The bottom die has holes drilled into it so I can insert a set of thickness stops. I have a large set of flat dies I use for pattern weld billets. This is quite helpful when make Type M axes. I even made a lateral drawing die that is on an angle for drawing axe blades out sideways. Everything from drawing dies to beveling dies. I’ve been able to create a variety of dies that serve different purposes. It is quite easy to over forge a piece of hot steel. I really have to watch how much I move the control valve lever. I find it is a little slower than this but not by much. According to his book, this creates a ram speed of 3″ a second. The power pack includes a 16 gpm two-stage pump and a 7.0 HP motor running at 3450 rpm. Batson, a 5″ cylinder operating at 2,500 psi will generate 24.5 tons of hydraulic force. According to Build Your Own Hydraulic Forging Press by James L. Too much pressure will lead to damage to your press and even injury to the user. This allows you to precisely set the control valve.
It is critical that you have a guage as a part of your system. Prior to putting the press to use, I filled the reservoir and set the safety relief valve on the control valve at 2,500 psi. It is acceptable to use mild steel for dies, but I opted to use 4140 for added durability. Also, pictured are my first set of forging dies. Below the scale shield (not pictured) I put a cover that protects the whole front of the press below the scale shield. This was not absolutely necessary since the ram frame moved up and down quite smoothly and in line with the guide, but I wanted to make sure there was extra support to prevent any twisting and warping of the frame (Left Picture). It was made of 1018 mild steel which provided for a small amount of flex while at the same time limiting the movement of the cylinder. I installed a support bar to limit the lateral movement of the hydraulic cylinder.
