[450] Failure

[Thomas Moore]

   Bob, I'm sure the mechanics at woik have some of that "PRB?" penetrant, ya know, the one that dissolves styrofoam cups (selling ploy). Or at least some good old Liquid Wrench. With a little heat applied to them with a narrow soldering iron tip....may do it.  If the hexhole rounds out, an easy-out tool may help (bring the mechanic a coffee for use of).  If ya get 'em out, a little Never-seize(bring a donut too) will ensure they will always come out.
   If all fails, ya have to drill 'em out. A small left-hand bit with the drill in reverse will sometimes "bite-in" , grab the set screw, and spin it out like an easy -out. No bite, then you have to drill most of it out being careful not to go deep, and maybe re-tap for a larger setscrew.
   But, being an old gearhead, I'm sure you know this stuff anyway.  Crap like this can drive ya nuts sometimes.

  Today's project has failed.
  I was doing fine until I ran into 4 out of five set screws frozen in one of the old loops......stopped me dead until I can aquire some more parts.
  Bummer.
  Maybe next week.
