Hydraulic shop presses are indispensable tools in auto mechanics, metalworking and fabrication shops. Used to compress metal into your desired form for numerous tasks like separating rusted parts from bent ones or crushing oil filters.

This hydraulic shop press plan offers maximum versatility in terms of height and power source. While a hydraulic jack would work best, other force sources should work just as effectively.


Hydraulic presses are essential tools in any auto repair shop or workshop, whether personal or professional. With the appropriate press in your toolkit, removing and installing auto bushings, bearings, U-joints and more will become much simpler and less time consuming.

Hydraulic presses come in various sizes and types, yet all operate similarly. Their hydraulic pump generates force that is transferred through a cylinder to shape materials being formed. The hydraulic pump may be manually, pneumatic or electric depending on its application or size of press.

The pump contains a reservoir to store hydraulic fluid. It connects to the cylinder via hoses that carry fluid back and forth; these hoses are constructed of durable materials capable of withstanding high pressure and heat created by hydraulic presses.

Once activated, hydraulic pump fluid flows through a small piston (plunger cylinder) before entering a larger piston (ram cylinder), whereby mechanical pressure is distributed through an anvil and transferred directly onto a workpiece for shaping.

There are various types of hydraulic presses, each offering unique advantages and uses. For instance, an H-frame power press can easily accommodate larger loads than C-frame presses due to their box-type frame that improves rigidity and resistance against deflection - increasing tool life and job operation precision in turn.

Hydraulic presses feature control and power systems in addition to their mainframe for effective operation, including manual or electronic pressure controls, which generate and apply necessary force onto workpieces. They may be operated manually or electronically for maximum versatility - they may even be powered by diesel or gasoline engines for ease of use!

Hydraulic Pump

Hydraulic power units, the heart of any hydraulic press, enable users to generate the enormous force necessary for compressing or shaping materials used in their shop. You can build or purchase such systems, but for optimal performance and safety it is crucial that it be appropriately sized.

A ram pump works by collecting compressed air in an air chamber (fittings #14) and using it to absorb shockwaves as each stroke begins. Once completed, pressure built up in this air chamber is released via a valve when not being used by the pump; at which time a small amount of water is also used to create vacuum and allow the piston in its cylinder to retract back into its case during this period.

There are various kinds of hydraulic pumps, with certain models designed to be more energy-efficient. Piston pumps are a popular option used in numerous commercial settings as they can transfer hydraulic liquid at high speeds while providing power for heavy-duty equipment like cranes, diggers, backhoes and loaders.

Other forms of hydraulic pumps include vane and plunger pumps. Plunger pumps come in smaller sizes that are suitable for low-pressure applications like metal forming. Furthermore, vane pumps are an integral component in hydraulic presses.

Hydraulic motors are often employed to power these pumps and can either be single or three phase in nature. Motor selection should depend on your application and operating environment; usually TEFC motors or explosion proof models are best suited.

Once the hydraulic pump is installed, its ram hose can be connected. Calibration can then be completed by watching how long it takes for the ram to come to full stroke and slowly opening and closing valves until 10 PSI back pressure builds in the delivery pipe. This information will assist with calculating how much water will be necessary.


An anvil is a flat metal surface used for setting items onto and striking them with a sledgehammer, making metal fabrication much simpler and quicker. Nearly every metalworker relies on one; they're heavy and expensive due to the tasks they're designed for; however, even homemade anvils may suffice if crafted by experienced metalworkers.

An anvil comes in many different shapes and sizes, each offering different working surfaces. The main surface, called the face, is where most hammering occurs; but other areas include its horn, hardy hole and pritchel hole for use when shaping hot steel into different forms. A horn can also be found at the top of an anvil where most hammering occurs with different diameters being useful to curve hot steel into various shapes. A hardy hole allows users to mount tools directly onto its face so they can bend or cut metal directly without taking it off and using separate tools; finally there's also its pritchel hole on its body which can be used to pierce through metal into metal without using separate tools - perfect!

An anvil's body is composed of a thick slab that's wider than both its horn and step. Its wide surface has numerous curved edges used for sharp bends in metal. A flat area serves as a cutting surface if necessary, though this should never be done on an anvil made of inferior quality steel or cast iron as this may ruin it for future use.

An anvil is supported by a series of hydraulic cylinders filled with hydraulic fluid. When you pump or lever hydraulics into a small double-acting cylinder, its piston pushes fluid through to a larger master cylinder where pressure builds until reaching an anvil, baseplate or die. Once hit by your strike, this pressure forces it down onto material being worked upon, bending or cutting into desired product shapes.


Hydraulic presses use fluid pressure generated by pumps and motors to push a cylinder at a set force to compress, assemble, draw, punch, trim, stretch, stamp, or form materials for various applications. Motor pumps the fluid into either cap end port to expand it further or rod end port for contraction; when extended piston moves downward to apply set force and heavy return springs collapse the cylinder once job completed.

There are various types of shop presses, each offering specific capabilities and functions. Which model you choose ultimately depends on your material preferences as well as its tonnage and force output; but each can help make for a rewarding experience when used appropriately.

Hydraulic presses are indispensable tools in manufacturing, offering many advantages over mechanical and pneumatic counterparts. Hydraulic presses have the capacity to generate high amounts of force while having few moving parts and taking up less space; making it the ideal press for metal forming applications as they compress material completely.

Build a simple and inexpensive hydraulic shop press in your garage using components available at most hardware stores. In addition, some scrap metal will be necessary to create the frame and ram, with steel being preferred so as to not bend under its load.

The highest-performing hydraulic presses are constructed from welded steel with rigid frames that will not bend under pressure, assuring smooth performance even after repeated use. Their frames may be joined via welding or bolts; depending on your application, rams may be mounted either on either side or underneath of them.

No matter if you work with wood or metal, a hydraulic shop press is an indispensable asset in any workshop. From flattening boards for resawing, or creating molds for casting metal casting - its uses are endless!
