Mast step replacement. A repressed memory. Plywood
encased in fiberglass rotted out (surprise!) so same
encasement now contains 2.25" Al plate embedded in
Chockfast, a marine bedding compound, and West system
epoxy (we tinted it blue). The gold is the mast socket
(all Al was coated in zinc chromate), held down by
four tapped 1/2" bolts. Missing in image is the 100
peso silver coin that went in just before mast was
reset (the second time). Original rebuilt stepping was
5mm out on 250mm run (1:50 pitch) and the mast leaned
against the cabin top. An Al shim corrected that for
the second stepping. $60 per step in Mexico, not
bad...
