Bernie used this method to save a really nice but damaged Lejeune. I'm also confident in the repair. The machined part he used to splice the joint is pretty beefy, and the TIG weld looked bomber. The repair was very quick and inexpensive, and the Lejeune steers great, no-hands too (gasp!).
A couple thoughts. Ask him if it will work if the bent portion extends low on the steerer tube. Also, make sure that the splice is done low enough so that it doesn't block your stem from being inserted far enough. It might not work on small frames. And when he grinds the TIG weld down (so that the crown race can pass over it) you might ask him to leave on maximum bead for more strength.
Good luck!

Subject: Re: [CR] steerer tube repair
Bernie Mikkelsen, a frame builder based in Alameda California, makes quick work of such steerer repairs by machining a tube to press fit into your fork's steerer and a new steerer any length you want, then TIG welding around the outside of the join in your steerer.
Fast, effective, chrome and paint not affected, and relatively cheap.
Bernie showed me a fork he'd repaired that way and I'd have 100% confidence in the repair.
Personally, I've developed techniques to quickly machine a damaged steerer out of the fork crown and silver braze in a replacement. Effective but not fast or cheap as the paint is normally damaged.
