    stripped thread

    Hello everyone.

    I have a beach cruiser I am currently building, but the threading on the fork is stripped. Is there any way of repairing the threads on the fork or would I have to replace the fork? The only proble with repacing the fork is that it's a 24 in bike and I am having trouble trying to find a 24 inch fork. Would a 26 inch fork work or would it mess up the ride of the bike. Thanks to everyone for all your help.

    Probably warrants a visit to a local shop. They may be able to fix the threads, maybe not. If they can't you may be able to replace the fork or swap out the headset and stem for threadless versions.

    I believe if you change the fork you'll have to change the wheel size too or the brakes won't line up, unless the bike has coaster brakes. A 26" wheel in front would look wierd or maybe cool. A bike shop will likely be able to freshen the threads with a steerer threading tool unless the threads are really trashed. Good luck. BTW I bought one of these tools from a local machine shop tool supplier for $20.00 (made elsewhere) so you don't have to spend a fortune for one.

    I have an arc welder. If your fork with stripped threads were mine, I would get another fork from any bike so long as the steerer tube diameter and threads matched. I would cut off the damaged section and just a little more. I would cut a like section from the second fork and weld it onto the steerer tube of the damaged fork. Assuming you do not have a welder, ask around among your friends and acquaintances to find someone who does have a welder and can do a good job for you. The job needs to be done with some care, but it is not rocket science.

    eBay link to a threaded 24" fork, Item number: 150115378485. The threaded length can be extended with the tool described above if necessary.

    Another idea is to get a new headset with very short stack-height. You can then chase the threads on the fork-steerer to clean them up. You'll be able to use the clean threads below the damaged section to secure the headset.

    a pro shop will have a head tube faceing and reaming cutter, face off about 3/16 on each end of the head tube,this will give you more threads on the steering tube.
