Considering the level of quality in most fuji items, I think I'd chalk these up to a bad batch of guides and ask fuji to replace them. I'll bet they'll do so no questions asked.

I've use only a few sets of fuji titanium framed guides and to my knowledge have never had a problem with them. In fact I've never had a problem with any fuji product. But I'm sure every company turns out a dud now and then.

titanium is a very brittle metal and at the same time very strong
and one the hardest metals to weld in order to grind titanium
you must have a aluminum oxide wheel they are pink and red
i use tianium strut on my dragster wing it is the only metal that will withstand the amount of force that is put on it. we break about 5 a year at 2500$ each titanium can only be machined with stones
do not let the guide heat up
good luck

ERik - Forget what I said about EXACTLY the same failure. Mine did not break there., it broke here: [www.fishingphotos.net]

To answer an earlier question. stress risers and crack propogation by harmonics is always in play and can cause cracking of adhesives, welds or in the metal or other material matrix proper. Amazing how this effect can part a $6000 Porsche forged crankshaft, no problem if the harmonics at certain rpm's matches even a tiny surface flaw.
