Wheels and Brake Disc

July 2016 - One key feature of this project bike for me is the Borrani wheels.  While in very good shape, they are covered in a film of oil and have oxidized in places, however.  These will take a bit of work but should come out very nice.  The spokes are sound and in very good condition.





















The front disc brake was rusted and in need of stripping and repaint.   Given the corrosion, it took a little persuasion from a large rubber mallet to dislodge it from the bearing carrier.  The disc sat in a tub full of EvapoRust for about 36 hours.  While it eventually did the job, it also required a lot of elbow grease and scrubbing to get down to the clean surface pictured below.  I would like to try another similar product next time to see if quicker and better results are possible.

I also plan to drill the brake disc.  I purchased a 1/4" metal drill bit, and have mapped out a repeating pattern.  Radiating out from each of six 'spokes' will be three holes from inside to outside edge.  Between each 'spoke' of the disc will be two sets of two holes, essentially in the space between (inside to outside edge) of the three and evenly spaced between each row of three.  This will make 18 + 24, or 42 holes, each counter-sunk by about a mm.  I hope my neighbor will allow me to spend a few hours at his drill press this weekend!
