Hi Doug: Those "sleds" on the SF10 are the forward termination pieces. The little "buttons" close to the strings are the allen-head screws which attach the piece to the Capo Bar. The only way I can imagine the string hitting those screws is if for some reason they were not screwed in tight in the first place. These termination pieces are the replacement for the earlier termination Bars which came out on the SD10 in the mid 60s. These pieces are a result of much experimentation in the late 60s and early 70s. The original bars were straight, necessitating an alteration of the hammer line to keep the strikepoints reasonably close to where they should be. The newer pieces allowed a curved termination line at the Capo and hence a straight hammerline. These hardened steel pieces also have a very special plating which provides better lubricity for the string movements.
