same video I just watched. Out of curisoty of how it would be done. Looks easer with a drill press but I would probably drill a hole in a bottle cap for my 510 thread to sit in than hold a thin piece of wood (or something else soft),over the centre pin than very gently tap it out with a small tack hammer. Guss once it got started it would pull out from the bottom easier.
