Do you have the thickness and diameter of each part ?
Also recently i order some bearing for a Campagnolo hub and discovered that you need to know how precise you need the fabrication and also the hardness of each bearing. I don’t know if that would be also the case for this DIY kit ?
Grade defines tolerance and Rockwell HRC method for hardness.
Also because it is so cheap the minimum order is often 100 pieces, so If people would be interested I could order from china and then send it to some people in this forum.
If there is a kit available i would in this case be interested to buy it to save some time…as it is not a cost problem
