Aad cleaned up the big horrible steering lock bulge on the neck. Note
the 3 gaps
in the grinding disc; because of these you can see what you are doing
the disc seems transparant when spinning! More unneccesary brackets
removed and we started transforming the bolt-on hardtail to a weld-on.
The diameters of the tubing of hardtail and frame are different, so
a hollow conical piece that will connect the pieces.
To be continued..
