Brace Tensioners

In the last post on braces, I showed a drawing that had 8 tensioner tubes: P&S x main&fore x course&topsl. But I think that the tensioners need to be only on one side of each drum, either P or S, but not both. So the number of tubes goes to only 4 rather than 8. Much simpler. Each tube though now has to take up about 4" of slack. The tubes can easily be almost 3" long if placed aside the center servo (the spanker servo). An inch of pull takes up two inches of brace slack, so this should work. Details and actual dim's still TBD.
Some rough sizing based on available K&S brass tubing makes the tubes 1/4" square, big enough for small pulleys that can handle the diameter of the braces.
Hope to make a test install on one drum servo this week.
