  You also might look into the extension cable for the Dremel motor unit;
this would take the load off the main bearings and put it on the
relatively cheap cable end.


  Obclassiccmp: In the late 70's, I bid on (and won) a Cincinnati Milacron
single-axis NC X-Y pcb drill unit, that accepted standard 8-level paper
tabe (as might be punched on a Flexowriter) and made holes in thin stuff
accordingly. It was in running shape, and still had a spool of program
tape, which, when rewound, commanded the drill to punch a pattern of holes
in whatever was on the platten. The logic of the device was all DEC
Flip-Chip modules in individual sockets, but the reader was a
photoelectric type with mechanical sprocket feed. Sold it two weeks later
to a PCB fab house, for over 20 times what I'd bid it for. Made the Boss
grin...

  Cheers
