> I've just made two drawbars for a 6x26 mill (not mine, I have an RF mill drill). I made them out of Ø12mm rod, one is M12 at both ends, the other is m12 at one end and 3/8 UNC at the other end. I put a flanged M12 nut on the top followed by an M12 domed (acorn) nut lightly tacked to the rod. Te acorn nut allows the end of the rod to be tapped with a suitable hammer/mallet to release the collets or other tooling from the spindle without damaging the rod. It also alows the drawbar to be screwed into or out of the tooling and the flanged nut is then used to pull up the tooling. The acorn nut and flanged nut allow two spanners to be used to fit and remove the drawbar without resorting to locking the spindle or hanging onto drive belts.
