To do this we cut a slot with careful skillsaw work.
Next we filed the cut clean then plugged the top of the mast with thickened epoxy.
After this set, more filing then we drilled a hole for the bolt and fabricated a cap.
For the sheave we didn't use a Ronstan or Schaefer item, but a sturdy nylon clothesline sheave from the hardware store (about three dollars).
Next, we will take it apart and varnish.
