Scott - I did the same thing as Joe, except I used high density PE (ordered from McMaster Carr). I routed a step in them that would sit in the mast gate opening, cut them to length and width, drilled 2 holes and drilled/tapped holes in the mast. Rounded edges. Incidentally, the same material makes great mast blocks (if you partners have been enlarged). email if you would like a sketch or photo. seth.hunter@i-stat.com
