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

Blacksmith Power Hammers or Trip Hammers

If you have ever dealt with a power hammer you see the blacksmithing world through various eyes. Power hammers truly fall into 3 fundamental categories, Hydraulic Presses, Mechanical Hammers, and Air Hammers. They are all created to increase the quantity of force that you can apply to the steel. This means you can do more operate in a provided amount of time and you can work bigger bar. Unexpectedly this opens a whole brand-new creative reality with the steel.

Hydraulic Presses

I do not use one in my shop however I have actually utilized one years back in another smiths store. Hydraulics have tons of power (literally) and can force the metal into many different shapes really successfully. 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 machine such as mechanical hammers or air hammers, and is not fast. It can be utilized for drawing out steel however this is tedious. Although it would conserve time from drawing out by hand and permit you to work bigger bar I would go bananas with the sluggish procedure.

Essentially the device is a hydraulic ram mounted on a frame with an electrical pump. You utilize a foot control to crush the metal. Step with the foot use more force. Launch the foot the dies withdraw then you can move the bar and use the force again in a various spot.

There are a few positive aspects of a hydraulic press. They have a small footprint, and need no special foundation. Rates are workable for this type of tool. About $2000.00 in my location. There is wood hammer or vibration with this type of maker. The whine of the hydraulic pump can be loud however it does not have the same inconvenience aspect for neighbors as the impact from a hammer. Presses are ranked by the number of heaps pressure that the ram can produce. 20 lot, 40 heap and 60 heap are common sizes.

Mechanical Hammers


All mechanical hammers work on a variation of the exact same concept. A rotating crank shaft raises the weighted hammer head that is counter well balanced, then forces it down on the next half of the transformation. The accessory 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 alleviates some of the strain on the motor.

There have been several configurations of mechanical hammers throughout the years. Little Giant enters your mind however this is only one style. Others consist of Helve Hammers etc. Mechanical hammers are ranked by the hammer head rate. So a 25 lb Little Giant has a 25 pound 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 need to run it.

Something to consider. If your shop is in open air but has no electrical energy you might run a mechanical hammer off a little gas engine. A little costly but compared to the amount of work you could do this way, it might be worth it.

I have actually only worked a little with mechanical hammers but a 1 hp motor will add to about 50 lb Hammer head weight.

The charm of a mechanical hammer is that it is relative basic to construct or fix. The principles of the movement are really easy and easy to follow in slow motion. Mechanical hammers were relatively common in commercial settings in the late 1800's and early 1900's so you might be able to discover one for a great price in your location. The downside is that parts may be impossible to find and you might have to fabricate your very own.

You can also construct your own mechanical hammer. It will take some tinkering however an excellent working hammer can be made quite financially. They don't take up a lot of space. Maybe 2 feet by 3 feet for a small one. They are a bit noisy to run and have an impact sound to them. They do need a good foundation, although a little one can get by with a little structure. 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 great deal of work and conserve your arm.

Air Hammers

My individual favorite. The air hammer was originally developed as a steam hammer for substantial commercial applications. Like the mechanical hammers they are rated by the hammer head mass, and typically range from 50 pound to 1200 lb or more. The upper end of the scale are massive devices that require mammoth structures to work properly. These are poetry in motion to view a knowledgeable smith usage.

The principal behind the air hammer is relatively simply. Air pressure lifts 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 creates a cyclic hammering of the steel. The weight of the hammer head and the pressure of the air both contribute to the force applied to the steel.

A lot of smaller sized blacksmithing shops use 50 pound to 150 pound size. There are 2 subclasses of air hammers that you ought to be aware of. The self included and the air compressor variation. The self included utilizes 2 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 requires the hammer head cylinder up. Valving triggers the air to be either exhausted or sent in varying total up to the hammer head cylinder. This offers 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 constructed into the style. The hammer head travels up and trips a switch that informs it to go back down. Once it reaches a specific travel point another switch informs it to go back up. The amount 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 actually less moving parts and less to wear. I discover them to be more flexible. You can change your stroke and force just by moderating your foot pitch. With a mechanical hammer you have to make a mechanical change to change your stroke height. Your force is managed by the speed of the effect or the speed of rotation.
