What I want to do is make holder that I can mount my Dremel 300 to. I can't figure out if there is a tap out there for this or another method I've not discovered for threading this. The threading I'm referring to is at the tip of the housing, near the chuck. When the finger stop tip of the housing is unscrewed there is male threaded end beneath the it . It's this portion I want to screw in to the holder I'd like to make. If there are web links or suppliers for a special tap please let me in on it. Thanks and Take Care ~ Rich
