Title: 1973 hubs - material and gold finish ?????
Post by: Husabergpete on June 12, 2012, 06:06:13 pm
Hi, I was just wondering what the hubs on the '73 250's are made from and what colour they were painted?

Cheers Carl.

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).

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

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

I'm looking to do the same to mine at the moment, so I'll be interested to see what you come up with.

Check this one out, it’s much better. You will find a good description of the process.
Apparently from some guy down Gippsland way…

This is a new colour I'm trying from Supercheap, is meant to be a proper auto paint rather than the much brighter & cheaper hobby type stuff I used on my other set of wheels. I'll leave it to set up for a few weeks before building the wheels up & will add a side by side shot at the same time

Drying in the sun, steel part of rear will be masked & painted silver in a week or so when I'm convinced it's hardened up fully

Old colour, have run this a few seasons but it's too orange for my tastes

I did my wheels with an ACE Hardware (US store) metallic brass that I think looks closer to the original finish which I don't think can be duplicated. I don't care for the really bright gold hubs.

    One of the things you notice on this forum is how many real good blokes and girls there are.  Nothing is a problem, happy to help whenever they can and willing to put themselves out to do a favour for someone they have never met and in some cases never likely to meet.
    I have been chasing the paint colour to match the original colour of the CZ hubs for a while now, not happy to just use a colour that my memory tells me is not right.    I check every CZ post just in case something pops up and the other day it did.    A post from (Scootern29) with a photo of one of his CZ wheels (to me it looked as close to being right as I have seen) so I contacted Scott.
   Without hesitation he purchased a can of the paint he had used, sprayed a 6 inch square piece of aluminium that should be easy to get colour matched and sent it to me in Australia.  Did I mention that Scott lives in the US.  This is what I mean by a good bloke.  I couldn't get a can sent over and the seller wouldn't tell me who made the paint, just suggested I come down and buy from them.  There have been others who have helped me out with this build like (Tony27) who has been a big help as well,  his advice allowed me to get what I believe to be a good match for the Side Piper tank.  Now to find someone who can match the paint.
  So thanks you blokes and thanks to the others who have helped with this build and others over the years. The knowledge on here is unreal.

Happy to help you out Zane. I hadn't heard from you and didn't know if you received the package yet. Keep us updated on how it works for you. I was kinda thinking on the color of one shade lighter would be even closer.

  Scott I tried to email you but it keeps bouncing back, maybe a problem with my server.  I will try again now and if it rebounds again I will contact you on here  via your personal messages.

If you want to have a look at the colour I'm using for my new wheels Zane, head to your local supercheap & grab a aerosol can of the Dulpicolor Imperial Gold. It only comes in small cans & I used just over a can to do both hubs both inside & out, 2 cans would be enough for quite a few coats including the front brake plate
I really like the lighter colour compared to my other wheels & being a proper auto paint unlike the other wheels it shouldn't flake off like the brighter stuff has on my rear wheel
I think including the silver I did the steel part of the rear it cost me about $50NZ & a sunny afternoon. Wheels are being built up at the moment so I can't show you a better comparison than this

Finished wheels, waiting for new excel stickers to arrive so I can finish the new wheels off

I like that color Tony compared to the hideous bright gold that most people paint them.

Yeap, I agree too.
Although I think your out come is impressive too

My 73 hubs are actually a dark grey from the factory?
So I am going to go gloss powder coat in dark grey.
Gloss powder coat is durable whilst being very easy to clean.
And mine is on course to look similar to this one of Tony's

Dark grey is what they go after the original treatment disappears, if you look somewhere that doesn't see the sun like between the bearings or sometimes inside the brake housing you may find traces of the original colour
The 76 Falta isn't mine, just a image from vintageworksbikes.com
The colour isn't quite right Scott but much better than the bright gold that my other wheels are that has lifted away from the etch primer in places. Should be a lot harder being a touch up paint for cars
Discovered no rim lock hole in the front rim which I'll have to drill when I get back from the states then I have a complete bike to reassemble before round 6 of the series
