Hi Tony,
Essentially that's what us keyboard geeks call the bolt-mod. Which is a
bit of a misnomer since I haven't actually seen anyone use bolts yet...
OK, you've not _seen_ me :-) But seriously, that's how I repaired my Tpye M.
I do a screw mod, which is basically the same
except I use flat headed
screws coming in from the steel plate side, and no nuts.
I am nto very happy about threading scres into palstic. The less said
about self-tapping screws the better (one of my mad friends calls them
'self stripping screws' for good reason), and I doubt most machine screw
threads would hold that will in this plastic. Putting the bolt right
torugh and htne fitting a nut seems ot be the stringest way.
When I did this with my primary Model M, I drilled out the plastic studs,
then countersunk the holes from the top. They were snug enough to hold
themselves in place. Nuts were then applied on the steel side. Just to
be thorough, I cleaned up the steel plate with steel wool, then applied
self-etching primer left over from synthesizer tinkering. Then I put
black rustoleum on top. And, yes, I checked to make sure there was
conductivity where it needed to be.
