That is excellent advice, unless you can find a source that is willing to do
the job cheaper. Creating a thread of that size by hand would be beyond
your ability. The die, alone, would have no value without a
stock-----which would cost far more than having the job done. Then you'd
be faced with holding the material so it wouldn't spin. A common bench
vise most likely would not work. An 8 pitch thread will sort the men
from the boys instantly-----even if the material is free machining. It
likely is not.
