the disc solution is really a good one, you can paint it , polish , sand it and remove it if you want, the cost for made the disc is fairly cheap if 15 peoples want it i can do it easily (in fact my subcontractor)
We need more details Yann.
Where are you? Can you give an indication of price?
hi for do this you have two way to do it , one is cut the ring and press it depend on the thickness you will need between 100 to 300 ton hydraulic press, the second way is use a square sheet and cut after it's more accurate but also the price is not the same more time consuming and human manipulation.
the cost is based on the quantity, but i hav 15 peoples want that made 60 disc (2 by wheel) in my eyes that will never be more than 100 US$ (surely lower), after that have an other cost witch i can't fix it now is the treatment will be asked for: Paint, polish , sanded , chrome and so on
Can be metal or alloy , but the best it's Alloy because no rust and more easy to maintain
i am in Singapore, my subcontractor (and a friend) made part for Roll & Royce plane so i have no doubts about the quality
Voila voila
