Renovating a Shure mic

N

N_Cook

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.

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
