View Full Version : Turn 20t bottle upside down?
11-10-2007, 03:40 PM
I have built myself a Texas size home garage press out of junk iron and bought a cheap ass 20 ton bottle jack. I would like to turn the jack upside down with a resevoir on top of the press. I don't know where to drill the holes in the jack. Has anyone done this or seen it done? OLDBEAR

I don't know. I did find this site with a little info., it probably won't help.

I might be wrong but I don't think a bottle jack will operate properly upside down?

I tried to use one side ways once and it would not work. They are not all made the same obviously since there are power pushers & other tools where the jack are sideways. Upside down?
Sounds like youv'e seen plans someplace ?
I thought " Texas Size" would be more like 50 tons or so!:eek:

The cylinder can be any position you want, the resovior is another thing. I'm pretty certain if you attach a line to the drain/fill plug hole you could hang anything that holds oil up above and it'll work fine. It's all about not pumping air into the cylinder. Even a cheapo will have wipers and o-rings galore, you just gotta have nothing but oil on the pump piston.

I found this picture of bottle jack turned upside down. I have a Harbor Freight 20 ton. I am wondering how deep that hole in the base is? Anyone want to try it on there jack first? OLDBEAR.

Or could it be, that line at the base is screwed into the check valve hole? Or am I missing something? OLDBEAR.

I'll agree it looks like they're using the check valve hole in the bottom and the fill hole in the side for their connections. Can't tell from a B/W photo, but I hope they used steel brake line tubing and not copper for the fluid lines.
