looks like the answer to my own question is it depends on which chip and which adapter
since some adapters have grooves cut into them that makes positioning and sticking in the chip easier than with others that don't & some suppliers give the option of either sticking in the chip for you or guidelines for DIY so you don't have to be a rocket scientist to do this but maybe it helps?
while trying to figure this out I have also found out that people who sell these gizmos like David at
Leitax and
James Lao not only know their stuff but are also very helpful and ready to answer my dumb questions that makes the option of mixing one (wo)man's lens with another (wo)man's camera more doable than it otherwise would be.
