Locate the newly capped bridges via triangulation. The triangulation was down when the old bridge was still in the piano. The location data is transferred onto new bridge.
Mark the bridge location, double check with plate in, then use drill bit to locate soundboard button which will be screwed from the bottom of soundboard into bridge body. Some of the holes are for installing weight under bridge if needed. The weights may be added to improve sound quality.
Before gluing on the bridges, the board is sanded smooth. Limited on the press, we glued two smaller bridges, let dry, then glued on the big treble bridge.
Lastly, the soundboard buttons are installed to further fasten the bridge and soundboard together. Next, the board will be finely sanded. The shop owner will spray sanding sealer and finish on it.
