(1) A "broken bit" cutting tool system that can save hundreds of dollars in tool expense.
Even though the included pictures show only round bits, the bits can be ground into
conventional cutting tool shapes.
(2) An accurate homemade lathe chuck.
(3) A very old but accurate way of cutting threads. The MultiMachine Yahoo newsgroup
will have plans for a CNC lead screw when one becomes available.
