It is a long shot but it is about a 2minute process to chuck up the tool in a metal cutting lathe and take a few light cuts inside the tool to open it up enough to clear the axle. Problem is finding someone with such a lathe. One possibilty is community or trade schools with metal shop training. I am still using my
1998 Shimano tool, had to open it up twice, once for the early splined BB, and again a few yrs later when the current octalink came out. Works fine on my one ISIS bb also.
