Speaking of casters. In my ongoing quest to put almost everything on wheels,
the 20ton floor standing H press is the next likely target. It is an awkward
beast to muscle around when I need to reconfigure the shop. It has angle
iron sticking out each side for legs (like most commercial built H presses).
Any reason I couldn't put a 4" caster on each corner?
It would of course make it easier to move around, but I wonder how the
casters would affect it when in actual use? Seems like the usual forces for
an H press are pretty much contained within the structure on a pretty much
vertical basis, unless you are really reefing on the jack handle I
suppose... in which case you are probably not using the right tool for the
Anybody have their H press on casters? Does it work ok?
Along with all of the other answers, I'd add that I'd "recess" the
casters, i.e., mount them on sort of an L-bracket, so that you only have
to raise the base of the press maybe 1/4" - 1/2", rather than 4 or 5
________ BASE _________

(or coat the floor with something hard, polish it, and put the press
on a big air bearing. ;-) )
Rich, you clearly don't have to deal with a space-limited shop. The above design
is great for stability but it really burns floor area. I wish my press were
smaller, but it's the size it is, and I don't want it *any* bigger.

I can sympathize with that completely. Why not put two fixed casters on
one side mounted so that when it tilts slightly it's supported by the two
wheels? Put a pad or lift point on the opposing side and you can then use a
floor jack or other means to lift that end to move it about.
I have also done a contrivance with casters mounted on a plate attached
to hinges, and an external lever, where you lift the whole thing up by
stepping on a lever, rocking the plate level and lifting it up onto casters
for easy movement. When where you want it to be, lift the levers (sometimes
easier said than done!) to let the device drop back down onto its base.
Depending on how much you move it and the floor condition, you may want to
lock the mechanism in the mobile position, since if I catch something going
the wrong direction on the one I did, the plate and casters would sometimes
pop back into the stowed position.
I had a hard time visualizing this the first time I did it, but take a
long plate and mount it on sturdy hinges, long ways. To the plate end,
attach a lever perpendicular to the plate such that it extends on the
_other_ side of the hinges. Mount swivel casters to each end of the plate.
My item had a flat bottom, and when the plate and lever is "up" the casters
support the plate which then sit flat on the bottom. The distances and
caster size have to be worked out with a bit of simple math so that the
casters will just rest on the floor in the stowed position but raise the
thing when rolled up. Step on the lever, which causes the plate to flatten
out on the bottom and the caster's usable height will lift the item up.
Does this make sense? I wound up using this so since the item (actually a
bingo machine console which spends most of the time in storage) had a
"skirt" to keep stuff out and look immobile, but be easy to move by folks
other than me. The levers stuck out arc shaped slots on the backside.
I wrote an article that included wheels on a press. I posted some
of the details in the dropbox.

On the list, a fellow asked about putting wheels under his
20 ton press. I posted this to share what I did.
This is the dolly Wheel details that is part of the Home
Shop Machinist article I wrote "Build a 50/30 Ton H-Frame
Hydraulic Floor Press". The article is in the May/June
2004 issue. These are detachable and I pull them
off when not moving the press around.

Each wheel is on a pipe that serves as a lever, so there are
4 wheel units. 2 have casters and 2 are not. To engage the
wheels, do one side at a time. Attach the wheel unit, one
solid and one caster. The pipes will be about a 45 degree
angle. Push down on both pipes and when you have them pushed
level, slide the latch that is in one pipe into the other pipe
and the press is on wheel for that side. Then do the other side.
I have a lot of weight on this press and thus have taken to
using a piece of pipe that fits between the press's jack and
the floor(vertical) slightly offset to the side that I'm
setting the wheels. Then use the press jack to lift that
side so one does not need to lever up the press with the
wheel pipes. Once you jack it up, simple slide the latch and
do the other side.
Hope that helps,
