Question: FD won't line up properly:

Quoted message said:

I'm putting together a Specialized M4 and I have an old 7 speed
Dura-Ace 7400 FD (braze on). I go to put it on and when I tighten it
down, it starts to angle outwards a fair bit. There seems to be a
little hump on it that makes it not sit even in the frame's tab for
it. I thought about trying to bend the cage but that hump or little
shoulder on it just makes it line up a little oddly. It sits so far
in the frame's braze on that the little shoulder fits in it too and
makes it angle when being tightened down. (Hopefully I'm describing it
well enough.)

The frame will have bar end shifters on it so I wasn't concerned wih
STI compatibility so I thought any braze on FD would work.

Has anyone ever experienced this problem? Or am I missing a part that
makes it line up better?

All my other FD's have just bolted on without never a problem.

Some brsnds are silghtly different shape fromothers. The
brazed pieces vary too. Lube your bolt, secure the
derailleur at the right height and as close to straight as
you can get and then just push/prise the changer until the
brazed tab bends and the changer's outer plate is parallel
to the rings when viewed from above.

Do notice that when you bolt it on, you can move the changer
up and down and also at various angles - the slot is wider
than the bolt.

It won't never be a problem (?)

I tried all that and when I get it in the right position and I tighten
it, the little bevelled washer? moves and starts putting the FD off
angled. It alsways wants to tighten over to one side. Maybe I need a
different bevelled washer thingy? FOr this FD, the washer is quite
small, on my other bike, the washer is as big as the braze on itself.
Do you think a different washer may help?

As far as bending the braze on, it won't budge, unless I should be
using a lever to try to bend it but I think I'll bust it off before it
bends.

Oh, I didn't mean the double negative "won't never" originally. I
meant "won't ever"

Thanks

I had the same problem setting up a friends' bike.

To remedy, just hold the cage with some pliers or similar, cushioned if you
like, while tightening.
Worked fine once I did this.

I also tried to bend the tab initially, wasn't so worried about it breaking,
but I didn't have any luck with a 12" adjustable wrench, it was way too
stout!
