    You could do what I did with some scrap cast iron, once, Y.O.D.

    Nobody wanted it, it was heavy, and useless for anything but a paperweight.

    So....I put it into a close fitting cardboard box, and gift wrapped it, complete with a bow. I left it in the back of my pickup, and within two days, somebody stole it....BTW, that was when I still lived in Los Angeles....

    People often complain about fastener quality on cheap imports.

    I've got their 20ton press and thougt it was a bargain. I was unaware of the plate breaking problem so will likely scrap mine unless someone wants to pay shipping for some fine chinese cast iron to make a cake plate, drink coaster or maybe just to hold down the old picnic table cloth I do as a matter of course wrap anything in the press in some carpet strips before putting the arse to it.

    I've had my 12 ton for over 25 years, wasn't from Harbor Freight but may be the same item.

    Mine is a floor press and it suits my 6ft 2 body just fine.

    I wanted the 20 ton but didn't want to try to wrestle a 200 lb weldment into basement. Too bad because it would have only been about $60 extra. It was only a little over $100 for the 12 ton.

    I think I'll get four top quality 10.9 bolts for overkill. Very cheap insurance.

    I've used the heck out of my 12 ton plates and also have a pair of the 20 ton plates - never an issue with them. I've had the jack into overload only a couple of times. No bending or other issues.

    As for getting axle bearings off, I've found it much easier to score and snap off the outer race, remove the balls and cage, then score and snap the inner race - rather than use the press.

    As they come from the store the 12 and 20 ton presses that I've looked at are too short for the floor and way too high for the bench.
    Here is my version of getting the press to a comfortable height.



    I used 1 3/4" pipe with a round circle of steel welded at the top. With a nut welded to the the bottom side of the plug so that you end up with a weld in threaded insert that bolts to the bottom of the press frame.
    Weld on some feet and some cross bracing for stability.

    this pic is of it upside down ...the ends of the uprights have to be shortened to stop it rocking ..other than that ok .

    Recently bought a HF 12 ton press. Needed it to do some rear end bearings on a car I was working on. Unfortunately, I didn't put it together myself (floor model) and was dismayed to see the press cross pieces and the press plates bend at an alarming rate. The spindle under the hydraulic jack is bent to one side, and the guide rods were soon binding.

    "Well, this can't be right." I figured, the jack wasn't exhibiting any undue amount of pressure, but everything was getting scary. I wondered if Chinese steel "U" channels were actually weaker than American made ones...

    After almost pulling the press over onto myself, I realized all of the bolts holding it together were just finger tight...That's what I get for assuming "professional assembly". I got out my 1/2" drive Ingersol-Rand impact wrench and went over all of the bolts backing every one up with a wrench. Every one of them were loose. As I tightened the bolts, I carefully aligned all of the beams and cross-pieces. On the next attempt, the press performed perfectly....I may decide, later on, to weld some of the structure in order to get even more rigidity. First things first. I need to make a new press "snout" that holds the press piece onto the bottom of the jack, first. The one on there is bent off to one side. Then I can machine a new ram for it.
    I realize I probably should have bought the bigger press(20ton) and wouldn't have had this problem, but fortunately, I can make this one work...it's just going to take some ingenuity.

    I've not had that problem at all. I've done car wheel bearings and other similar tasks with no bending. If you're not happy with the 12 ton and it bends, I'd sure take it back and show them. They'll probably give you a credit against the 20 ton job.

    The plates that came with my HF 12 ton have various V and half round cuts in the edges. I figured the plates are to be used on edge and work is held in the cuts and force is applied in the middle of a part to bend but the plate edges are *wildly* out of square.

    Could it be safe to use to the two plates in a stack?

    I priced flat bar and plate from online suppliers and a small quantity
    to make two plates starts getting around what the press cost!

    Can you clarify on this? I have been thinking of buying one of these but have no idea what a wire bail is.




    I had the valve the other way and it would hang up and only would allow the valve to open part way. Was just easier to flip it and pop the bail.
