Technical Details

Al Fincham got me this Brew BJ Ropewalker from Rocksport in 1981.

The Brew BJ Ropewalker, Version A is 102 mm. tall, 60 mm. wide, 43 mm. thick, and weighs 192 g. The shell is 1.8 mm. stainless steel formed into a U-shaped channel. The cam is cast aluminum. The axle pin is stainless steel and is secured by a thin spring wire. The end of the pin is tapered, and projects about 12 mm. beyond the spring wire hole.

There are no markings on the metal parts of the Brew. The sticker says:

Comments

The Brew BJ Ropewalker was a British ascender manufactured around 1980. The cam so closely matches the Gibbs cam that I believe that one was used as a pattern. The tapered axle pin helps align the cam with the shell, but I’d prefer to cut about 10 mm. off the pin instead.

Technical Details

I acquired my Brew BJ Ropewalker, Version B in 2017 as part of Bob Thrun’s collection.

The Brew BJ Ropewalker, Version B is 102 mm. tall, 60 mm. wide, 10 mm. thick, and weighs 178 g. The shell is 1.8 mm. stainless steel formed into a U-shaped channel. The rope channel is 16 mm. wide. The axle pin is stainless steel and is secured by a thin spring wire. The end of the pin is tapered, and projects about 12 mm. beyond the spring wire hole. The cam is machined from aluminum allow plate and then anodized. The cam radius increases from 16 to 38 mm. over an angle of 67°, giving a 36° cam angle. There are nine rounded teeth on the cam.

There are no markings on the metal parts of the Brew. The sticker is the same as on Version A.

Comments

I prefer the harder machined cam to the cast cam, but there is nothing wrong with either.
