[TheForge] Air Hammer Slides.....

Some people use roller blades in their treadle hammers i believe, to me I
think its easier to use the UHMW, although it might have more friction.

As I was building a trolley for my new swing arm crane today, I marveled at
the fact that no one uses cam follower bearings for the hammer head on a air
hammer.... As always my question is why?

They are relatively cheap, and will roll on about any surface, they could be
easily pre-loaded to remove slop, and 6 units would provide service for
life, with very little if any resistance?  They come in all sizes and
shapes, and most are complete with grease zerks.

Any insight?

A picture of the nw corner of my shop reveals the new 1000# swing arm crane
although it does not yet have the trolley affixed, nor does it have the 300#
of counter weight attached to the aft of the load beam.

Also in the picture is my new hydraulic press frame, It has a single
cylinder to be mounted on the let like a standard punch type hydraulic
press, the center will have a moving beam driver by two 3.5" hydraulic
cylinders so it can be used for shearing, and sheet metal forming as well as
die cutting work, and making forging dies.  The single cylinder will be a 7"
Diameter by 18" extend with an exertion force of about 57 tons...
Guaranteed to break the press I think.
