Converted 65 Year Old Shear to Hydraulic

[@RobertEskinner]

Looks like the conversion is successful . Thanks for the video.

[@craigsmachineshop2040]

Thanks, it just got a hydraulic pump upgrade which I covered in the latest video.

[@hippie-io7225]

Your projects are practical and well done. You use that small space of yours very effectively.

[@TheCNCDen]

Nice to see you still have the paper towel holder and it still looks shiny.

[@VastCNC]

Looks like a lot of interesting new developments, and content coming. Thanks for sharing. Looking forward to following along the evolution of your shop.

[@craigsmachineshop2040]

Thanks! Yeah, it’s been a busy 3 months. Time to catch up on my videos.

[@GregsGarage]

I like that stomp shear! I missed out on one from a building we are renovating... I am going to go back and see if I can chase it down. I've wanted one since high school. I'm looking forward to the punch press 1000.

[@craigsmachineshop2040]

Hey Greg! Cool, yeah its a great addition to a shop. If you get it and want to convert it, let me know if you have any questions. Yeah, looking forward to making the video on the punch press. I went all in on the details with it.

[@stanmcdonald]

what is the bore and stroke of the cylinders your using? What is the specs on the pump pressure and gpm? I have a shear id like to do like you did.

[@javie3828]

Just saw your video about the hydraulic shear. What size of tie rod cylinder did you use or stoke size.

[@RobertEskinner]

Did you install a flow divider in your system? Thanks.

[@DFEUERMAN]

Well done! Love your videos! I had a similar hydraulic DIY project and also selected a Majister cylinder and same kind of 12vdc pump due to attractive price and tremendous pressure, but also had a power supply issue. I used a harbor freight ~$120 jump starter that says can do 200amps at 12v. I purchased the older model with a big bridge rectifier rather than the newer transistor type. It burned out and I diagnosed the diodes failed after a year of use, but found cheap ebay "button diode" replacements for about $5, the original diodes I think were only rated for 35amps so I replaced them with something like 70amp diodes, and now it runs at about 100amp burst (I think repairing the transistor version might be more difficult to troubleshoot, or it might run flawlessly, as is...)

[@craigsmachineshop2040]

Thanks! Not really familiar with the electronic stuff. Glad you got it fixed.

[@manuelchacon4593]

Have you tried a power supply from 120v to12v to eliminate the battery that’s what I’m using for my wench in my shop

[@humblyright]

Nice job, well engineered. Do the hydraulics allow you to cut thicker gauge sheets then the manufacturer maximum (guessing 16g) as a stomp shear?

[@craigsmachineshop2040]

Thanks! I tried 1/8" aluminum once and one of the hinge pins sheared off. I replaced it with an alloy steel one. I haven't tried that since. I cut 2 of 16 gauge steel by accident, the scrap from the last sheet was still in there. It twisted the rear connecting tube (2" steel pipe). One cylinder is now about 3/4" out of line with the other. It still works fine though. lol.

You are amazing for sure! I can't wait for you to post a video on your newest punch press. It appears you have some stops set up for controlling how far the ram will travel - I'm assuming that's for your custom Unipunch countersinking process? I've just purchased a Redline 50 ton electric over hydraulic press - it uses the same motor/hydraulics you have purchased. I would love to set up a foot pedal to control the up/down ram rather than the lever. Any thoughts on how I can do that? I'd also like to move the oil filled pressure gauge up onto my press rather than on the pump where it is now located. I remember you mentioned you were thinking about doing that on your first press where you had purchased a different gauge (50 ton gauge rather than the 100 ton gauge they sent with your motor/pump). Craig - can we see some of these in a new video? You are the master and I the humble student wishing to learn more from you! Thanks, mikey

[@craigsmachineshop2040]

Wow, thanks Mikey! Funny, I was thinking about starting videos again the other day. Yeah, I was thinking about converting my 50-ton to electric controls but haven't had the time to figure it out. I know it's a matter of adding selenoids to the pump but I'm not sure if they are available for this pump. I got another pump from Vevor for another project that is electrically controlled so I might try hooking that up to see if it has enough flow rate to work. Yeah, the Unipunch countersunk punches work great with limit switches. We just finished a job of 180 covers in 10 gauge and the punching was really fast. I changed the gauge to 50 tons but just left it on the pump. You normally just get a feel for the tonnage by the sound.

Great video, always interesting-looking forward to your next installment-well done✅👍

[@craigsmachineshop2040]

Thanks 👍

[@FISHBREATHH]

I have a 3 ft 16ga stomp shear and you are correct its not much fun. well done. thank you for the video

[@craigsmachineshop2040]

Good to know it is just me. lol Thanks!

[@boboshop55]

Hey! Great solution here. I didn't catch the maker or supplier for the Hydraulic unit?? I'm going to give this a go. -K

[@craigsmachineshop2040]

Thanks! Magisterhyd.com

[@duramaxmak]

Craig did you ever consider a hydraulic unit off of a car hoist. I own two flex arm tapping arms they are game changer for tapping holes

[@craigsmachineshop2040]

Yeah, I looked at them but couldn't fine the correct combination of PSI, GPM and price in 120 V. Did you get the Name brand Flex Arm? I looked into the electric version and it was around $6K. I may end up changing to electric because the pneumatic is so loud. I may end up going with an import though to be able to afford it.

[@machinetools431]

Make a video on the automatic punch press asap! Very cool

[@craigsmachineshop2040]

Thanks! I'll do my best.

[@stanmcdonald]

From what I could find most 12 volt power packs put out .68 gpm

[@theoguy5321]

What ton are the cylinders

[@craigsmachineshop2040]

They don't actually rate them by tons. It's a 1.5" bore rated at a max of 3000 psi.

[@bradcline2582]

@@craigsmachineshop2040 What is the cylinder length. Thanks

[@craigsmachineshop2040]

@@bradcline2582 I think its a 4" stroke

[@khairulanwar5189]

How many mm thickness

[@craigsmachineshop2040]

16 gauge

[@C33Chevy]

How far does the back gauge go

[@funone8716]

You're clever but I think you over think solutions to problems. I would have put the money you spent on the shear toward a cnc plasma cutter. It would cut those pieces out super fast, with much less fiddling.Plus it can cut all shapes of holes and contours........no die set needed.

[@FISHBREATHH]

show us your cnc set up,

[@funone8716]

@@FISHBREATHH I'll show you the door....don't let it hit you in your ass.

[@craigsmachineshop2040]

Thanks. I looked into getting one a while back but I just don't see I have the space for it and doesn't seam appropriate living in the suburbs, especially considering how much galvanized I will be using. I had a local shop plasma cut some for me once and had major rust issues. Half of our stock is unfinished. I would have to clean and re-oil all the covers or deal with rust inhibitors when I am trying to keep the amount of chemicals to a minimum. There are many other considerations but I won't go into details.
