On a model D, how many steel disc's and how many brass discs should there be?
I would replace the discs, they are available.A related question.... I'm overhauling my second ND Model D hub. Unlike the first one, on this one, some of the flanges on each copper disc have taken some serious force that has slightly damaged the ends of some of the flanges. See pic. The result are little spurs that stick up slightly, perpendicular to the plane of the disc. I'm thinking of taking the time to gently sand these down so that the disc is again smooth. I did not test the function of the hub before disassembly, so don't know if this damage had any effect on the function of the brake. Anyone have any experience to share?
Piercer, sounds like a solid idea. I wasn't looking forward to the tedium of sanding down 30+ burrs of soft copper without wearing too much into the surrounding disc. I've reached out to Scott. ThanksI would replace the discs, they are available.
Also Scott sells them, @sm2501
It is worth it. The flanges are the key to solid braking, they will start to wear with the chink like that, the it shears off and scores the hub.
Miq, thanks for the suggestion. I just saw them on ebay, but notice that this is a 17 disc set, 8 flanged and 9 regular. My hub has a 23-disc set. Did you use your NK set to replace an ND 23-disc set? If so, I'm guessing that these discs must be thicker, but that the total stack height is the same.
