This is really more for beginning ship modelers. Experienced ship modelers, and probably most beginners too already understand the way a standard rigging block works. It’s basically just a wooden block with a pulley, or sheave, inside a slot. There are different sizes and types, and there are single, double, and triple blocks, and just about ever wooden ship model needs at least some number of blocks.
There is one mistake I occasionally see regarding blocks. To me, it’s such an obvious error that it detracts from the entire build. But, the thing is, after a modeler completes so much work on the hull, deck details, masts, and all, I really don’t want to point out the error. So, I figured it might be best to just mention it here.
