Tim, very nifty stuff. But is this perhaps better done on a table
saw? Or maybe a modified deli slicer? Or a band saw with an
extremely tight, wide blade. I would think you will get the best
results with a spindle that is supported on both sides of the saw.

You might be able to get upgrade bearings for the bport (ceramic
balls/races) which could handle high speed running.
