I just had a "mistake". I have NO idea what I did wrong.

I just an hour ago finished assembling a 30-T dual-cylinder press for a
customer, and it's heavy -- about 1400lb, including the two 6" hydraulic
cylinders; one 12" stroke, the other 8", and the fat 100lb boss plates on
the cylinder rods.

I had built in some alignment capabilities for about an 1/8" lateral
movement of the cylinders, front/back, and side-to-side, and also some
tuning screws to allow shims to be fit under the reaction plates to cure
axial misalignments.

I got it all plumbed yesterday, and SURPRISE! No leaks, drips, or even
any damp spots -- and it's _all_ hard-piped, which I hate to do.

But today, I mounted the pressing mold on it to check the alignment, and
to start the fairly slow process of getting it all trued up.

DAMN! It was dead-on within 5-thou all the way around; as-welded and
bolted-up. DAMN! I just picked up a whole DAY of schedule! (which I
probably wasted getting it that true on the first pass. G)
