Rim joint seam problem

trg said:

I have a rim that's less than 2 months old that has a rim seam that is
uneven. It was ok for the first 200km or so, but now is noticeable when
braking. It has a raised lip up when the wheel is revolving, so it catches
the brake pad at each revolution. I'd imagine the effect would be less
noticable if the unevenness went from high to low instead.

yes, but then it'll then be low/high on the other side...

probably your best bet. you'll need to keep monitoring the situation if
this was ok initially but has suddenly become a problem - you may have
some movement between the hoop ends.

Will the gap keep
growing?

possibly - depends on whether the internal socket has failed. next
time, get a rim that's both welded & machined - you'll /never/ have this
problem again.

How are the spoke tensions around the joint?
If they are even, then a careful smack with a bubber hammer backing the rim with a block of wood on the floor can assist in the alignment process.
Other mechanical manipulation can help, but proceed with caution, so you don't overshoot or make the problem worse.

I would have thought, were this a front wheel, that the simplest way out is
to turn the wheel around, change the skewer, and if needed, the tire. Is
this too simple ?

It is a front wheel, and I plan to turn the wheel around. Hopefully that
will help with the sensation, as well as preserve the brake pad, but will it
fix the problem?

I've used both an adjustable wrench and a Vise-Grip to solve this
problem on different occasions.

Having just read Jobst's posting re: tensioning a wheel without a rim
joint insert in place, I'm wonder how I managed to accomplish this.

That sound destructive if you don't loosen spoke tension first. That
has got to cause dents in the rim.

You must have loosely spoked wheels. The compressive force in the rim
joint of a tight wheel is about 1000lbs.
