Carl,

Based on beam's past antics I would be embarrassed to give him
credibility. Apparently, you are not.

I didn't "announce" that he was faking pictures, but, yes, I certainly
intended to raise that possibility by asking him to deny that "You
tightened down the tension spring adjustment screw of your Park Tool
TM-1 Tensiometer to give about double actual values." (Indeed, he may
have done just this.)

I now believe that even if I had been clearer and more expansive, you
still would he in disagreement.

I really am sorry for that, Carl. My browser seems to be a bit balky
-- and some posters a bit testy -- but it is all my fault. I'm new to
posting to news groups obviously.

Your multiple duplicate replies to the group do look funny; my
original post doesn't even appear once. You should maybe be pleased.
You can now do an exegesis on all seven editions (joke).

Carl,

I believe my skepticism is well founded. It is based on my past
assessment of beam's credibility. I would be embarrassed if I were not
skeptical.

Not that "Dear Carl" would ever make false accusations of dishonesty.
[end sarcasm]. Heck, this is the one that that Bill Sornson and I agree
upon.

Why, yes, I do.

Do I use a pressure gage when inflating my bike tires? Sometimes yes,
sometimes no.

Do I use a torque wrench when tightening cylinder head bolts?
Absolutely.

Do I use a torque wrench when replacing brake pads on my bike brakes?
Never.

Should every mechanical operation involving a bike require investing
in a new, single purpose, $60 tool? Absolutely not.

Should wheel building _require_ the use of a $60 single purpose tool
to prevent unrepairable rim damage? Absolutely not.

Spike,

Bull****.

You wrote this, accusing Jim Beam of fraud, with as much evidence as
claims that NASA faked moon landing pictures. You couldn't have been
clearer:

"You tightened down the tension spring adjustment screw of your Park
Tool TM-1 Tensiometer to give about double actual values."

You have no evidence, no credibility, and not enough character to be
ashamed.

Stop emailing me with duplicates and excuses.

Dear Carl,

I don't care one way or another about jim beam's
photograph and see no reason to doubt its veracity, but:

http://groups.google.com/group/rec.b...ff7a01beb8e1e7

You're in a fine position to lecture people about
the rudeness of disbelieving photographic evidence
on RBT.

After years of relying on the tensioning method in The Bicycle Wheel, I
discovered - two expensive rims too late - that "rims begin to crack
from local stress at spoke holes far below that tension." I wish I had
noticed sooner that your advice (and rim design) had changed.

It hasn't. The rims have changed. You cannot spoke most
non-deep-aero rims with tension close to buckling today without
cracking the rim. It is my contention that building unsocketed rims
has brought us to this point and don't find such rims useful for me or
for recommendation.

At InterBike I saw rims that might work but they are not available in
stores and catalogs from which I might purchase them.

Sorry, it's not "uninformed." You may steadfastly despise one of my
sources of information, but it's worked well for me during the
building of oh, perhaps 20 wheels.

None of the wheels has ever failed, including on very long fully
loaded tours including rough, even unpaved, riding surfaces.

I seem to have judged the effect of the process rather well - as have
perhaps millions of wheel builders who have not bothered with tension
meters.

I don't feel the need to buy every special tool for every possible
process. My success proves to my satisfaction that I don't need every
such tool.

Dear Jobst,

Here's your idea of courtesy, a thread in which you implied your usual
vague claims that you're purely "Fact" and that anyone disagrees with
you is full of "Fiction, Lies, and Bull****":

http://groups.google.com/group/rec.b...46b665cdec7ce6

You started the thread and chose the title.

As usual, you couldn't believe that anyone thought that your own
attack might apply to you.

Again, I suggest reading Richard Hofstadter, "The Paranoid Style in
American Politics."

Cheers,

Carl Fogel
