3. The tow is connected to the linkage on both tow ends. The tow runs a full rotation around the cam. I put a drop of CA on the tow/cam to prevent slippage.
Thanks Vincent, much appreciated. Great work! I may well scratch up a OD 2-2.5m ultrabatics ship this winter with a madstab; if I do I'll definitely be using a setup like yours!
