Here is a little project that has been 18 years in the making.
In 1989 I bought these 175mm arms from a kid at the track that had improperly tightened them causing stress fractures around the pinch bolt.
I've ridden them lightly for years, but it's kind of like a windshield crack, it just keeps growing.

Today was the day I finally made a solid split in them.

Any opinions on how to weld or braise these for strength (not show)? I WILL be fixing them because I won't pay quadra-angle $100 for just one arm on ebay.

One of those "How would Rod Miles do it?" questions.

Curious to hear input on the solution.

Thats easy, just a normal weld, grind it down, chase the threads, rechrome. I wouldn't use brazing at all, not strong enough.

I took a good look at the arm today and realized with minor leverage the whole end could be removed. This showed that there is a washer insert. How they got that secured to the arm originally I'll never understand.

Anyway, welding just the outside left 3/4 of the washer unwelded and loose. That solution was out.

I ground away the whole side of the arm, per the pic above, added weld in layers, then reformed the shape on a standard wheel grinder.

After that the hole had to be redrilled using a drill press and lots of dremel cleanup.

Elbow grease with fine sandpaper should make the fix mostly undetectable tp the average observer.

Any idea's on how the wire weld will affect the cromoly along the weld line? (I'll never race or thrash these too hard so I'm confident they'll be safe for my usage)

Thank you Quad for the generous offer on the weld! The folks are this site are THE coolest!
