Jig, yep, piece of cake.
The drill press has a drilling table with holes and slots. Get any piece of angle material, alum, steel or even make a up a wooden jig that can be bolted to the table and a stop fitted at some point, screwed glued whatever. Just press and hold the alum tube ito the corner of the jig and against the stop and you can turn them out all day.
Takes a wee bit of adjusting to begin with to get over centre and correct length. Use a Square and accurate micrometer\steel ruler and do a couple of test drills first to verify accuracy.
I use a 2" wide, 1" deep piece of aluminium channel withe a stud bolt which attaches it to the table and allows adjustment. Use the table slots and the table rotation to set it to the right position.
I'll do you a pic if you need of my system. The Serrurier owes it's existence to the jig and drill press. Best tool I ever bought, gets used constantly.
