But, with this second hole, you risk locking it in too early in case
or normal EOS lenses....the closer this second hole is to the first,
the more likely you won't notice until you press the release
button....8-))
(or worse, not even then, since the camera won't lock up as with a
bare teleconvert, and if you don't need AF either, you can shoot
happily away, lens wide open....only when you expect the lens to stop
down in relation to shutter speed, the problem might become obvious....

Sorry, didn't mean that your first Dremel-trick caused stability
problems; only my 'slight unlock' procedure would,
handling-wise....Murphy likes my trick way too much....8-))
