So Monday I go to this farm auction. I see this control and wait 5 hours in the hot sun till they sell it. And of course, it was on the last wagon load they sold. I got it for $7.50 and thought I was on my way to building a hyd. press. I was pretty stoked, until my dad said it was not a spliter control and that it was for a tractor. :( He!!, what do I know? It looked like the control on his log spliter.
So anyway, can I make it work? I could get different fittings and probably sell the quick change dealies and hoses?

Now I must whine some. I feel like such an idiot and wonder if I have what it takes. I mean, I am 34 years old and just feel like I should know this stuff. Like earlier this summer when I bought the huge one way hyd. cyl's thinking they would work. I only paid a dollar, money is not the point. My lack of knowledge is. I am just about sick of asking stupid questions on stuff I should know by now. I feel like a fish out of water. I can do it, I have tons of patience. I just wish I knew more than I do about some things. I am slowly learning though and I owe it all to you guys that put up with my stupidity. :)
 
Hey, I think that'll work, as long as the handle moves up and down but returns to center every time (I know there's a term for that but it's 2 am and I don't feel likw looking it up).

My control valve has 4 ports, though, not 6. Don't know what they are all for on yours.
 
There is no center, that I can tell anyway. Only in and out. Short stroke at that. Now that you said yours returns to center, I am having doubts. :(
Thank you for the reply. :)
 
Hey Junk... Don't beat yourself up, bro. Some guys learn thsi stuff from osmosis, like breathing the air. Others have to beat it into their brains before it begins to make sense. What is your job in real life? What has your primary interests been? If neither of these can be answered with anything but something in the mechanical arts then don't feel bad. I was an aircraft mechanic for 15 years, and an industrial machinery mechanic/machinist for 10 more. I still don't know everything, and I study catalogs like Grainger, McMaster-Carr, and MSC like there is no tomorrow.

You got the desire. You got the fire. Now go make something cool out of it! =)

Don't sweat it, that's what this place is here for. Without questions, there would be no need for it.

Like JHiggins said, everyone didn't have the good fortune to work around this stuff all their lives, Hell, I worked in an office, or behind a counter most of my life.
But again, like JH said, read all you can, and ask all the questions you want. You'll get there. :D
 
If you ever get to the point you don't have to ask questions, then I'd sure like to meet ya, cuz I am always in need of a couple answers, and I've never met anyone who has all of em, though Mike Hull comes closest cuz he probably has a link to it somewhere.....:D

A couple points on the hyd. control: the one I have has only 4 ports, but if that is for two separate take-offs, one pair could probably be plugged off.

When building a press, it is good to have a neutral detent position, with a return spring, so the press just stops when you take yer hand/foot off the actuator. That way you can use it like a vise to hold cable to twist like no other vise ever did..

The preferable control for a press will have an adjustable relief pressure, so you can get the most out of your hydraulic system. Not all models have that.

Why do I know these things? Because I bought the wrong one the first time around and had to ask some questions.... :)
 
You might be able to make it work.
The tractor controls I have seen are for a one way pump that runs off the engine, and are either 2 way or 4 way. 2 way would work a normal cylinder like you would lift a plow with, or raise a dump bed on a wagon or truck. The 4 way controls sometimes have 2 handles or only one that moves in 4 directions. You use them for front end loaders (raise, lower, tip up, tip down)

The lever on yours appears to only move in one direction. I'm guessing that its a 2 way, and that the multiple ports are so you can control multiple cylinders on one lever (like you would need to lift something big like a 6 bottom plow up)
If the lever doesn't have a neutral/center, its probably designed for a lift. It stops wherever the lever stops, you want to raise the equipment higher you raise the lever higher, and vice versa.

If I were you, I would go ahead and get the type of cylinders I knew I needed (if you don't already have them) and hook it all up on the floor, you'll need the lines and fittings regardless of the control. If you can control the cylinders the way you want then your set.

As far as one way cylinders, I think you could make those work too. Those are meant for applications where gravity will bring the stuff back down when you let the pressure off. I don't know much about forging presses, but from the pictures I've seen you have a die/plate on the cylinder and an anvil/plate that the cylinders pushes down on top of. For a one way clyinder you would just have to make it upside down. Have the stationary plate on top. Might be kind of clumsy have the plate your laying your billet on moving, but I bet you could make it work.

As far as the quick hook ups and stuff, I'd keep those handy. They mount on the threaded end of the line with teflon tape or TFE paste just like other fittings. The nice thing about them is that while they may leak a little bit (not under pressure, provided they work right), they won't let any fluid through the lines your not using.

I'm pretty sure you onlt have 4 ports there too. 2 of them will be your input and output to the pump. Not sure which ones they are, though. That looks like something somebody had set up special to take on and off of whatever they were running it. They might have plugged the 2 quick attach lines, into existing sockets on the tractor and then plugged lines from equipment into the 4 sockets on the control.
