Marc,

I'm sure if you were to contact other techs in Canada, you'd find a source...Roger Jolly, for instance...

>It doesn't matter if the bridge split is an inch wide (and I know it's not

>> Hi List,
>>
>> I'm replacing a wood bass top bridge on an old late 1890's upright (the
>> plate stops at the pinblock). The bridge split at the upper bass strings.
>> Not repairable in my opinion with either epoxy or CA. What wood would you
>> recommend using for the replacement? Any suggestions on removal and
>> installation of new bridge.

>> Sorry - no pics....
