[TheForge] Krause/Nazel type air hammer

Mon Dec 2 12:45:01 2002

Steve, I don't know about yardsticks, but I don't think that one
can compare Kinyons & Nazels. It's like apples & oranges.
I would love to have a Nazel,,,, and if I could find one in
working order for $1,000 I would grab it. I guess that the bottom
line here is that we are talking about folks building their own air hammers.
The Nazel is not a homemade hammer, the Krause & Kinyon are.
Kinyon = (no machining necessary) (you need a compressor)
Krause = (advanced machining skills required) (you need a lathe etc.)
Now if Krause would offer the plans AND sell "the valve", I'll bet that
he would have a lot of business. I know that I would seriously consider
using that system on my big hammer, but I don't have any machining
skills and I don't have a lathe.  I still haven't found out if there are
published plans available. Where? how much?
