The treble stay and slider arrangement has been the source of a bit of head scratching. The original idea was to use a special type of slider pivoted just below the bearings called a pendulum slider. This type of slider can work well in tight spaces, but sometimes it bounces against the stay and the vibrations felt on the rope.
After a recent visit by Matthew Higby to check on progress, the idea came up to use a version of the traditional "peg and latchet" type as here at SS Philip and James in Leckhampton.
After taking a few measurements I fabricated a trial version using some scraps of wood. This was fitted tonight and with the bell silenced using at old bicycle inner tube, and the bell was raised to test it out. Fortunately, all seems to work well.
The treble set at backstroke.
and at handstroke.
The stay is a bit long, and will be trimmed to length. The slider will be remade properly using steel plates and it will have adjustments to make sure that the bell is not to light or deep set.
