Well I'm glad I asked because I didn't think slotted and pinned wedges were that common. Okay, next question. It may be that a wedge could loosen up over the years and have to be replaced so when a wedge is pinned, how is it pinned? I would assume a shallow slot is cut under the wedge plate for the pin and a snug fit is used but no glue, etc- that way you could take the screws out on the wedge plate, remove the wedge plate, then remove the pin and replace or re-work the wedge if needed. Is that correct?
