Love the press Keith. You did a great job. Love the back story as well. Im planning on fixing up mine pretty soon. I have a Dake 50 ton manual press, but built a larger frame then what it came with. I want to add a pheunmatic or electric pump to it so it will be alot easier to use, like when broaching keyways.
Thanks for the comment and I saw your message in my inbox, will read it later and get to checking out your sight, running around getting ready for the fourth and editing my next series, plan on publishing this weekend. ;{)-----
I am glad that you decided to do this series. Since I have been needing a press (looking at a much smaller model for wheel bearings and such) I have always wondered how yours came about. I would once again like to thank you for your knowledge. Robert
@billdlv The head on the end of the ram is removable, to re skim cut the face, if ever damaged or adapt other fixtures. It is secured with a 3/8" set screw...
This is another project I have planned. I have acquired a press that needs some care and have wanted to add a power setup like this. My interest in other things is fading and I'm ready to get my hobby type shop going. Got the mill running today. A big step for me! Thanks for all the tips and information!
I'm using the Seventeenth edition, but I can look it up in the 24th and let you know what page, it is on, it was in the weight and measurement area in the rear of the book, i believe. I'm sure it is one of those charts still valuable today in the average industry. ;{)-----
Pressure = Force / Area ; so, F = 3,000 Lb X 29.452 SQ IN. = 58,904 LB or 58,904 / 2 = 29.452 Tons of force. The most accurate way to measure the force of your press is to put in a pressure gauge and multiply its reading by your cylinder area (19.63 SQ IN.) For example: if you are pressing @ 1,500 psi here is the force calculation: 1,500 PSI X 29.452 SQ IN = 44,178 lb of force or 44,178 / 2 = 22 Ton of force. Super press design!!
I was hoping you would show that awsome press. My old bottle jack press I buildt 30 yrs ago looks to be replaced. Your welding positioner on prevous videos has inspired me to build one. I will be using a milwaukee hole hawg as a removable motor. Last, I wished I could pick up your radio station in N.W. calif. THANK YOU for all your videos you are becomming famous....
It could of been 2" higher, and I did weld in a inner pipe that crosses over and then downward. I have run the fluid at or as high as the return level since 1997 without any problems. Thanks for the comment and a good note for anyone building there own tank. ;{)-----
@EarthshipFreedom I feel that is such a low posiblity, at the low pressure used on my press compared to higher pressured systems, witch have had those kind of insistents, that its not worth getting paranoid...
They are held on by a series of socket head cap screws, screwed into tapped holes in each uprights, I centered the backlash and the play limits, of the frame and pinion gears so no bind could occur. With apposing gears the lift is equally loaded. ;{)---
Your press is nice...and your attitude towards machinists work as art work is impressive. We need more of the artist/craftsman values in America again. Regards, SSK
That is an old Gressen unit about 25 years old and now Parker makes the components. I use to do a lot of hydraulics and had several suppliers in Ma. but now, search the net myself, when I need something. ;{)-----
I have used several hydraulic presses, the current one is a "Dake". I believe you have done a fine job on your design. I also would choose the chain drive for the height adjustment table and really like your hydraulic feathering controls. My hat off to you.
Keith....I got to give you kudos on the press build!! Job well done........it has everything I want. Question: As I am looking to build my press soon, I find that used hydraulic cylinders fetch a pretty steep price (especially when the bore is 4 to 5 inches). Any suggestions on where I might get a good used hyd-cyclinder besides Ebay?
Hi Keith I have a Manley 80 ton press that has two pumps on it one goes up to 40 ton and then you use the other one. The cylinder on it is 5" so how did they get 80 ton from it I'm thinking of rebuiding it has a screw in the ram for quick adjustment but the thread is stripped out of the ram so I will have to redo that Thanks for your video
+Ashley Laurens -- Thanks Ashley for the info!! I take it from my research that it really doesn't matter what edition I get.....maybe something used from the 40's or 50's??
I could really use some help/advice. I'm interested in building my own hydraulic press. When I look at charts or do the calculations to pair an electric motor to a hydraulic pump, even at 5gpm and 3,000psi, I get a motor requirement of 10.5 HP. This is too expensive at this time. Can I just run a smaller motor with this pump? You running a 3HP motor, does it just make it slower than a "matched" motor would? Can a smaller motor than called for run the same hydraulic pump, just at a reduced rate of flow and still the same pressure? What makes more sense to run a hydraulic pump, and 3600rpm motor or a 1750RPM motor? I have really been struggling for a long time to find answers to these questions.
