Easy threading blocks


Recommended Posts

Well, as was discussed in the other thread on this subject, if you can push more than the thread itself through the blocks, the holes in the block are too large, or the thread is too thin for the size of block.

The sheaves were made a tad wider than the rope and the slots in the block-shell was just a bit wider than the sheave to have the sheave running easily in it. If the sheave and slot were wider, there would be a risk of the rope jumping out of the sheave and jamming in the block. Both, the sheave and the shell have to guide the rope.

So, the best thing is to just stiffen the thread with a bit of fast-drying varnish (e.g. nail-varnish). You can also smooth the hole with a fine jeweller's broach - depending on the size of the block, you may want to round the edges of the drilled hole with a very fine round file in order to simulate the sheave.
