Really don't want to do that though.... Originality is the key!

I found out that mu metal is a metal that SHIELDS magnetism..... Also this mu metal is readily availible so it may be possible to make an rs1600i flywheel..... I just need to know where to fix this metal and how to fix this metal?

Does any one have a flywheel I can copy?

Failing that I suppose keep my eyes peeled for him to buy one?
