Russian Bobbin

Technical details

I acquired this bobbin in 1994.

This bobbin is essentially a copy of the Petzl bobbins, but features a spring wire gate. The disc that the spring is attached to is slotted so that it straddles the frame It is held in place by the ends of the wire spring.

The main bollards are turned from aluminum and appear to be well-made. The bolt for the top one is off-center, and there is a second tapped hole so that the upper bollard can be reversed when worn. The lower bollard bolt is centered, so this one can be reversed also. The bolts are about 1.5 mm. too short to extend completely through the nuts. The top post is stainless steel. It fits through a stainless steel washer on the back side of the frame and is staked in place.

Comments

I feel that the spring wire gate works better than the stamped gates on my Petzl bobbins. The finish is a bit crude, but from a functional standpoint, this bobbin is fine.
