Lengthening a steel steerer - Is it generally safe to do if done professionally?
Should a sleeve be added inside the steerer, behind the join between the new and old steerer segments?
My opinion, it’s fine.
I have a couple I’ve done for myself and I did one for Mrs M_V to turn a threaded fork into an ahead.
Guy I know that used to weld professionally, like nuclear power station stuff, says you shouldn’t even really need a sleeve if you’re welding it. A good, full penetration weld would be as strong as the rest of the tube.
For brazing I do a sleeve. Think the wife’s one I did with silver instead of brass and it probably worked better/went together more easily but it’s going to be a lot cheaper doing it with brass.
