1973 hubs - material and gold finish ?????
Husabergpete:
Hi, I was just wondering what the hubs on the '73 250's are made from and what colour they were painted?
Cheers Carl.
firko:
The hubs are made from magnesium and they're not originally painted....they're treated with a sort of anodizing, creating a goldish colour. Many CZ punters make the mistake of painting the hubs too bright a gold. A sort of metallic beige is closer to the real colour than gold (for want of a better description).
Husabergpete:
Thanks firko, I thought they were magnesium and i did notice the gold tinge on them.
What would be the best way to replicate the original gold colour? Could titanium nitriding be an option??? Or does someone know what the factory originally used. Ta Carl
tony27:
The original treatment was a chemical dip, there is a guy in the states who can replicate it.

Another way to do it right is with paint, I quite like the look of this colour. Lee Holth does this & the caption mentions that it is a couple different golds & a light green to come up with this

Tony, Thanks for the info. For some reason right now I can't open the documents. Might be a poota issue. Both options sound great. The chemical dip idea sounds really good. maybe we can get some type of anodising done here. I have a contact for the Titanium Nitridring but I would say it would come up very gold coloured and not really what we want to achieve. At the moment the o/s of the hubs are a dark grey colour, but inside the front hub is a light bright gold colour, likely the original look I spose.
Anyway the search continues.
Ta Carl
