<DIV><FONT face=Arial size=2>I think you are right I just know it isn't 10-32.
You can't get the tap just any hardware store.I have one but been a long time

<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

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