<DIV>You have just pointed out the easy way to square up the head
where the glow plug seats. Take a headless 10-32 bolt and screw into
the glow openning from the bottom. Use a lock nut if possible. Chuck
the bolt in the lathe and cut the glo washer seat. Who do I bill for
this ? </DIV>

<DIV>Are there end mill bits available with a square central
locating shoulder built in? Seems that may be the easiet way to get
what Earl suggests. Another two step approach might be to use drill
rod that just fits the hole as the locator first, locking the head
down in the fixture, then switching to the bit and touching the
surface to square.</DIV>

<DIV><FONT face=Arial size=2>Assuming that the problem is
lack of perpendicularity between the threaded hole and the
gasket surface - find a "friend" that will set the thing up in a

unusual that he would not catch this.)</FONT></DIV>
