New core
This core was made out of a piece of alluminum bar, turn down to form a series of washers, bored and threaded down the center 1/2″ UNF, then threaded a bar with 1/2″ UNF thread, parted off plugs and screwed and thread locked where the washers on the core are, then drilled all the way through with a 6.5mm long series drill, then used a milling machine to cut slots inbetween the washers. This core could be made easily on a drill press instead of a milling machine. Instead of slots just perferate the centers between the washers. Made a shroad to go over it and an end cap to finish it off.
