---------------------- multipart/alternative attachment Hi Denele Remember me? U' of Ark piano sale? Any way what a pain Establishing the height of the bass bridge is simple but you'll need to repair the counter bearing height bar first. . The bass strings usually sit approx. 3/8 inch higher than the tenor wire so the counterbearing bar is probably that plus an amount taller if it sit in a hole as do some. These are not difficult to make. Also the difference in your hammer bore is the other clue. Pull strings from the hitch to the bearing bar at each hitch & tuning pin hole location Drill accordingly Once this is done pull a string from the counter bearing to the hitch pins. Measures the gap/space between the string & bridge body at each end. Calculate this distance plus 2mm & this is your new bass bridge height. Cut maple fit & glue. All is not lost. After the new cap is on stretch a line from each hitch pin to the appropriate tuning pin location. Scribe a light pencil line along side the string. Do this for each string. Draw parallel lines on the front & back of the bridge cap 5/16th off each side. Now your bridge pin holes can be drilled accurately. Put an awl mark at the intersection of lines as a guide for your bit. Use the appropriate drill bit & drill the front holes leaning towards the bass ( about 18 degrees) & the back set the other way. This will give enough stagger in the pins. Bevel the edges. This may be a curved bridge but the procedure is the same. Hope this helps. Or fly me out & I'll fix it for you. Grin Dale We could use some help from anyone who might be able to send us measurements for an old upright, Carlisle ser no. 47295 (mfg 1904). UPS lost our shipment to Schaff, which contained the bass strings, bass bridge cap, and bass bearing bar. We are most troubled trying to establish the height of the bass bridge and the bearing bar. We would very much appreciate anyone who could find a sister instrument and send us these crucial measurements!! PLEASE respond directly to my email since I can't keep up with the whole pianotech list!
