I would like to use this cylinder:
http://www.surpluscenter.com/item.as...name=hydraulic
for an operation similar to an "H" frame arbor press. I bought a Northern
Equip. 20 to press for the basic. The top has a 5/8" thick plate welded to
a 1/8" x 6" x 2-1/2" "C" channel. I want to mount the nose of the cylinder
into the plate so the body of the cylinder is above the press with the rod
pointing down. One thought I had was to hole saw the plate/channel, weld a
steel donut onto the cylinder and insert the cylinder into the sawn hole and
make a split clamppy kind of thing clamped above the channel on the
cylinder. Can I safely weld something to the cylinder if I promise to
stitch it and cool it in stages? The cylinder will need to only put-out
1,000 lbs or less. Maybe I could get away with split collars on both sides?
How much pressure would they take before the cylinder pushed out? Thanks
for your synapses!




I like the split clamp idea. Buy a split shaft collar from
McMaster ($12 for a 2-1/4", for example) and drill a few
holes in it to fasten it to the top plate of the press.
Ruland says it'll slip at an axial load of 8000# on a soft
shaft if you torque the clamp screw to 325 in-lbs.

Avoid clamping on the tube anyplace the piston passes.

Welding near the nose would probably be OK if you
disassemble the cylinder first.
