Very nice job. It's been almost 5 years so how was the performance? I noticed a few critical errors I'll point out. To press 50 ton the 6" channel should of been 8" with a max span of 34" inches between the supporting rounds. For 50 ton the uprights should be 5/8" x 4". The top support is overkill and doesn't need to be any bigger than the table size.
I have to max the volume to hear the narration, then kill the volume to keep from getting blasted by the music's high volume. Be more careful to pay attention to audio levels when editing/compiling. Not a complaint, just constructive criticism. Love the fabrication videos guys.
Firstly , nice build. i appreciate the fact that you were being honest and explained to the viewers that this was a work in progress and you in no way implied it was perfect. I've just acquired some scrap 30mm thick plate about 800mm long, from work. that going to be the start of my home built bearing removal press. I could just buy one, save myself some time. but then again I could take my car to the garage and have them replace the bearing on the front wheel. but wheres the fun in that. I'm a metal fabricator and build huge things for a living, so why not put that skillset to use, saving some hard earned cash. also, when i did my welding certs, at our college, I was asked to fabricate and install a safety screen for our 50 ton press. I used, perforated steel sheet, fitted drawer style runners vertically on either side. micro switches that shut off power when screen is lifted and restore it when in the closed (down) position. on either end of the screen , I attached steel pulley cables going up and over the press frame on V pulleys , withe small nylon rollers above the V pulleys to stop jump out. the other ends of the cables were attached to counter weights , made from capped off steel tube , filled with sand to adjust count balance. these ran inside larger diameter tubes fixed to the rear corners of the press frame to avoid any one being hit by a counterweight. hope this helps.
A nice wide width which is handy for fitting in bigger stuff but the price you pay is deflection, but if you just make another base frame the same and sit it on top that's that problem solved
That is a fairly wide press. Spreader plates 3/4 thick and 24" wide, top and bottom, would give a lot more rigidity. The right hand cable is getting more leverage than the left hand cable because it is pulling further out from the winch.
Excellent Video! Thanks for Sharing! PLEASE don't take this in a negative way...please consider installing a "safety shield" for deflecting flying parts! Maybe a steel plate of sorts? I have had steel get in a bind while pressing... and it turned loose QUICKLY! Before I could even blink, it hit my hand! Could have been a real BAD Situation! My hope is that I can help AVOID that happening to someone else.....ok, "Safety Gus" is done!..lol. I just found your Channel btw and really dig what you do! Looking forward to seeing all your videos! Have A Super Week!.....*Gus*
If you run an independent cable to each side of the table then it wont tilt on you. You can use the same winch, just mount it to a fixed position with both cables going to it. Then you can have an arbor plate or something on one side of the table and not have to worry about it when lifting or lowering. When adjusting the table it may still tilt a little while lifting or lowering due to the cables being different length or on a different lay on the winch, but it will only be a little till the other cable gets tight, then you just go past the hole where you want to pin it then insert pins and then lower.
I really like seeing special projects like this. I know you have observed the bed deflection and there are a few comments about it. I am not sure why you decided to make the bed design different than the header - both have almost identical forces. To improve the bed rigidity (you REALLY need it for safety), you need a deeper structure especially with that span. You also want enough lateral strength so it does not bow forward or backward should it start to fail - failure will occur faster than the eye can see and faster than you can react.
@@bobmarwood4232 Connecting the bed pieces will help, but the connection needs to be 'structural', not just some bolts or such. And you need to consider that sometimes it us useful to use empty space between the pieces. But the main issue is vertical deflection in the current design, because the bed will deflect much easier than the header.
Hate to say it fellow we all do not own a machine shop to make this all happen so go out and buy a press at Harbor Freight make easy mods. cost you less money and time plus my wife loves to be with her
The music at the very beginning immediately made me lose almost all interest in this video, but I decided to keep going because I assumed it was just some kind of opening theme or something that a lot of people on RU-vid have. But then I started hearing it again at around 30 seconds into the video and that was it. Maybe I can work up the patience to get through the rest of the video sometime in the future, but if you ask me, the music really ruined what could have been, and may have been, a really good video. But I might never know if it was a good video because of the unnecessary music. And also the huge volume difference between your voice and the music.
ScoredPiston A press like that would be a lot more than 300. More like almost 1000. Also what's the point of having tools if you just buy everything? I could buy a press but I want quality so I'm looking to build one for a fraction of the price
ScoredPiston Of course, typical Libtard thinking. Waddle over to the store and buy an inferior press that you're just going to fix later on. Don't dare use your skill and brains to make one, you may better yourself.
Making something is a priceless education. In addition a custom item is not off the shelf. In many cases the scrap bin is a bank account to be drawn on when it makes sense. This gentleman made something shared the education and therefore I am appreciative.
