Renovating a Shure mic
Shure 518SA Unisphere B. The dome was mangled from being dropped a few times
but electronically fine. Bashing the proud parts of the dome with a lead-faced hammer , dome cupped in hand , has improved that immensely . And oven cleaner has removed all the tobacco and gunge, perhaps too well. But there is an overall cant to the dome, there before I got to it, how to bring it back to axial? The ring around the outside of the dome is still in place The thread is 34.6 mm / 1 3/8 inch ? external diameter , what metalic something to screw in there rather than the mic body , or avoid lathe-turning a thread on a bar? or how to grip the interior ledge of the mount , inside the dome, with an expanding chuck or something ,lay the dome in a padded hollow of some sort, and lean into it with the bar to grip or whatever. |

Renovating a Shure mic
Did not require as much force as I thought and vaguely screwing the mesh
dome over a length of 35mm diameter plastic waste-water pipe was all that was needed, pushing dome into a block of expanded polystyrene |
