Update: it's finished!
Next up is to make a nipple shuffler like this one from Wheel Fanatyk:
It's a simple but ingenious tool with at about a 100-year history in wheel-building factories.
Now I'm Jonesing for this gorgeous Morizumi spoke threading machine which eliminates the need to stock a wide range of lengths for each spoke type/colour while enabling perfect spoke lengths.
Although all these tools are aimed at bicycle wheel-building, the theory and many of the techniques apply equally to motorcycle wheels. So I have a plan to add tooling and build motorcycle wheels for MX and ADV riding.
More to come on all this in a future post!
