[GreenKeys] 33 Print Hammers

[Jack]

Roy, et al,

The 28 typing unit type hammers occasionally "chip". If you look very
closely at the type hammer (the small tip is the actual hammer) it should
have a nice flat surface with which to hit the type pallets in the typebox.
If that hammer has some metal missing it can hit the type pallets off center
and cause mis-aligned typing and possibly damage to the type pallets in the
typebox. If the hammer looks good, then it will probably last a long time.
That's why Don and I have some many spares...they rarely break and, given
the the fact that most of us Greenkeyers aren't running the machines at 100
WPM, 24 hours a day 7 days a week, the machines will no doubt outlast us
all. In the "old days" the 28's in commercial service took a real beating
and those hammers did fracture. There was an upgrade that made the hammer
and its related spring a one-piece assembly; previous to that, the hammer
and spring were separate pieces.
The palstic/rubber hammers in the 28 reperfs is another story.
Unfortunately, they were also not made to last forever like the 33 type
hammer. And, they are a ^%$#@! to replace.
