Can't figure how the two bridge shaped structures above the bass bridge function? Is it a leg that defines the greater Z structure?

His design modifications produced an incredible sound from my M&H upright..... <image001.jpg> Terry Farrell PS: Oh, and after you glue in that new soundboard (hide glue, preferably) and need to clean up any squeeze-out, I've got just the solution for you...... ;-) <image002.jpg> On May 17, 2012, at 8:48 PM, Gene Nelson wrote: Just getting it apart now so I can measure and record the scale. No wound trichords to deal with but no trans bridge. – not ruling out one for redesign depending on the scale. The end of the tenor bridge come very close to the bottom board/rim structure. The bass bridge seems more nicely positioned. Bass bridge is canto levered and straight. The canto lever will go. Huge birdseye maple space filler/cut off device in the lower right and a smaller cut off bar in the upper left. Might just keep that part the way it is. Do you know if those pins that look like bridge pins – driven into the plate - that offset/terminate the wound bass strings just below the tuning pins are removable?
