Making a 16mm cone key for tightening the cones of the rear wheel of my #Brompton. Instead of buying a default cone key from the bike shop I rather make it myself from a standard wrench. Why? Because bike tools are made from poor quality materials and expensive.
The process is quiet simple. Instead of filing the wrench (which is made from a chrome-vanadium alloy and then rather hard) I decided to do two cuts. I'll show you the final result.
