[CAUT] install bridge pins?

[Mark Cramer]

Yeah, that's what I'm chewing on at the moment Jim. I'm drilling a new cap,
and have pretty much decided to drive the pins "dry" on this one, followed
by a drop of CA at each pin. 

 

A year or so ago I did a test to see whether CA, or epoxy (via a heated
bridge-pin) penetrated the bridge cap better. After drying, I pulled the
pins then sliced through the holes on a table saw. For the life of me, I
can't remember the winner!?

 

I did this at the Banff shop, so maybe Bert can help out. I've really got to
look into those memory enhancing drinks! 

 

Any case, Ron Nossaman's suggestion was/is  that only the surface matters,
so the depth (both went several mm) issue would be a moot point. 

 

When a valid idea comes along, I think it's important to get some examples
in place in a hurry, after all it takes a few years of seasonal cycling
before any kind of responsible conclusions can be made.

I don't know if this has been said or not, but the Nossaman method of
drilling the pin deeper than normal and using a laminated cap is extremely
effective in keeping the top of the hole firm (laminated). Using CA glue and
filling the hole may negate the advantage of the deeper hole by filling it,
allowing the bottom of the pin to touch bottom, which has some negative
effects.
