cog on

Cog is drilled and mounted on the Project Curbside wheel.  This was a bit of a task.  I started with a very small bit, then had to drill the holes up one size at a time.  I tried going straight to the finished size but the steel just hardened up immediately.  A better cutting fluid than WD-40 might’ve helped.

Notes to self: 1) gloves are a very very good idea when holding a cog down while drilling 2) if you ever have to replace a cassette, Miche makes theirs from some extremely hard stuff.
