Soft-attach 18mm pulley block

Pulley block used for 5mm outhaul line on windsurfing booms.

Designed to be as simple as possible.

I used a brass pipe 8mm diameter and 0.5mm wall thickness as hollow pin, you can use a thicker 8mm OD pipe, just make sure to round the inside edge to a smooth radius. The pipe has to be cut to 10.2mm long.

The pulley case is held closed with the loop line by stitching. I used proper waxed sail maker wire witch help a lot to firmly thigh the block.

Reliability testing is ongoing...
