This project was a supplementary work.
I had to create toolings to drill the frames in order to set up inserts very precisely.
Moreover, I used my own dimensions that I defined for my parts.
For developing this tool, I was inspired by the headsets and cranksets because
it’s reliable and adapted to maintain correctly the frame.
How does it work ?
1. Put the frame by the bottom bracket in the tool
2. Insert the guide in the bottom bracket & push it against the frame
3. Turn the swrew with a air tooling (M8 1.25) 4 Drill 2 holes with the help of the guide
