Ca glue on ribs

[David Love]

While I can’t give you a technical reason, I don’t really like the idea of
trying to secure a loose rib by wicking in CA glue.  It’s one thing to fill
the void around a loose bridge pin or tuning pin, but I’m inclined to see
failure in this instance.  I think it would be better to work in some
regular old Titebond with a thin feeler gauge and find a way to clamp it.
If, after applying the CA, the joint does fail anyway, you are then "stuck"
with the problem of cleaning out all that crud before you can properly glue
it back together.  I just don't think CA was meant to be used for this type
of repair.

Yes, thin CA. What you see might surprise you. When you apply CA at the top
of the rib it might run all the way through and out the bottom on what looks
like a tight joint. When I see that happen I’ll use accelerator to make sure
glue sets up in the void before it all runs out.
 
I’ve also applied it to bridge joints. Sometimes you’ll see the glue suck
right in.
