That's funny. I worked in the trade for ten years, five as a licensed

strap called "tape".

Not being a know-it-all, I googled, and sure enough, perf hanging
strap ("iron") is the second choice of meanings for "plumber's tape".

I think this expression went out of style, probably around 1897 or so,
because it is so completely inapt when applied to strap iron.

Tef tape, OTOH, is tape and it is primarily "plumber's", AFAIK, mostly
used (when used as intended) in tapered-thread connections, where it
is frequently a "life saver" when used with the usual poorly made crap
one encounters when trying to get the water/wastewater to stay inside
the pipes and fittings and valves where it belongs.

Moreover, I was glad to learn there is a third entry in the "plumber's
tape" google list-- a vinyl tape meant to cover and protect pipe and
fittings.
Never saw that in my new work, repair/remodel, or v. limited
commercial construction experience.

Whatever. "plumber's tape" = teflon tape, by actual common usage.

I've never heard the Teflon tape referred to as plumber's tape. I've
always heard it the same as Jobst is arguing (the metal tape being
plumber's tape and the Teflon stuff referred to as Teflon). My
professional experience is only 5 years with F/A18, Harrier, and EA6B
pneumatic and general electrical troubleshooting and creating test
equipment related to it (since credentials seem to be a crucial aspect
of RBT arguments though the arguments never seem to go anywhere).

Perhaps it is a geographical argument. Living northern CA (for the
experiences above) and MI these are my experiences with it.

Get a better clamp. They're replaceable and just sit on the top of the
seat-tube.

This is the best one I've used:

Put a bit of grease on the bolt on the clamp so you're sure to be
tightening it up properly.

Adding grease would make zero difference to the tightening. The
considerable force applied for the final tight turns would really not be
affected at that point by any grease.- Hide quoted text -

Does this apply to greasing bb tapers too?

I always thought that plumber's tape'd be a piece of electrical tape
that can be used to cover a plumber's crack. I always referred to the
thin white tape that I use to protect threads and seal shower heads,
etc as Teflon tape.

You may be mistaken on that.
Thread friction and galling under the head of a steel bolt
in aluminum can be significant.

Especially when the bolt is bending a bit which they tend to do if they
don't have those clever anti-banana plates the identitibike clamp has.

Anyway it worked for me, and I thought it might have been Sheldon Brown
I go the idea from.

I found this: http://www.bikeforums.net/archive/in.../t-284188.html

It is important that the seatpost bolt is properly lubricated,
preferably with grease on the threads and on the underside of the
bolt head.

Also, make sure that the seatpost bolt isn't running out of threads
and bottoming out against the nut. If it is, adding a washer or two
may fix it.

All the best,

Sheldon [Brown]

Another problem you can get is the clamp clamping completely shut before
it's tight enough. This can be fixed by filing down part of the clamp so
it shuts a bit tighter. But preferable I think just to try a different
clamp.

Works on bottom brackets as well. Amazing how stuff actually works,
in reality. In fact come to think on, it probably helps with
freewheels to save them jamming.
