Squishing hydraulicly as opposed to the pounding Black Smiths previously employed. The neighbors would run over complaining about pounding noises. Fascinating!
Exactly! Not only the working space is too wide (thus producing high moments to bend the H beam's flange), but the guide plates are not long enough so they pinch the beam and bend it. This press would need some parts to be reconsidered. The middle die works fine but the two other one...
Just purchase dht eplans for the press, it would be very helpful if you had a cut list or parts list. I am having a hard time figuring out the part I need to get cut in bulk.
you weren't kidding that you were almost done editing! question for ya, did you say 8" stroke? i'm looking at the amazon link in the description and don't see one with an 8" stroke. also, "ask me how i know" when talking about ruining metal made me lol.

We did a 6 ton log splitter build last year, which allowed us to make some of our first damascus billets 👍🏼 but 6 tons is not much compared to this guy. A log splitter usually deflects a lot more than something like this press, too
I currently cannot find that motor elsewhere. The important parameters are that the motor is 5 horsepower, that the RPMs of the motor match the RPMs of the hydraulic pump, and that the face of the motor can accept a mounting plate for the hydraulic pump. Others have used 3hp motors with success as well, but we stuck with the 5hp model
@@FormulaJake it's not strictly necessary that the motor face accept a mounting flange. Alternatively you can design a flange to come up off the machine frame to hold the pump. Admittedly I'd rather have the pump straight to the motor face but I've been having trouble finding motors and pumps that match.
Thanks so much for the support brotha 🤙🏼 we estimate that it weighs about 800 pounds. Due to the cylinder and motor being mounted at the bottom, the center of gravity is very low and it is relatively easy to push around on a concrete floor. Otherwise, a forklift or a pallet jack would be handy.
I appreciate what your trying to do here but your not ready to start offering plans for sale to others. You need to have an engineer do the load calculations for you, you obviously haven't done them yourself. Your uprights may be strong enough but your top, bottom and carraige are not. You have no safety factor built into the press design. You need a minumum safety factor of 3 for that press to stand up to the abuse people will throw at it (more is better). The carraige guides should be atleast 8" long. 1" a36steel has a tensile strength of 36000psi, your press is putting out close to 50000psi. The only thing keeping it from bending is the die plates. Take out the die plates and test your press. If you took a piece of 3/4" steel and placed it (on the corners) in the center of your press, about an 1" in from the front edge and applied full pressure it would bend your carrage and upper die plate. Try some testing, move that 3/4" piece to the each side and apply full pressure. Your carraige plates will start deforming. Do these things with various material sizes a couple thousand times and see what happens. Think of everything a customer might do and make it twice as bad. Your on your way to having a viable plan but this press is not ready and selling plans is dangerous. I'm not making any of this up, have the calculations done. The loads are more than axial, oblique and eccentric loads can cause pressures up to 3-4 times the presses output, think levers. I mentioned this to you when you first finished it. Hopefully no one gets killed building this press.
I've done quite a bit of hand calcs and even some FEA on the press, and the factor of safety exceeds what you recommended for yield strength. I don't know why you mentioned the tensile strength of A36 and compared it to the press output; you didn't factor in the area portion of the steel. Comparing these two numbers at face value says nothing. We have done months of testing, including offset loads with and without die plates. The guides could definitely be longer, but when loading the press in the center of the die plate, it functions just as it should. Using the side dies is not advisable for any serious loads, as mentioned in the video. I agree that there could always be design improvements, but I think it is a gross exaggeration to claim that the press will hurt someone.
A+ for effort. F- for safety. I'll regretful say that you will know this when people who follow these instructions end up maiming themselves or just out right dying.
