Presumably this is possible only with a QCTP without removing the toolbit
from the holder? If you took it out of a lantern or a rocker you will never
be able to re-insert it in exactly the same way. Or am I missing something?

When I have difficulty with a fit I make the start of the bore or the
shaft slightly tapered by filing or cutting steps, press the parts
together enough to make marks, then cut down to almost remove those
marks. Candle flame soot or marker ink makes them easier to see.

OK. I have done something similar with a Sharpie pen but not in this
context. Thanks.
