More bolt woes, but some success.

The Ellsworthless Id is becoming a nightmare. First the cranks (which I
have decided to leave on and buy a new set for the new bike) and now the
stem. Having stripped everything else off the bike, I try to loosen the
stem and one bolt comes out but the other doesn't budge. Maybe it was
too many OTB's or too much dust from riding out in the desert (where
this bike has mainly been), but the dang thing wasn't moving. I try a
fresh hex wrench and nothing. Then the final step (or blow) was the
impact wrench and hex bit. Stripped the bugger good! One Thomson stem
down the drain.

Then I think, I can salvage this. Out comes the drill. Yeah, don't put
a drill in my hands cause it ain't pretty. I have that evil look on my
face as I lay the frame on the floor (cushioned on foam - I am not that
dumb). Try the small drill bit first (yes I checked that it can go
through metal) and it's going, going, snap. Now there's a part of the
bit stuck in the bolt! Me give up? Never! Ha ha! Another drill bit!
I'll try going through the other side. Going, going, snap! What the
heck is Thomson using? Some kind of space age material? Now it becomes
a thing of just getting the damn stem off so I can sell the frame (fork
and cranks included).

What's that hanging on the wall? Oooh a hammer! I'll just bang the
f!cker off. Bang, bang, bang, WTF? Doesn't move. So I pile the kids
in the car cause daddy's gotta get more drill bits - yeah I'm gonna do
that again). Of course they want breakfast so I turn into the
Chik-fil-a parking lot and the colored lights go on? Uh Dad, there's a
cop behind you. WTF?!? OK, what did I do? I was clearly under the
speed limit, stopped at the stop sign, didn't make any bad turns. Roll
down the window, license, registration, and insurance please. I fumble
for six minutes (yes, the kids were watching the clock as I try to get
all the paperwork out of the glove box) and hand the license and
insurance to the officer who says I'll save you the trouble because your
registration has expired. WTF!!!!!! I didn't get anything from the
state and my inspection isn't due until next October. Officer
Make-My-Monthly-Quota says the state changed the way they are doing reg
and inspections. Well, isn't that special. Comes back with ticket and
tells me that I have to leave the car here and get the reg today (the
only state office open on a Saturday) and that he's doing me a favor
because I had the kids. Call my dad to come get me and the kids, get
them bfast (we're there anyway), get the reg, go back to the car, get
the bits, and go home.

Back to the drilling and two more bits bite the dust. I figure all hope
is lost and I go and call a machine shop. Of course it's Saturday and
they are all closed. Being the INTJ that I am I just will not give up.
I go back down and shine a light in the stem. I notice a slight space
between the two pieces that squeeze the steering tube. So I take a
small screwdriver, stick it between the space, hit it with a hammer
twice and kaboom! The pieces fly across both sides of the room like
they were shot out of a cannon. Stem off (not usable) and bike ready
for sale!

LOL! It really wasn't that bad. We've had some good memories, like
when I attempted to ride those gravestones at Noble in front of Sorni.

And then there was... ouch, lotsa hurt on that bike.

RE: Thomson stems.

The steerer clamp on Thomson stems works with two bolts working in
opposition. You have to tighten or loosen them in an alternating fashion.
Loosen one a bit, then the next a bit. If you release all the tension from
one the other will bind up tighter than a tick. If one get's stubborn
tighten the other one back a bit to take up some of the pressure.

When installing one grease the threads of the bolts and under the heads of
the bolts. Make sure that NO grease get's inside the clamp area, clean with
alchohol. Then gently tighten one then the other taking turns until proper
torque is reached.

Thomson will sell you a clamp kit with new bolts and wedges so you can still
use the stem.

Quote from the LHThomson website FAQ...
http://www.lhthomson.com/elite_stem_faq.htm

Q - The bolts in the steerer clamp of my stem are stuck, what do I do?
A - The two most common reason bolts become stuck in our stem is severe over
tightening of both bolts, and then loosening or removing one bolt all the
way before loosening the other bolt. This happens because the remaining bolt
is now bearing the load of both bolts. Try tightening the first bolt back
down to relieve the load on the stuck bolt and then loosen each bolt a
little at the time alternating between bolts until they are both loose.
If that does not work, or if you have stripped the bolt heads you will need
to drill out the bolt. DO NOT USE AN EXTRACTOR TO REMOVE A FROZEN THOMSON
BOLT. Thomson bolts are special high strength alloy and are stronger than
extractors. The extractor WILL break and that will make drilling out the
bolt almost impossible.
Using a 7/32nds or 5mm drill bit, place the drill in the hole where the
Allen wrench used to fit. Apply even pressure and oil while drilling out the
bolt. You are done when you feel and hear a pop, the bolt head should be on
the drill bit. You are not trying to drill out the entire bolt out of the
stem. Once the head is off of one bolt remove the other bolt or drill it out
if it is stripped as well. You may need to tap the clamp to get it out, and
then you will be able to remove your stem. The shank of the bolt or bolts
will be left in the clamp; use pliers or your fingers to remove them.
Never resort to cutting any part of the stem off of the steerer tube.
Using new stem bolts follow all instructions for reinstalling the stem.

HTH,
Mike
 
I see you suck when it comes to wrenching. I would have used a
cutoff tool and went in and cut the bolt then drilled out both bolt
halves from the stem later.

Nothing like the lesson learned from screwing up a $100 bike part. ;^)

Mike - I tried a bolt extractor when I goofed up mine.

Yeah, I know. Don't remind me.

You beat me to it... I was about to say those same exact things. I cringed
as soon as I saw "impact wrench" because I knew that was it. I have to
admit, the Thomson stems are rather tricky because of their design...

Thomson's are one thing where the "guy" approach doesn't work. You have to
read the directions.
