I enjoy watching the Oxtoolco videos - it's like being able to look over the shoulder of a talented machinist. He's a talented guy who's willing to share what he knows for free - hard to argue with that. About the spring tool holder: This was new and intersting to me (a newbie, remember). After watching the video, I did a bit of web searching to see if I could find more information, but came up blank. Does anyone know if these have another/different name?
