The part I need thoughts on are how to pre-load the carbides in such a

Tom, this might be a crazy idea, but I wonder if it'd be too complicated
to incorporate a mechanism to rotate the cutter 90 degrees on each return
stroke, thereby presenting a "new" cutting edge to the work on each
cutting
stroke. This would make the cutter last 4 times as long between changes,
requiring the cutter only to be flipped over when dulled. I'm imagining
some
sort of a ratchet/indexing mechanism.


Good thinking but it would be difficult to get the rigidity. I'd be happy
to just flip the carbides once a week in 5 minutes or so.
