I brazed a fork crown to the non-reinforced end of a steerer tube - advice?

[Astrapower]

Hi guys

Newb error alert - I wasn't paying attention and brazed a fork crown to the non-reinforced end of the steerer tube. The steerer tube is a Columbus tube - 1.55mm thick to 2mm thick at the helicoidal reinforcement end.

The fork is a disc specific fork with a long Willtis tab and reynolds 853 disc blade. The crown is a Pacenti MTB.

The fork will be for my own use on a 650b porteur commuter.

As far as I can think I have three options.

1, leave it as is and ride it.

2, cut of the steerer tube at the crown, bore out the remaining brazed steerer tube in the horizontal mill, re-brazed the steerer.

3, bin it, learn from it. start again.

thoughts?

Why not just heat it up, remove it, and then braze it back in the correct direction?

The material doesn't cost that much.
Buy another two components and start over.

Use it for some non load bearing artwork.

If I were making a weight weinie frame for a small guy who will only ride on rollers I'd let it go. But few fit that model. I agree that it's do over time. Cut off the steerer at the crown and save that for some other project. Then cut the crown across the still in place steerer and see your work from the insides. Andy

Is this a question or a recommendation?

[EricKeller]

is it built into a full fork at this point?

The best course of action is to build new. I'm not sure I would trust myself to make a good bore in the crown, but that would work. Leaving it, removing it via heat, and any other compromise just isn't worth it. Steerers take a lot of cyclic load, there is a good reason why they break.

[Mark Walberg]

If you really want to save the steerer, then braze a crown on the other end, then cut the first crown off.

[EricKeller]

no reason not to cut the crown off first if you are going that way

Thanks for the advice guys.

If you're going to build other forks with the same crown you can turn this one into a device for marking the fork leg cuts. I don't have one and so can't post a photo but you can remove the floor of the fork leg sockets and open the sockets up a little so the legs fit through. Remove the crown spigots so you end up with what resembles a twin-plate crown that has only the upper plate, or leave them in and make set-up adjustments to account for the thickness of the crown plate for marking the leg from the upper surface of the crown. You can then quickly and easily mark the legs for cutting per whatever length is needed.

It's not a necessary tool, might not even be relevant to you, but you're half-way there and it might be more satisfying than binning it. Or braze some cheap blades in for practice.
