Any Way To Fix This

I bought a frame recently, but the original carbon fork was not included as there's a crack through the aluminium drop out. See the picture. The original owner said I could have the fork if I could find a way to get it repaired. I doubt its possible, but has any one ever heard of a way to replace the drop-out on a carbon fork.

The dropout is easy to replace. As a bonus, it comes with a whole new fork attached to it.

Seriously tho, the bonding agents (glue) used in these things are pretty tough, generally tougher than the things it is bonding together. If it is possible, I seriously doubt it is a practical to separate the two pieces without damage to the carbon blade.

Replacing isn't really possible as far as I know. You could fix it with a weld, but would the heat harm the CF fork? Would it harm the bonding agent? Dunno, but 10,000 degrees is rather warm...

You can get replacement alu or carbon forks for < $100. I've been riding around on some cheap-ass Supergo CF forks (chromo steer) I got for $75. I've had them for three years. No problems, good ride. Not the lightest forks out there, but I couldn't care less.

Craig Calfee repairs carbon frames and may be able to replace the dropout. However, I doubt the cost would be worthwhile even if he could do it.

Kestrel sells their EMS Pro carbon fork with a Cr-Mo 1" steerer or an Al 1-1/8" steerer at a list of about $150 and a street price well below that.

That's pretty well what I thought, but I wanted to explore the repair path before plopping down some of my scarce bike cash.
Anyone have any experience with the Nashbar carbon forks?

Seem to be half the price of anything else out there, are they half the quality?
Thanks

Here's a question for you to ponder. Is twice the cost carbon fork necessarily going to be twice as good? Are you sure about your answer?

I'm familiar with the concept of diminishing returns, there is a point near the low end of the scale where price really does matter. Bought much from Wal-Mart lately?

Actually the point of my post was not diminishing returns. It's NO return.

I would have no qualms about using the Nashbar fork. It has to be made in the same Taiwanese plant that builds about the same fork under a dozen different names with more prestige. It may not be the lightest or the best finished but it will certainly be functional

Wouldn't be tough to repair for a skilled welder. Grind a V-notch laterally across the crack at the bottom of the U in the drop-out. Zap it with a TIG welder, shouldn't take more than 5-6 seconds and that's it! By joining just the beginning of the crack, you'll keep the dropout from spreading wider and wider and elongating that crack. ALso keeps the heat as far away from the glue-joint as possible. Might even clamp some plyers on between the weld-zone and the fork to act as heat-sinks.

I'm pretty sure the OP likes his face.
