I wanna know how you broke *three*.
I mean - after you broke one... didn't a clue rake at least try to hit you
over the head about the rest of them?

Not to jump on the jump-on-Jay bandwagon (he's got enough trouble with his
broken bolts already), but wasn't he the guy who asked what the difference
is between foot pounds and inch pounds a while back?

Good Lord, give him credit for trying to do his own work. So he makes
expensive mistakes, I bet he learns from them. I have managed to break
5 drill bits in rapid succession.
Now, If I remember, there are special tools for removing broken bits or
taps. I suggest he look into a tool catalogue such as McMaster-Carr or
MSC.

I have several tiny hardened end mills from MSC. They are no wider
than a screwdriver blade and cost about $20 each and I have used them
for such tasks to get down into a bolt hole (using the dremel tool) to
make a screwdriver slot. You can also use the tiny diamond burr with
th dremel to make a "dent" atop the broken bolt for the drill bit to
start on when you drill it out.

Yes, I used the Dremel tool with a diamond grind bit to form a slot on
top of one of the broken bolt, and I used a screw driver to remove that
bolt -- successfully.

But this didn't work for another two bolts that were sunk inside the
holes. The pointy grinding bit simply could not have a good angle of
attack on the bolt surface. What ended up happening was that the two
ends of the slot were slightly lower than the center of the slot and
this weakened the slot. When I used the screw driver to turn the bolt,
I ended up stripping the slot.

But this is kind of behind me now. As mentioned in my another reply, I
found an easy way to remove the broken bolts by simply removing the
water pump base, and this allowed the broken bolts to show up in the
open, and I used a channellock piler to remove the broken bolts.

Nice to talk with you.

Glad to hear you worked it out Jay.

Sorry a non boat owner member here decided to flame you. But that is
his only reason he posts here. I would suggest you ignore him and any
*advice* he offers.. ;-)
