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?

"That [censored] is [censored] up."

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:

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 (
http://www.jbweld.net/marineweld.html ), 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?

If none of your local bike shops can weld alloy, ask them if they could make
a rough drawing of what the dropout should look like, or get a photo of the
dropout in a good frame, then take it to a welding firm (often they'll
mention being able to weld Alu in their ads). They'll be able to fix it up
for you and it'll most likely cost less than it would at a framebuilders.

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.

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

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.

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