If you run a less than motor, you will stall the motor if pressure is excessive for the motor to handle, if I dead load mine it will stall and trip the over loads on starter and I have to reset them, hence you seeing me feather the top end pressure or pulse the valve control. A good quality motor will be the least likely component that will fail on a hydraulic press, don't look at it as one time cost, take the cost and divide it by the amount of years you plan on owning that press and that is the way you have to make sense of it.
@@KeithFenner Thank you Keith. The video was old enough I figured my post was a hail Mary. (And I have been looking at that video for at least two years) I'm amazed to have a response. Thanks! I also value the perspective of spreading the cost over years. Helps. What about the motor RPM? Is 3600RPM the way to go, or is 1750RPM sufficient?
@@KeithFenner Thanks again. I am finding it easier to identify what HP gasoline engine rather than an electric motor to fit to a pump. Perhaps I'm getting stuck in a wood splitter world. What are some better sites I could visit that deal directly in hydraulics, pumps and motors?
Perfect - did you make the collet for the hose swaging tool, or just the press tooling? Great video, as always. From one former San Diegan to another, thanks.
That is a thing of beauty! I raise and lower mine with my cylinder. Wondered why you went with the crank? I was like you dreaming of my dream press for years and slowly acquiring part over the years. I mounted mine on a 5x6 table, so I could position the cylinder anywhere over my workspace (still not done). But after seeing yours I kinda wish I could start over. Thanks for the video.
Dear Keith, I am building a 20 ton shop press and would like to know if you could share your ideas on gears and types of either bearings or bushings for the shafts going thru unit. Thanks for your help and ideas as they have proven useful not only on my school projects, but also on my projects at home. Respectfully, John
I just turned a 1" long slug with the right bore and welded it in place and passed the reamer through it afterward giving it more surface area and then add grease. no bushing or bearing. ;{)-----
Keith, could you please give a online reference for where you get hydraulic components like the swivel valve on your press. Keep on repairing America one project at a time!
Keith, Thank you for these videos.... I just happened to find your blog listing on the index for your videos. When I clicked on the blog .. I noticed the donation window there..... I cannot think of a more worthwhile way to help promote some basic skills for the populace than to donate to help keep your videos coming!! Thanks again!! Oh... How did you attach the Gear Rack strips to raise and lower the bed for the press... Looks like you only used 2 strips, Right rear and left front
LOL!.... I remember running a HUGE Industrial "Punch Press, for a Summer job, after High School, and that Factory had TWO Monster presses, for punching Clutch Plates, out of 1/2 thick Steel plates, about 14" diameter. They could do it relatively smoothly, quietly, and all day long. They were 20 feet tall, and 8-10 feet wide, and 6 feet deep. They were (If I remember right), 200 ton, and the other might have been about 150 ton. Anyone with a 50+ to press has A LOT OF POWER in their hands!!! Your Press IS QUITE the Machine!!!
Are you worried at all about having the hydraulic hoses exposed right at eye level?I have heard horror stories of micro streams of fluid shooting out, of course causing problems with the operator.
I was wondering why the handle was moving so much when you reached the "peak" pressure on the last vids. It's because of the chain. It hacing slack and some elasticity sort of added to the motion.
Yes!! Been waiting on this. . . Adding to my favorites. BTW, you shot yourself in the foot mentioning the bender. . . Now we're gonna wanna see that too! LOL
I'm building a press that's 40" in between up rights with 8" 3/8 C channel for head and table , and 3/4 ×4" uprights with 1 1/2 pins. what would you think my max ton would be? I'm thinking I should have gone with 10" × 1/2 C channel instead . But I already have the steel.
No I can't because they started fading out information like that, its not in my 26 Edition either.

im looking to nake a 200 ton H frame press that will roll on a table.i have the cylinder 9.5 od with 2.750" of threads. can you tell me what kind of steel i should use for this to screw into?
[.....IMHO: You might consider taping some pieces of roll paper, (transparent/drafting/drawing tracing paper over the window panes, to help diffuse the bright sunlight, and give you a tad better "privacy".]
Pressure = Force (produced by the ram) / Area (of cylinder), hence Force = Pressure * Area ... just play around the values to get the appropriate sizing.
Love the press Keith. You did a great job. Love the back story as well. Im planning on fixing up mine pretty soon. I have a Dake 50 ton manual press, but built a larger frame then what it came with.