There's no such thing as "light" drawing work on a hydraulic forging press. It will go to 25 tons full pressure on every stroke, thats what they are designed to do. At 3000 psi this press will do 30 tons. You designed a wide opening press that the industry uses for multi die setups. Not every person using it will have watched your video warning them about the dangers of using your press in certain situations. Thats why you have to properly design it with strong enough materials to handle anything the customer puts between the carraige and top plate. Its not optional or conditional, people are putting their trust and safety in your hands when they buy plans from you. I'll give it to you, your really standing behind your design despite it being structurally unsound. Anyone with press/machine building experience or an engineering background will tell you the design needs seroius rework before being sold to the public.. Its not them I'm worried about. It's the people that have enough experience to follow your plans and build it but not enough to recognize the structural issues you so clearly demonstrated in this video. You could have atleast told people that the press is only designed to have a single die that is center mounted because the guide system isn't designed to survive using outer dies. Not that is enough. If you were trying to prove that the press is a good design by filming use of the outer dies it was a big fail. The carraige was racking more than the bolted guide plates should have allowed which means they were being bent and deformed. Zero safety factor, they can only survive being deformed past there yeild point so many times before something breaks and bad things happen. At 25 tons loaded up its seriously dangerous. I know you don't honestly believe your design is sound, do something to fix it. The carraige should stay parallel to the top die plate, thats the whole point of the design. If you had been forging a thicker piece of steel you wouldn't have had the dies on the opposite side to stop the carraige guides from being damaged further and probably tearing themselves apart. You know you could break this press in an afternoon, heck an hour yet you keep promoting it. I hope everyone of your customers is a top notch welder. That might save their lives, or atleast a serious accident. Advertising ways not to break it by making arbitrary rules on how the outer dies should be used "carefully" is not a solution. It's a big red flag and just dangerous. Why not use thicker material to make guides that are MUCH longer and use more of the H beam cut at an angle to support them. You'd have a press design that might work, instead your sticking with a prototype design that doesn't. The press needs redesigning, come to terms with it and help the customers that have already build your press to refit a proper guide system and strengthen it. You really should take it to an engineer so the whole thing can be gone over and get all the problems identified. I'm just focused on the biggest one. I know you care about your customers. If the press was for personal use i would have pointed out the problem and moved on but your selling plans to the public. Its irresponsible and dangerous. Please do something before something happens that you can't take back. I'm not the only one thats pointed these things out. You know I'm right, fix it.
I mean in the nicest way, as someone who isn't a engineer and is just watching to gain knowledge can you put what u said in a simpler way that I will actually be able to understand 😂
Just finish watching the video series in full... thank you very much!
Squishing hydraulicly as opposed to the pounding Black Smiths previously employed. The neighbors would run over complaining about pounding noises. Fascinating!
Awesome, one of the coolest projects.
Please recommend protective sleeves for all high pressure hoses! These can be a life saver and/or a shop saver around hot metal!
Good call! I'll be looking into this for sure, there is a ton of hot stuff that could easily melt it away 👍🏼
Pretty cool looking press, looking forward to seeing the coming videos.
Thanks! We have a pretty cool knife project coming out in the next few weeks. It'll show off what the press can do 💪🏼
Damn the ibeam is getting bowed like crazy.

Crazy seeing how much the I-beam flexs when using fuller dies
Nice!

Read what is printed on this guys shirt. That will explain a lot.

Darn, they must have changed the link. I just opened it and it says 4 inch stroke which is not correct. I'll try to find the right one!

@@FormulaJake right on brother. I got me the plans so I can mentally prep for the spring... hopefully I'm squishing steel by this time next year
Thanks so much for the support 🤙🏼 feel free to hit us up if you have any questions regarding the build! Best of luck brotha!
Chief cylinders are also available at Northern Tool and Grainger.
Can you mount this so the ram goes down instead of up?
Whats the advantages over that?
@@jacobdillon3635 stability with heavy objects. When you need a uniform squish, you don’t have to move it up with your press
Does a hydraulic log splitter have enough power to do this? Thanks

@@FormulaJake thanks man. Makes sense
With this model of Leeson motor unavailable, what do you recommend in its place?
