Hey yall,
Ive been doing quite a bit of heavy forging at my shop lately. And have came to the concuslion its time to build a power hammer. I have looked at alot of Rusty, hammer deisgns and am going build one and the ram will be about 45 or 55 lbs dependy on if i get sq or round stock at the scrap yard. I was wondering about the spring, how long should ai get about 50 inchs?, do I REALLY need to straighten it and wat is the advtanges /disadvatge of a staright vs. unstarightened spring? The anvil will be probally 4" solid sq. or round. So will the ram , the ram will be about 14" so that when the dies are at max. height I ll have about 6 inches between em. Itll have a 1 hp motor , I got a 1/2 hp free was going use for a 25 but decied to go ahead and get bigger motor and heavier ram. I got the metal for the frame free, I got a big stack of 4x8 x 5/16" I beam Iam going use fo rthe frame and have a lot of braceing so it doesnt flex much as possible. The base plate will be either 3/8" thick- 5/8" plate depending on price of the scrap steel. It ll be anorched down to a concreate pad and a piece of plywood in between. I also got a 10" in diamater pulley gave to me and think Ill use it and thought about make the pillow blocks ( fabing em up) . I am think of maybe getting the die mounts machined or may fab em up to be sorta like the Big Blus quick change die system. I am going today or tommorow to go get the anvil, and ram and the plate for base plate. Ill post pics as I buil it. My cousin is going help me build it ( who is a welder for a living) at his shop where we can use his big mig, stick , tig, and plasma. If needed and also where we will have room for lay out. We will be starting building it June 28th, but going ahead and getting all the materials all together.
