What do I do with Story&Clark/Yamaha 158 grand?

[Farrell]

I've heard of this before. Can you elaborate on the nature of these plate plugs? How are they placed into position - what is the manufacturing steps. Are they in any way part of the block? Are they bonded in place somehow? Are they drilled prior to installation? Curious minds...........

I've always thought that a neat pin block renewal, when not pulling the plate, would be to drill 3/8" holes right through the plate and block (or whatever size that would be just slightly bigger than the original plate holes) and use 3/8" high quality plugs (same size as hole in plate and block - making sure to have a very snug fit). But trim the plugs flush with the plate top. That way you would end up with something akin to an open faced pinblock with a very hard (iron riddled with maple freckles) 1/4" or 3/8" top skin. I should think my epoxy addiction might be problematic in such a case - better to use Tightbond or something that would not bond the wood real strongly to the cast iron plate.

Are the Yamy plugs in there that tightly that they function like my above scenario?
