This is a home-made bobbin that Peter Ludwig of Austria gave to me in 1991.
This bobbin is 143 mm. tall, 45 mm. wide, 40 mm. thick, and weighs 195 g.
The frame is 6 mm. in diameter and appears to be made of mild steel. Two washers are brazed in place to hold the upper bollard down, and a home made metal tube between the bollard holds the lower one down. The bollards are turned aluminum. The upper bollard has a V-shaped groove, while the lower one is U-shaped with a 10 mm. diameter groove. The lower bollard pivots on the frame to open for rigging. Part of the lower bollard was cut away so that it clears the frame when opening.
This is a non-commercial bobbin and it has no markings.
This is a compact and lightweight design, but the workmanship could have been better. I don't quite trust the washers holding the bollards on (although the bends in the frame would probably hold if the washers failed). The sleeve between the two bollards was improvised. If this design were to be commercially produced, a piece of tubing would be substituted.
This bobbin is smaller and lighter than the others in my collection, but it works just as well on 9 mm. rope. This one is too small for 11 mm. rope, and I would have made the frame one or two centimeters longer so that it would be easier to get the rope in past the seat maillon.
For far more content, use a larger monitor and a full-width window.
Hundreds of cell phone users complained and asked me to for a simpler, mobile friendly site. In particular, they wanted me to limit each page to a small number of pictures and minimize my use of text. This new site provides what they asked for.
