I don't have a pillar drill. I think I could create a guide with a piece of steel tubing and a bit of plate. Then I could clamp the plate to the O/D casing, centre the tubing over the hole.. and that could keep the drill bit square on. That's my best idea so far. ![Er... what? o_O o_O](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
