Rear derailuer repair... worth it?

Hello,

I've found a nice Ciöcc for sale ('87, Columbus SLX, D/A 8sp hubs, cranks, front/rear derailleur, post, headset).
However, the derailleur hanger snapped in half so half of the drop out is still with the frame and half is with the hanger.
The price is very reasonable, even for the parts alone, however, I'd like to find out more regarding how difficult it is to repair something like this.
I've heard a frame builder could repair something like this but what does that do for the integrity of the new hanger? How does it hurt the resale if I want to turn it? Lastly, how the heck do I find a frame builder interested in doing this (check my LBS, I gather. Probably won't be too hard to find someone in Portland, OR)?

Thanks, guys.

A framebuilder would most likely replace the whole dropout. And if it's a CIOCC with a chromed rear end, you can kiss the chrome goodbye, at least on that side.

Thanks Bobbycorno.

The dropout itself is painted (attached is a shot before the incident occurred).

But the chainstay is chrome. Would the drivetrain side chainstay be sacrificed?

Now that I think about it, even if the chainstay isn't sacrificed, I'd have to find the same color paint for the dropout, which could be difficult.

I just dropped off a Raleigh Pro with a broken dropout at Mikkelsen's shop. It had snapped off at the dropout adjustment hole, he suggested he would weld the pieces rather than replacing the dropout. He said the repaired dropout will be stronger than the original, albeit without the adjustment hole.

You're not going to be able to replace the dropout without affecting the chrome. At least a couple inches on both the chain stay and seat stay will be affected. Here's a Trek I'm in the midst of repairing -- the dropout is just dry-fitted right now, but you can see the heat affected area extending up the stays:

You may be able to save the most of the chrome with a wet rag wrapped around the stay. Especially if only the hanger tab snapped off. I wouldnt mind riding a frame with a tab welded onto an otherwise solid dropout.

I bet that paint burning made a swell smell.

you're looking at $50-100 for the framebuilder fix and a repaint/rechrome of at least that area. soooo, minimum of $100, but more like 200-300.

or, you could just hack off the rest of it and try using a separate hanger.

Campy used to supply just the hanger with a slim run of steel to match the bottom of a DO. I had 2 brazed on by a good frame builder (Ed Litton) one was to a Simplex DO on a TdF so I could use a standard RD. If done right, the repair will be strong and almost invisible, it will ruin any chrome on the DO, but not any on the chainstay. You have to find a frame guy with the old Campy bit, or willing to grind one to match from a donor.

Saw that ad in CL a couple of days ago. You may want to contact Robbie at the Recyclery store downtown. He may have cost effective sollutions. https://www.therecyclery.com/

Thanks SJX. That's good to know for the future.
I would consider repairing this frame but it's too big for me anyway. If it was dead on my size, I'd push harder. It's a nice looking Ciöcc!

I took most of it off with a wire wheel before pulling the broken dropout.

I can't believe nobody has suggested this so far:

Hack off the offending remaining bit of the hanger, and Drew the other braze-ons while you're at it. This opportunity is a fixie-fanatic's wet dream
