Think this couldbe hooked up to a tubing bender?

[doonjumper]

Saw this on the CL and thought I could hook it up to a bender and make it hydrolic. I's powered by a 5hp single phase motor (which is all I really want this for) but what the heck maybe ill keep it as is if I can hook it up to a bender.

Anything is possible I guess. It wouls suck to buy it, then it not work out though. Research it first to see if it will or will not work out. Draw up a plan and go from there.

I need the motor, so Im gonna buy it anyways. Guy is asking $200 for all pictured. He was gonna make it an on site log splitter. I was thinking about alternate uses. I would think all I would need is a way to mount it to the bender. If not, the log splitter is a good idea too! I need the motor for my foundry chop saw. Or I could take the motor and just try and sell the rest of the unit to someone else.

If its in good shape, its a pretty good looking deal.

Actually a log splitter is about the least useful use for it. Unless you have lots of wood close to your shop, its not going to be too convenient.
Running 2-3000 psi hydraulic lines long distances is not cheap or easy, nor is running a powerline that will run a 5 hp motor.
But, if your woodpile is close, then it might be good.

Otherwise, its a very useful setup.
You have a fairly strong pump, a good tank and a radiator for cooling. After that you just add accessories.

A hydraulic motor will run an air compressor, and/or even your chop saw.
Cylinders can be adapted to run your tubing bender, a bearing press, a metal shear or an ironworker.

With creative plumbing and valving, you basically have one 5 horse motor whose power can be applied anywhere in your shop.
Either one at a time, or multiple places if the load is not too much.

You might want to check out places like these, and order catalogs to get an idea what is available.

You lose power converting from the motor to the pump, moving the fluid and then converting back to force again.
So, with a 5 hp motor, you cannot get 5 hp worth of power remotely, but its not anywhere near as bad as trying to run a 3 phase off single phase.

This site has some conversion factors.

If you can run the chop saw with a hydraulic motor off that unit, is hard to say. If you can find out the pressure and flow rate off that pump, you can calculate what size motor would work.

The guy is an engineer at a Hospital. He said the hospital bought this about 8 years ago and used it a handful of times. He says he was the only one who used it. He said its been in storage taking up space at the hospital and they told him to "Make it disappear". Thanks for the info. I had never thought about the uses you mentioned.

Used properly, hydraulics is very useful. All a big bearing press is, is a super strong frame with a hydraulic cylinder.

The nice thing about hydraulics is that if you have to, you can trade speed for power all day long.

A certain horsepower motor will push fluid at a certain volume and a certain pressure.
If you need a ton of push, and have 1000psi available, you can use a cylinder with 2 square inches of piston area.
At full flow, it will push at a certain speed depending on the pump's output.

If you need 10 tons, and don't want to buy a bigger motor and pump, just go with a cylinder with 20 square inches of area.
It will only move 1/10 as fast, but it will move whatever you hook it to.

Look through some hydraulic catalogs, and you will get some ideas.
5hp is not a lot, but its enough to do a lot of work.

I have a surplus 10 horse powerpack mounted on a tank in my shop that a friend gave me.
He threw in a cylinder strong enough to make a 50 ton press out of, but I've never built it.
The steel costs were just too high.
One of these days, I'm going to buy a press from harbor freight and replace the cylinder.
But, if I do, I am going to put on a pressure gauge calibrated in pounds or tons of ram force combined with an adjustable bypass pressure regulator so I can control how hard it pushes.

Sometimes you just don't want 50 tons pushing on parts.........
