<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 mill aligned on the threaded
hole, then touch the gasket surface with a mill to square. (You might give
Clarence a call also - unusual that he would not catch this.)</FONT></DIV>
