Blacksmithing Tips - Exactly what Kind of Power Hammer is Right For Your Store?

Blacksmith Power Hammers or Trip Hammers

If you have actually ever worked with a power hammer you see the blacksmithing world through different eyes. Power hammers really fall into 3 basic classifications, Hydraulic Presses, Mechanical Hammers, and Air Hammers. They are all created to increase the amount of force that you can apply to the steel. This suggests you can do more work in a provided amount of time and you can work larger bar. Unexpectedly this opens a whole brand-new innovative truth with the steel.

Hydraulic Presses

I don't utilize one in my store however I have actually utilized one years back in another smiths store. Hydraulics have lots of power (actually) and can force the metal into various shapes extremely successfully. They are useful for extreme controlled force applications such as requiring steel into preshaped passes away, or cutting at particular lengths or angles etc

. This is not an effect machine such as mechanical hammers or air hammers, and is not fast. It can be used for extracting steel but this is tedious. Although it would conserve time from extracting by hand and permit you to work larger bar I would go bananas with the slow process.

Essentially the device is a hydraulic ram mounted on a frame with an electric pump. You use a foot control to crush the metal. Action with the foot apply more force. Release the foot the dies back off then you can move the bar and apply the force again in a various area.

There are a number of favorable elements of a hydraulic press. They have a little footprint, and require no unique structure. Prices are workable for this kind of tool. About $2000.00 in my area. There is no effect noise or vibration with this type of machine. The whine of the hydraulic pump can be loud however it does not have the same annoyance element for next-door neighbors as the effect from a hammer. Presses are ranked by the variety of lots pressure that the ram can produce. 20 heap, 40 ton and 60 lot prevail sizes.

Mechanical Hammers

All mechanical hammers work on a variation of the very same principle. A turning crank shaft raises the weighted hammer head that is counter well balanced, then requires it down on the next half of the revolution. The attachment on other hammer head needs to be a spring building and construction of some sort so that the impact is soaked up in the spring not the crank shaft. The counter weight eases a few of the pressure on the motor.

There have been many different setups of mechanical hammers over the years. Little Giant enters your mind however this is only one design. Others consist of Helve Hammers etc. Mechanical hammers are rated by the hammer head rate. So a 25 pound 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 bigger the motor that you have to run it.

Something to think of. If your store remains in open air but has no electrical power you might run a mechanical hammer off a little fuel engine. A little pricey but compared with the amount of work you could do this way, it might be worth it.


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

The appeal of a mechanical hammer is that it is relative simple to develop or fix. The ideas of the movement are really basic and easy to follow in slow motion. Mechanical hammers were fairly typical in industrial settings in the late 1800's and early 1900's so you might have the ability to find one for an excellent price in your location. The drawback is that parts may be impossible to discover and you may need to fabricate your own.

You can also construct your own mechanical hammer. It will take some tinkering but an excellent working hammer can be made pretty economically. They do not take up a great deal of area. Maybe 2 feet by 3 feet for a small one. They are a bit loud to run and have an impact noise to them. They do require a great structure, although a little one can get by with a small foundation. They are a bit restricted by the tasks that you can do with them. If you are innovative with your tooling you still can do a lot of work and conserve your arm.

Air Hammers

My personal favorite. The air hammer was originally developed as a steam hammer for huge industrial applications. Like the mechanical hammers they are rated by the hammer head mass, and usually range from 50 lb to 1200 lb or more. The upper end of the scale are enormous devices that need mammoth foundations to work appropriately. These are poetry in motion to enjoy an experienced smith use.

The principal behind the air hammer is fairly merely. Air pressure raises a weighted hammer head then some thing shifts the atmospheric pressure and the hammer head is dropped under atmospheric pressure force then it is raised 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.

Most smaller blacksmithing stores utilize 50 pound to 150 lb size. There are 2 subclasses of air hammers that you should know. The self consisted of and the air compressor version. The self consisted of utilizes 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 tired or sent in differing total up to the hammer head cylinder. This provides 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 constant line pressure and has a feed back circuit developed into the design. The hammer head travels up and trips a switch that informs it to return down. Once it reaches a specific travel point another switch informs it to return up. The quantity of the exhaust dictates 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 in fact less moving parts and less to wear. I discover them to be more versatile. lump hammer can change your stroke and force simply by moderating your foot peddle. With a mechanical hammer you need to make a mechanical change to change your stroke height. Your force is controlled by the speed of the effect or the speed of rotation.
