Holy slag inclusion Batman!! It pays to tinker.....

Re-building my "C" shadow continues to throw up challenges and surprises, here`s the latest:

Having reamed out the worn hole in my F55 balance beam, made a nice new oversize F56 pivot,stove enamelled and fitted it,I was well chuffed-no slop at all.
My attention was drawn however, to a slight misalignment to the cable on the offside. Seemed to me a judicious "Tweak" of F55 in the vice was called for, and on doing so, I was surprised at how easily it shifted when I applied a little pressure to re-align it.
It soon became clear why. I noticed a crack appear in my nice new stove enamel. Hmmm, closer inspection , and a touch of probing and "OOOH-ER"- the thing snapped in half to reveal about half of the metal was comprised of what looks like a casting fault- a roughly spherical, rusty inclusion in one half , and a corresponding cavity in the other.

Good Job I went to tweak it I suppose, better than finding it out coming down Hard Knott Pass!!!!. Sleep tight, Bob Cottam.

I figure you have a warranty claim there - on the basis of goods of un-merchantable quality.

it is an inclusion and not H/L crack that has corroded? guess from the desciption it must be casting fault.
Out of interest this work would have been outsourced to foundry?
As you say, a bit of a pain but not as painful had it occurred on the road.

It's a shame to find that just as you need to fit it,and after the work you put into it..
BUT better to find out now.Imagine you disgust at the quality of Vincent parts when you need to grab a big handfull of front brake and......Ping...OH S--T ...BANG.John
