[pianotech] Rim joint repair

[Mike Spalding]

Al,

Thanks for sharing your method.  The piano will be refinished, so the 
main thing, after getting an effective repair, will be to minimize the 
amount of re-veneering required.  When you repaired the finish, did you 
leave the dowel end grain exposeed, or veneer over the end of the dowel?

thanks

Mike
