Now I finally found the time to timber.
I decided that I’m not able to cut the plates with my jigsaw accurate enough to guarantee true running of the wheel and ordered three NC-milled plates (6.5 / 12 / 6.5 mm) from a company nearby.
I printed stencils from my CAD construction to mark all holes. As the middle plate has exactly the inner diameter of the rim, I had to file grooves for all nipple eylets
It perfectly fits the rim.
