Thank you - great idea - I tried it.

Unfortunately, there's a 56lb difference between the two with about 600 lbs of force in the vise. It's a light weight vise and that the max I could put on...

Your description of the parts involved is more accurate than mine.

Both have similar sealing parts. Both appear to have O rings based on very close inspection and moving the O ring around etc. ...

Also, it might be difficult to get the air out of the tripod system. A pump might be needed.

The pump idea is great but there's only 7/16" travel with the ram I have so I don't know if that could work. You can get rams with greater range of travel.

Your flat piece of steel idea would work. The groove on top of the piston would allow it.

The drive on idea is pretty cool.

I just used a scrap piece of 1/2 ply at first. It was probably 6"x8" but, by about the second weighing it was bending pretty bad and starting to crack. I...

The 20psi gauge graduation on the 1500psi gauge would be better than the 50psi on my current gauge.

4247

You'd easily be able to see 800psi or 820psi for example but also would be able to...

So far I've found that you can get 20 psi increments on (up to) a 1500 psi analog gauge. The max weight measured using the 10 ton ram with that gauge would be 3375 lbs. That's good enough for my...

No problems with spinning at all. The parking brake was on, transmission in park, another wheel chocked front & rear just in case. Garage floor is level.

Anything less than 3/4" ply would likely...

I'll try the blocks for sure. It wouldn't be too surprising (as Booster pointed out) to see that 100lbs (5%) over, or some of it, being caused by lifting one end of a sway bar almost three inches. ...

Good point about the front wheel possible spinning - would have to be prepared for and prevent that.

I might get one of those someday. It would be useful for the Travel Trailer also.
