[TheForge] 15Ton Press

[Ralph Sproul]

        The porting from the cartridge to the cylinder chamber was 3/16 so
there was no way I could get the press to travel with that size port
(venturi), so I bored a hole in the end of the cylinder and welded in a pipe
coupling and solved one of the problems.  The other line also went thru the
cast housing on the end, so I bored it out to 1/2" from 1/4 as that was
possible.  The first one could not be done unless I cut the cylinder apart
and then did the machine work, and then rewelded it.  So I had two days into
making a $20 cylinder work and I should have just gone and bought a new
cylinder and been done with it...........or waited until I found a regular
loader arm cylinder that would have fit the task.
