Your method (drill with deepwell socket) was fine. Good on`ya.
Suggest next time only two things:
Just set the propane torch on the bench and hold the drill in your hand.
You can operate in the kitchen that way w/ good light.
Get some 500° TEMPILAQ
and paint a small patch ¼" below the shoulder
When it goes transparent upon heating the neck/shoulder well above, dump the case.
You're precisely/repeatably done
