Myself and a frame building buddy are working on a Fat bike fork based on a Girvin. If anyone knows what the Al alloy in the fork leg is please share this info with me? Need this info for the welding and/or heat treat if its in the 6000 series.
Seems the Proflex frames were made of 7000 and maybe the forks were too since this gets around the HT issue.
Planning to call around to some local recycle/salvage yards to see if anyone has a "sorter" as a backup but that seems remote.
I built frames in the 90's and remember all the problems people had with this fork. I remember thinking it could have been done much better. A decade later and I am working on my own design kind a cross between a Proflex and the Look Fournales. This is my second post hear on MTBR when I get to ten I will start a new thread of my frames.
