"Tool post grinder" as in, not a tool post grinder, but I don't know what to call it. "Tool post DIE grinder?" It ain't even that. It's not a die grinder and it doesn't even go on the tool post. If anyone knows what to call this, let me know.
I've been meaning to make this for a long time, finally encountered a project that required it, so I whipped this up quick.
It's a "rotozip" which is half way between a dremel and a die grinder in terms of power. Spins high speed, and has collets for dremel-sized bits as well as 1/4" shank die grinder bits. I think it spins as fast as either. It's meant for side-cutting like a router so I expect (hope) it will have more axial fortitude than a dremel does.
I reupropsed the aluminum arm from a worn out German bagging machine at work. Cut it to size with the bandsaw and finished the surfaces in the 4-jaw. It already had that hole with split clamp but I enlarged it.
I cut the notch out of the bottom to get the existing hole as close to center as possible, then mounted the arm to the compound, then put a boring bar in the chuck to enlarge the hole, that way it's dead on center as soon as I mount it, no adjustment needed. I used a unistrut nut as the t-nut for it.
