Hi everyone,
I have an old Ludwig Supraphonic 14x5 with the keystone badge (serial number !6220!). According to the sn its from 63, came with COB hoops but ludalloy shell.
The chrone is flaking off really badly:/ and I am trying to figure out what to do with it. Does anyone have any experience with sandblasting a ludalloy shell? It seems pretty impossible due to the bearing edge. I cannot imagine someone removing the chrome from the inside of the bearing edge or the top of the edges without damaging the ludalloy or deforming the shell (chrome is harder than alloy).
Another option would be electrolysis but im afraid that the shell could get damaged in the process.
Has someone here tried any of this? Please share!
