HF is selling air operated jacks so cheaply that it is hardly worth building one.

I put an HF one on my 20 ton hyd. press and it works fine. It is a bit slow compared to a hydraulic pump with electric motor, but gets the job done.

Yeah, build your air powered hydraulic pump first then we'll talk. :)

I bought a 20ton a few years ago when they were $89 plus I had a coupon to boot. You can't build one for that. The 12ton is now $89 but HF puts them on sale often.

Here's the 20ton: http://www.harborfreight.com/20-ton-air-over-hydraulic-jack-95553.html

How the hell did you know it cost me $100 for a lathe to make a 25c doorknob, you've got my shop bugged, please don't tell SWMBO, or she'll expect $95.75 change!

I picked up a enerpac air/hydro pump from the local salvage yard for $25. I plan to use it on my HF press.

I broke two air/hydraulic jacks. Went with a fast lift 20 ton jack and was happy till I got my big press done.

Back on topic,a few weeks back I bought one of these air over pumps from HF-

And then you can get off fleabay one of these which can be packed around and used for a variety of other tasks-

I put an HF one on my 20 ton hyd. press and it works fine. It is a bit slow compared to a hydraulic pump with electric motor, but gets the job done.

When you did, did you invert the jack to get it ram-downwards? If so, what needs modding, on a manual jack the pump pickup often needs extending to keep it from sucking air, is it similar with the air-over jacks?

Thanks,
