Someone must have a hydraulic setup to install in the vise.

you are not familiar with the track record of halfway built projects in this forum?21 pages, not a single vise shown crushing stuff. WTF is wrong with you slackers

Good Morning!
One of these (with a big enough tube) could work: 2x13.125x1 DA Hydraulic Cylinder Green | Double Acting Hydraulic Cylinders | Hydraulic Cylinders | Hydraulics | www.surpluscenter.com
With a pressure supply and a pair of SAE-JIC 90s would give you ~6000# of clamping force.
A $60 harbor freight 10k psi pull back ram would work as well (the hooks are threaded), would just need a street elbow and to make it fit inside the inner tube: 5 ton Pull-Back Ram

Not nearly enough force. His youtube video brings the vise up to 40,552 lbs. We would have a ways to go with those hydraulic cylinders

He can go that far yes, but how much are you actually using daily versus seeing how tight you can make it go?
If you go to 25:50 in that video he is bending the handle on the vise using a 4-ft pipe on it and he's getting about 10,000 lb or 5 tons, that would be about what the harbor freight one can make at 10,000 PSI.
If you need more than that, talk somebody into cutting you parts scaled up to a 4x4 inner tube and put this one in: 3(76mm)x7.5(190mm)x0.93(24mm) DA Hydraulic Cylinder | Double Acting Hydraulic Cylinders | Hydraulic Cylinders | Hydraulics | www.surpluscenter.com
3 inch bore, 0.93 inch rod, rated for 2500 PSI, at rated pressure it will give you 15,973 pounds of clamping force.

I am all too familiaryou are not familiar with the track record of halfway built projects in this forum?
I look forward to seeing one of these vises squish a bowling ball for my Christmas present

I think I just threw away the bowling ball that split out of nowhere sitting in my closet. Fucking thing went off like a gunshot in the middle of the night, it was time for new sheets anyway.

you storing the vise parts in that closet?I think I just threw away the bowling ball that split out of nowhere sitting in my closet. Fucking thing went off like a gunshot in the middle of the night, it was time for new sheets anyway.

What a man gets up to with a bowling ball and a bench vise in his own home is nobody's business but his.you storing the vise parts in that closet?
In my head it was relevant, If I still had the pieces of the bowling ball I could crush them in my vise.

Well i have at least started on the mock up and cleaning up the dross. Possible i get it glued together this week.
Is it huge? Yes, its fucking massive

I also went 6tpi ACME, will be much faster than 10, and still capable of more than enough clamping pressure.

So how I put them together.

1 nut welded into tube
2 tube welded square to back plate.
3 weld front bearing retainer into moving jaw.
4 assemble threaded rod into front bearing bolt front bearing onto the moving jaw
5 screw it all the way together tack back plate to fixed jaw.
6 open and close it all the way to ensure nut is parallel to screw.
7 screw it all the way closed and finished welding back plate
8 then tack jaw sides and jaw retainers on using the screw to make sure they are tight when closed.
9. Finish weld the jaws

Got dicked with the lastest set of tubes. Damn things must have gotten bent up a little tight. Got three sets of tube stuck together .
I’m gonna have to bulid a hydraulic cylinder to broach/ expand the tube if necessary. Fuck lol

It will be close. I forget what length I cut them too. Don’t quote me but off memory it’s like 22-23” long for the threaded rod

I bought 3 lengths, figuring something like that would happen.

looks good. I left the dross and deburring for you guys to do. This is a diy project don’t you know

I can't waitlooks good. I left the dross and deburring for you guys to do. This is a diy project don’t you know
I found some decent tech that basically confirmed the extra force from a finer thread is really only theoretical and you'll lose most of the advantage to friction in an application like this.....so 6 will be much, much faster and you won't lose any notable clamping force.

Your stuff is in process. I to figure out wtf is going on with this batch of tubing. I apologize for taking so long.I can't wait
I did get another 10 sets of jaw die retainers done, and 20 front bearing blocks cut and squared up. I need to get a cnc mill to blast this shit out. Then I could make some nicer handles. I’m not happy with those.
Dont worry about machining the Bearing block for me. Just throw it in the box. I may adapt if for some 1.5in -6 threaded rod I have on hand from my dinning room table build. We really should have just shipped all that here for machining. USPS might kill you.Your stuff is in process. I to figure out wtf is going on with this batch of tubing. I apologize for taking so long.

If you want, ship it over and I can knock it out then ship it back. Might be a week or 2. I have a job loaded on the cnc but I should be able to mount them on the other side of table.Lol I should. I’ll get this batch I’m now a master Bridgeport production guy. Especially when the tolerances are a little forgiving.
The nuts for the 1.5in thread I have on hand have a flat width of 2inches but I can turn the whole nut down to 1.875 with plenty of meat left. Also have some 1.75ODx.120 DOM tubing in the back yard for the rear tube to weld the nut on. Cant make this too easy on myself.

So how much am I going to regret going with regular threaded rod (1"-8tpi) I bought the shit before everyone started this "lets do low thread pitch ACME"
Fuckers
I know i will never come close to wearing mine out because I dont run 1/10th the operation ThePanzerFuhrer does

Thanks for the comforting words
. I think about 18 pages ago you said you built your current one with the1" 8tpi and i thought, good enough for that dude to abuse, good enough for me The bit im not looking forward to is plug welding the nuts into the bar.
