I purchased a Guerciotti neuron steel bike that was upgraded with a carbon fork.
The seller threw in the very nice chrome Guerciotti fork that was cut off right where the steerer tube connects.
Would love to use this fork on a same size pista frame I have, that needs a fork.

Can it be re-welded?

If yes, should I seek out a bike builder or can any welder do this fix?

I'm curious why they would do such a thing.

Normally I'd say bring it to a builder who can mill the steerer remnants out and silver in a new one. Except I hate that fork crown so much! Chrome complicates things too, though your FB might be willing to braze without removing the chrome. I think the cancer-causing hexavalent chromium fumes are more a problem with higher temperature operations, like welding. Don't take my word for it though.

Still, a decent replacement fork can be got for less than that repair would cost, so I'd start hunting in craigslist and ebay, or a shop that sells used stuff (we have a couple good ones in Seattle, not sure where you are). Even if you stick with Guerc-pantographed ones, there are several on ebay right now. If you could live with a plain crown (no logo) then choices are endless. I got 700 hits on (track,pista) fork

Good luck, let us know what you end up doing.

May have had a frozen quill and didn't want to deal with it.

Yeah Mark, I've done that a few times before. Last time I did a chromed one I reamed out the original steerer, if you try to heat it up so it'll come loose the blades will fall out as well!.

The key to keeping the chrome intact and safe is to create an air barrier using silver flux. A lot of the flux comes right off with heat, so I apply in several layers until I build up a good "crust". To be double safe, I do this outdoors and wear a proper mask. My day job is in the semiconductor industry, we have potential exposure to a lot of nasty gases that most people will never encounter, so my work mask with proper filters is utilized.





If you look closely, some silver spilled out of the brake bolt hole in the fork crown while brazing. Rather than try and remove this, and probably damage the chrome, we figured the brake would hide it.

Might be easier and cheaper to just find a replacement, if one can be found in good shape and with a long enough steerer, as Mssr Bulgier states.

As far as ugly goes, we sold a lot of Guerc out of Orinda Spoke and Pedal in the early 80's when I worked there. I think we were one of Ten Speed Drive's top dealers, so I have a bit of nostalgia for them.

Yes, Im sure that was the case since cutting off is more difficult then detaching the quill.

joesch

Yes, need somebody with @gugie skill to do it correctly and safely. Its a nice Guerc which would have fit nicely on the target 58 pista Guerc. I did the 36@y searching and the nicer cromo+ metal forks were approx $100 with some cheaper models more iron metal for less than $50.

I did the 36@y searching and must have missed those offerings. Probably close in cost to sending mine to somebody skilled like @gugie to fix and then return.
