glueing controversy

[Richard Moody]

The FRPins were made oval for a purpose.    On my wish list are oval
center rail pins. If and only if that would help with with those dog
leg keys where the bushings on the bass side endures all of the wear.
In that case they would have to be extra oblong.

I actually thought about putting some duct, scuse me gaffers tape on
the worn side.  Until the client could afford new bushings of
course...

You need my bushing steamer,,,   a long slot in the top of a large
square cookie metal box.

For that you need patented inserts,  extra thick bushing coth is a
big hassel.
