[TheForge] Krause/Nazel type air hammer

[theforge@mailman.qth.net]

The discussion on the Krause hammer is very interesting to me 
and I hope that it continues.  I've been gathering the steel items 
needed to make a Kinyon style hammer but have on an air cylinder 
that could be used as far as air parts are concerned.

I like the Krause hammer very much and think that Mark has done 
an outstanding job of developing the hammer.  I think that one item 
that makes some people shy away is that for sure there is 
machining involved and many don't have access to the mill and or a 
lathe to get the job done.   If I remember correctly the valve located 
between the two cylinders on the hammer was totally 
fabricated/machined by Mark.  The cylinder in the rear had grooves 
machined in the shaft to allow air to escape from the cylinder to 
help control how much air gets to the valve.  I would think that both 
these functions should be able to be solved using off-the-shelf air 
items (but this statement probably shows how little I underestand 
the problems involved).  

To my way of thinking Mark's hammer is a truly self contained air 
hammer, but I remember about a year or so ago some took great 
exception to calling his hammer self contained.  But this feature of 
supplying it's own air is what makes his hammer so neat.
