This is a complete set of bushings precisely machined to match the diameters of your pen hardware kit. The bushings let you easily gauge the progress of your turning, allowing you to achieve the smooth, perfectly flush seams so valued in a top-quality hand-turned writing instrument. Just turn the blank until the ends are almost flush with the bushings, then sand to final dimension. Made of steel-hard enough for excellent durability, yet soft enough to prevent damage to your turning toolsTip: when turning light-colored woods, apply a bit of CA glue to the bushings to prevent metal dust from migrating onto the turning blank
I'm surprised of colors Bushings for Over/Under Shotgun Pen Kits. Looks different than on image!
