Possible?
No not easily possible as you would have to remove the cap clutch before you could get access to the bottom end of the screw. I looked in the Pen Repair manual and both 51 Aero and Vac have internal clutches. They are very hard to remove without a special tool made for that purpose.
Also, it would depend on whether you are buying a new screw to go with your new jewel since the jewel is screwed into a screw that is specially threaded to fit the jewel. Damage that thread with your drill bit and you will need a new screw.
If you absolutely have to destroy an original Parker cap jewel (tragic), because all of the available sticky/rubber gripping removers have failed, then it maybe better to slice it off from the outside then drill the stem out of the screw before fitting your new jewel.
Did you look on
Pentooling for cap tools/jewel removers? I bought a couple of different versions and they both work like a dream.
I've just spotted you are in Australia so maybe you can't get a delivery from Pentooling. Have you tried rubber gloves or a pencil eraser? Ideally you need something that is rubbery and very sticky.
