Now that I have my French thread taps for my Campagnolo 721 set, I thought I had better put them to use.
The France-sport has been waiting on this tool for quite a few months before reassembly, so it was my first frame to experience chasing threads on.
Careful preparation, included having a copy of
Barnetts manual open on my computer and drawing the correct thread direction on the frame in sharpy.

I followed the "cut and clear" procedure outlined in Barnetts. I also used much more Park cutting oil than I would have without the dire warnings in Barnetts.
All went well. When I finished I cleaned the threads and taps with white spirits using a toothbrush. I sprayed the Taps with WD40, and coated the threads with grease. Before greasing, I tried new
BB cups and they threaded in nice and smoothly.
