Shroud Tensioner

This probably won't interest most readers, but a fellow F-24 owner wanted some images.

Because the F-24 folds, a quick release of cap shroud tension is required. Pulling the shrouds aft with a tackle is a simple way. This can either be a cascade:


or a straight tackle:


A cascade places only 1/2 the load on the blocks and can thus be built using lighter gear. This is commonly done with vangs, for example, which also have a small range of travel. The only advantage of a straight tackle is that it can be adjusted through a greater range.

The PO (previous owner) probably used the blocks in a 4:1 tackle. I'm not sure why he went to a cascade, but it works very well. I assume he went to 2:1 on the blocks to avoid over tensioning, but I may go to 4:1 (the pulleys are there ) to make it easier to adjust under load, simply remembering not to yard on it.
