I bought them on sunday, they are 16", i will make more pics this evening...........

And i found also these set of 14" on Ebay:

You might be able to get them repaired thought it will not be cheap!
Talk to somebody in the aircraft industry as they deal with repairing alloy items

Great pictures! The first black and white one looks like a road rally or tarmac stage somewhere in Europe, guessing from the other vehicles in the background. Snow would also suggest Monte Carlo, Austria, Switzerland???

The centers are made of magnesium, not aluminium !
My budget is too lean for such expensive experiments :(
I can give them back to the former owner, and i will do so.........
 
Why not machine out the centers and put in a sleeve? A competent machine shop would have an oil tank large enough to submerge the wheels to prevent them from igniting.

Click to expand...

However you could use the centres to make molds and then get copies cast...

I guess Alpina farmed out the manufacture of the wheels to another company, does it still exist? If so you never know they might be able to help.
no harm in asking!

That wouldn't be all that expensive, at least over here. Probably ~100-200$ US / wheel. It largely depends on how you would want the sleeve to mate with the wheel bore. Doing it by a press fit would be more than a tad tricky, so making a flange of sorts would probably be the more reasonable option.
 
I bethought to make copies of them, would be no problem for me, in my machine-shop there is a CNC-Milling-Machine.
I can use high-tensile aluminium, like they apply in the aircraft industry, the styling is not very tricky....
But its a lot of work, expensive from the material and i dont know, if it is worth.......... :?
 
Making a set of replicas would be an interesting twist. You are very fortunate to have a CNC machine. How many axes is it?

It would probably be stronger, but a little heavier. To make things easier to recreate, you could use a 3D scanner. It would automatically convert the scan into a reasonable 3D CAD tool.
 
Agree the set up of the CNC would take time and the material is expensive. But once you have the design in the CNC machine it's just a case of reloading the program to make more.... :p

Is it worth it?? Maybe not in money terms but if you want the period look racing wheels then it is.... and if you can make copies then there will probably others who would like them!

Only thing that might be an issue is copyright/design rights as you are reproducing somebody else's design. I am sure for a very limited number Alpina wouldn't care, but you could always ask them..

The manufacturing is not the problem.
I have a 3-axes milling-machine, and a CNC-lathe....
The styling of centres are simple, i could make a milling-programm for that thing within 2 hours...
But if i made them, i would need approximately 80kg of aluminium for the set. And thats expensive.....
