The winch servo is mounted on blocks that slide on rods. Springs on the rods push the servo back against the braces maintaining tension
Constellation and Macedonian both have servo trays made up with two such rigs on each tray; one for the foremast braces, the other for the main & mizzen braces.
The servo with the semaphore arms controls the driver sheet and heads'l sheets - which I'll explain below. On either side are the winch servos that control the yard braces; those of the foremast on the right, and the mainmast and mizzenmast on the left. (The winch drums are not mounted in this image). In the center are the fuses for each servo and all the wire connections. The aluminum plates attached to the winches are fairleads to guide the braces onto their winch drums. All of this is mounted on a 3/8" plywood pallet that itself is screwed to the equipment deck in the model's hull. Both Constellation and Macedonian get identical set-ups.
Another nice feature of this set-up is if a winch servo needs to be replaced, remove 5 screws and pull one plug and it's out. 1 screw holds the winch drum, the other 4 mount it to the Delrin sliding mounting blocks. No alteration is made to the servo at all. If the entire servo assembly needs to be removed, pull two cotter pins that keep the brass rods in the aluminum end brackets, the rods slide out and the servo winch, drum, fairlead, all can be removed. The entire assembly can be removed by removing 4 mounted screws in the end brackets and unplugging the servo.
When you come about in a real boat with a sail that over-laps, like a jib, you cast off the sheet as you turn into the wind, let the wind help you carry the sail across and sheet it in on the opposite side. You might also resheet it on it's original side to help push the bow across the eye of the wind. The Semaphore Jib-Sheeter allows for just that!
In the case of Constellation and Macedonian, besides the heads'ls, the servo arm itself will also control the driver/spanker sheet via a fairlead between the heads'l fairleads shown. That way it does the same job when it moves in either direction. This setup will control all the fore-n-aft sails on Pride of Baltimore; heads'ls, fores'l, and main. Another servo will control the square tops'l.
All of these interfere with being able to furl the sail in some manner, and I want to have that option. In looking at the problem I realized that on my model the tack was really more important than the sheet when sailing close to the wind because they function much like the bowlines described above, pulling the clew forward to keep the wind behind the sail instead of back-winding it. The opposite sheet hauls it's clew aft. I've added drums on the winches for the fore and main tacks. The sheets will simply run through the hull, the winch control will be on the tacks.
