While still in grade school, I started to make a copy of a Peck Hook using a hacksaw, file, and drill press. I stopped when I got this far. Its embarrassing to look at, but it works.

Embarrassed by Version A, I resolved to make a satisfactory version quickly after getting my own milling machine. I rushed to complete this before going on a trip, and made a careless mistake by making the spine 1/2-in (12.7 mm.) wide instead of 5/8-in (16 mm.). The result is aesthetically unbalanced, so I quit before finishing the top. I must hang my head in shame.

Alan Blackshaw's Peck DescenderEmbarrassed even more by Version B than A, I finally took a picture of a real Peck descender (from Alan Blackshaw, Mountaineering, from Hill Walking to Alpine Climbing, 1968, provided to me by Stéphane Pennequin), used the rope for scale, and made a better copy from 25 mm. 6061-T6 plate, using a milling machine and files. At least this time I made one realistically portrays the main features of the original; however, I did not get the size right because I assumed that the ropes in the picture were larger than they actually were. Compare this version to the real Peck descender that I acquired in 2012. My Version C is 1/3 larger than the original.

The Peck descender works by having the rope wrap around a vertical shaft. I prefer to have two or three wraps, since one does not provide enough friction. Like most vertical spools and similar devices like Patten’s Hook, the Peck induces a lot of spin on free-hanging rappels.
