what size pres sin your videos

hello Ed,

what size is the green press in your videos? I am in the process of building a press and was thinking of doing around 30 ton press. yours looks like it moves metal pretty effortlessly. i have access to large I beam and buddies who do industrial type welding so doing the build should be no problem. Thanks Pete

My press is adjustable 25 to 30 tons, and most of the time it's set to about 25 ton. There are times when I wish for more tonnage, but those time are few. Unless you have a special purpose in mind like making huge loafs of damascus, I think that much more than 30 tons will cause more problems than it solves. Those problems being wanting to get too much done in a single pass......especially if your working with damascus. You can wreck a billet of damscus quickly by pressing too much at one time...the lower tonnage press will keep you from doing that. I always kinda chuckle when I read that someone is going to build an 80 or 100 ton press, because in their mind, they are thinking "I can get so much done with a single press!". What really happens is that a lot of billets get wrecked before they understand that their trying to do too much, too quick. If you have a specific need to high tonnage on a press, and understand it, then I say go for it. Otherwise its best to stick with 30 tons or less and you'll be doing yourself a favor.

You do not have to be doing damascus to ruin steel with a high tonnage press. I have a 50 ton and it will literally tear a piece of steel apart if you try to press too much at a time. Though I like having the pressure when doing big billets I rarely get the pressure over 1000psi on the gage when doing most work.
