Yes there are parts that can't be made by hand. Yes hobby work
does require parts that are exactly alike - 2 to 50, perhaps -
depending on the project.

The other thing is that people do like to have a hobby and the
end use of the object produced is simply to have that object work
as planned for the sheer joy of it. A working CNC machine is
valued for its own sake, not because it can be used for anything.

This is a common American affliction. By the time developements
actually get into the mainstream of American manufacturing
processes, they have already been invented and used extensively
in private by very intelligent people who find it inhibiting to
work for anyone except themselves and for their own enjoyment.

Technological advancement has to start somewhere and this e-mail
list contains people who are on the foreskin of machining
ingenuity.
