I feel rejected. No one knows why I want to use it horizontally?
Various reasons and situations to use it upside down. BIG difference
between the area of the base and that of the top of the piston. And
sometimes you just can't move what's there, so the big end HAS to go up.
Besides, if Ernie says he can do it, I'll put my buck on Ernie.
You want to use it upside-down in a hydraulic press, so you can thread the
top in and out. Makes much more sense than welding a piston to the bottom
of an H-arm and pushing that whole arm down.
You have to figure out which hole in the base (this is on the inside) is
the fluid intake. Then you tap that hole for a piece of hydraulic tubing
which sticks way to the other end of the reservoir. Then it sucks it up
through the hydraulic tube just like soda through a straw. That's how.
The guy who bet on Ernie wins. As usual.
If you're using it for a press, you spend the extra few $ and get the
chinese port-a-power type hand pump and cylinder and mount the pump at
the side of the press along with a pressure gauge, just like a good
To widen the space between two pilasters that have settled, making the
wrought iron gate bind. When I have the two pilasters separated to the
proper width, I will put in a decorative horizontal to keep them apart.
If you haven't figured it out yet, horizontal should require no
mods, just place it pump side down and go. Pump down should make the
little rubber fluid fill plug on the side of the main barrel point up.
Totally upside down, yeah, I'd just use a Porta-Power cylinder with
a separate pump. No sense spending $1000 of your time modifying a $25
I also use screw jacks in conjunction with bottle jacks to raise things.
I'll use them this year to replace the square posts on my cabin porch with
real tree trunks. They're trick to raise something an inch so you can
change a post, or hold up the entire porch while replacing supports. And
just plain mechanical advantage of the screw head of a concrete form support
to widen openings. Hydraulics is just infinitely easier.
Yall dont be forgetting the current version automotive scissor jacks.
They sit low, can have a wide jacking range and are damned cheap at
the pick a part. Some even have lifting hooks already built into them
And you can spin them up and down with a pretty plain jane drill
motor, and they work in any position.
Ive got bottle jacks from 1-50 tons
Ive got PortaPowers from 2-15 tons
I use the range of scissor jacks Ive modified more than anything else.
With a bit of enginuity , you can modify them to push, pull, lift
I use them on the welding bench a LOT.
And the best and fastest way to get through a chain link fence is
still the old fashion bumper jack.
Ive even used bumper and scissor jacks to straighten axles.
You can pick up a pretty good assortment of them from wrecking yards
for a few dollars each
