See more of Unworthy's comment, above. I obtained another fork (before I saw Unworthy's comment) and cut off the top leaving 100mm above the crown. The I cut the top part of my damaged fork off (less 100mm) chamferred the ends, stuck a 3/4 dowel through (for alignment) and my son-in-law should be able to TIG weld it. I cut the pieces off with an ordinary pipe cutting tool, normally used for copper - worked here. Being steel, it took quite a few more turns! Keep posted and I'll let you know how it works. This will beat two quotes I have in hand for making a custom fork from scratch - $250 and $350. Forks for big-frame bikes are NOT lying around. Take a peek below at one mammoth steer tube!
