Hi Y'all, I had a rotary tool (non dremel) with a flex shaft that came in a kit from Northern Tools. The flex shaft sheath burned in to. Northern does not offer any replacement parts and it would probably cost more than what I paid for the whole kit anyway. My question is does anyone use a flex shaft power carver and how does it hold up? Any advice for a decent carver at a decent price would be appreciated. I am not a carver by trade but do use them on my custom frames. Thanks. Steve
