The Hydraulic Forging Press for the Blacksmith by Randy McDaniels • 200 pages, Full Color, Hardcover, 8.75' x 11.25' The hydraulic forging press is becoming increasingly important to the forging shop. This relatively small machine, which is often hand made, allows smiths to do many of the same operations as a power hammer while adding more control and expanding what one can do with hot metal. Over forty years ago a spark ignited Randy McDaniel's passion for forging hot metal. This has been a passion that continually grows. Seven years ago his exploration of hot metal evolved and he began specializing in work done with the hydraulic forging press. Randy now creates all of his own tooling and dies which he uses to produce a line of unique items.

He loves how the power of his sixty ton press pushes hot metal as if it were clay in his hands. This blacksmithing book covers the history, the how to, and especially the versatility of the hydraulic forging press for the blacksmith and the knife maker. It provides a comparison between the press and other machinery, the different types of presses, which type of press is right for your application, should you build one or buy one, focuses on tooling that you can make to get the most out of your press and much, much more.

Large, full-color drawings and photographs of presses, items made on the press, and the tooling used is featured through out the blacksmithing book and in the gallery section. Award-winning author and blacksmith, Randy McDaniel has brought together an international group of collaborators to make Hydraulic Forge Press for the Blacksmith a useful and inspirational resource for anyone forging hot metal.

I have a chance to pick up a Vickers hydraulic power unit for $250. It has a 3 phase 5 hp motor running at 1730 rpm. The pump is a variable displacement piston ranging from 300 to 3000 psi. It is only 5gpm. Would it be too slow for a hydraulic forging press? I am shooting for a 15 to 30 ton press.

This unit comes with a 5' or 6' x 18ish' cylinder (exterior dimensions). No exact specs on the cylinder but I could always get a different cylinder.

I am not an expert by any means on this and still learning alot on hydraulics. What you do have is a low presure pump. I have a H frame press which was converted with a low press cylinder 4' dia. And a 18' stroke, which is I was told about 13 ton. It is slow but by prepositioning the ram were I want it helps alot. As Grant Sarver says you can do alot with 13 ton and he is absolutely right.

I am building a 30 ton C frame high pressure but have not had much time to work on it. Grant, I have a sneaking suspicition that the o might be a Q which would lead me to think you have a 25VQ P2A, Not too terribly sure, the modle number you gave me is not lining up with any of the literature that im finding, but here are a couple of options for the 25V sieries vane pumps, hopefully one is right. And here is some info for Weld Inc's PVB5RSY20CC11, Looks like yours is a 5 GPM piston pump.

This is all that I have with me here at work, but when I get home I'll put up some more info that I have on flow rate VS pressures for the piston pumps. 5GPM is not a whole lot. The main issue that your facing is ram speed. In most typical home made forging presses a two stage gear pump is used. In this setup the first stage supplies low pressure high volume (15 or so GPM @ 500 or less PSI). This stage supplies the volume that a moderate sized cylinder capable of providing sufficient forging force needs to move rapidly until the dies contact the workpiece.

(4 to 6 inch diameter cylinder developing 24 to 40 tons with 1+ inches per second no load speed). When the dies hit the workpiece the pump shifts to the second stage. Kellogg's mission nutrition game full version free software download for laptop. In the second stage the average pump will only typically move around 5 GPM at 2000-3000 PSI depending on what the relief valve is set to. Your pump moving 5 GPM maximum will move a small ram at a set speed fast enough for forging, but the problem is that you will end up spending a lot of time waiting for the ram to cycle. The one cool thing about variable displacement piston pumps is that they are capable of moving from near 0 GPM up to there maximum rated output, therefore they are capable of building and *holding* pressures of up to 3000 PSI. In a gear type pump, fluid pressure can not be stored easily due to the fact that the pump must constantly move fluid or they will over heat the fluid and stall the motor driving the pump, therefore most gear pumps idle at about 50 PSI while constantly recycling fluid from, and back to the resivoir. Because of this, you have to wait for a gear pump to build pressure (1-2 seconds).
