The "drill-press" trick for removing screws

Found this by accident on another forum: "Yamaha XS1100 and XJ1100 Carburetor Restoration Services". So it seems I can't take credit for this idea after-all. Pretty naive to think someone else wouldn't have thought of this a long time ago and apparently they did. Clever use of the tilting table as well but I'd sure as heck not leave the carbs unattended like that !
