Trying to make use of a 50 ton bottle jack...
What I really need is a 30, or preferably a 50 ton press. I broke the
last 30 ton unit I borrowed so I presume 50 ton or more is needed for my process. ....I have a 50 ton bottle jack, but can't imagine anything I can wedge it and my parts between to actually use it as a press and I don't want to go out and buy lots of steel to make a press. I figured maybe between two large oak trees cut to have "flats" in them to accept the set-up. My whole set-up is around 30-35" long... Railroad tracks will move. Large vehicles will be lifted as would the average bridge - plus I don't want to be seen as a roadway terrorist. Thoughts, ideas, etc? -- Until you wake up, I will fight for you...

Lots of H press designs around. It's going to be hefty to use that jack. Pete Keillor |

Oaks aren't all that immobile under a few thousand pounds of force, and they have a nasty tendency to drop widowmakers if something straining them fails and lets them whip. 500 Lbs applied 50 feet up with a cable bends them considerably. A few I've done that to have unexpectedly snapped from hidden rot in the base. One had been leaning over my house. Luckily I was pulling on the 80' tree with a 100' rope. A few months ago I broke a 3/8" chain when an an ~18" oak trunk I was pulling down bent over a high spot on the ground and rebounded sideways. -jsw |

Plus a big press can handle the same jobs as the smaller ones. As a bonus you could make a brake for it to bend your own brackets and mounts. -- Steve W. |

See what the force it takes to punch a hole in a xx inch thick bar of steel. Book work. Solves the problem. Pressing on and off axles - press has height and width. Nice. Martin |
