both add to the force applied to the steel.

The majority of smaller blacksmithing shops utilize 50 pound to 150 lb size. There are 2 subclasses of air hammers that you should be aware of. The self included and the air compressor version. The self consisted of uses two air cylinders. One is the compressor cylinder and is driven by a motor. This cylinder provides air to the hammer head cylinder. So every up stroke of the drive cylinder forces the hammer head cylinder down and every down stroke forces the hammer head cylinder up. Valving causes the air to be either exhausted or sent in differing amounts to the hammer head cylinder. This supplies the control on the stroke and force applied to the steel. This cyclic timing is governed by the speed of the electric motor.

The air compressor reliant air hammer feeds off a continuous line pressure and has a feed back circuit constructed into the design. The hammer head travels up and journeys a switch that informs it to go back down. Once it reaches a particular travel point another switch tells it to go back up. The quantity of the exhaust determines both the speed and the force applied to the steel.

Although air hammers appear to be a bit more complicated than a mechanical hammer there are really less moving parts and less to wear. I discover them to be more flexible. sledge hammer can adjust your stroke and force just by moderating your foot peddle. With a mechanical hammer you need to make a mechanical adjustment to change your stroke height. Your force is managed by the speed of the impact or the speed of rotation.
