Screwed dropout

I'm not quite sure what he's done, or what can be done to
even bodge a fix. Anybody have any ideas?

Weld and grind?

Looks like it's either been:

A) Ridden with loose QR.

B) Had the wheel repeatedly *jammed* into the dropout.

or C) It came that way.

I think the steel washer idea would still work, myself, but
only barely...

It's alu. Pretty sure welding would be too difficult.

That was my initial guess, and I think that's probably it.
However, the picture was way worse than I imagined.

I'm thinking a thick washer with a deformed internal flange
that will fill the gap (kind of like the one at the back
here: mainlandbolt.comwashers.jpgOpen ↗). But,
I think it's risky.

It shouldn't be. Get him to take it to a competent
machine shop.

I second that. Better than jury-rigging something that may
fail on you.

You would have to heat treat after any welding because the
initial heat would anneal the dropout.

Something you could try is filling it in with some heavy
duty epoxy ( jbweld.netmarineweld.htmlOpen ↗ ), and
then reshape/grind it smooth. Not sure if it would work, but
that JIB Weld is some strong stuff... used it many times.

Thanks Bomba your help and for posting the pic and everyone
else for their replies. The thing rides OK presently with a
bit of rubbing on the brake bads, but obv. it is applying a
constant force at an unanticipated angle on the frame, so
cannot be good in the long run.

How would someone find a competent machine shop, in
Massachussets? I don't think the big bike shops have
those skills?

You could try the local yellow pages.

Whatever you do, you will need to find out and fix what's
causing this so it doesn't keep happening. My guess is a
poor alignment of the dropouts on the frame, perhaps it was
assembled improperly or has been bent.

Get some of that AL that melts with a Benotourch. And
than grind.

Was this a FS bike? Could he just get a new backend?

I'm the king of half-assing a ride with cheesily
ground washers.

That thing threw the chain every 100 feet...until it got
"nicked" as you put
it.

Check with Sheldon at Harris Cyclery. I'm sure he'll point
you in the right direction.

Same here - I think it's a weld fill, grind and re-heat-
treat job myself...
