The Shoulder Stops

The shoulder stop.

Not like Barry, I put stops for the shoulder only on one side (and I put the string on the other side).

You can check the shoulder stop from this drawing, as well.

All the stops are in place. This is the left side. The top two are for the shoulder and the bottom one is for the hip.

The end of the pipe is plugged with a piece of Styrofoam but I sometimes used cardboard or plywood as well.
