[TheForge] Side-loading question (was: 15Ton Press)

Fri Jan 18 12:54:14 2002

Dave,
While you're asking, find out whether there's any play in the joints =
between cylinders and the frame (on one end) and the ram (on the other).  =
Think "ball and socket joint but with very little motion".  My point is =
that such a connection with three or more cylinders plumbed in parallel =
should prevent side-loading of the cylinders.

My friend Joe Baer (you UMBA and some of you BAM guys know him) has a=20
4-poster hydraulic press.  Put anything of any shape at forging temperature=
=20
between the platens and ... squish, you have a flat something.  400ton =
will=20
do that.  It's a monster press.  This is not a home made press.

It is single pump and I believe that all four rams are connected in=20
parallel.  I'll have to ask.
