In another thread on carving my own pipe someone asked about how I rusticated the pipe. I made a tool from a screwdriver bit and used a power driver with it. If you're interested you can read about it here Make a Rustication Tool
I've seen a couple of modified screwdriver rusticating tools but don't recall seeing one that was powered! I recently bought a small battery drill to use while putting up a small metal storage building, which has umpteen billions of screws. I figured it would just set until the battery crapped out but guess I'll add it to my pipe tool box! It has a size advantage over a Dremel in that larger bits can be used. Thanks Greg!
More than happy to give back a little to the community Ed, you and many others have been great helps to me.
And with the available of bits in so many sizes/shapes for a screwdriver and then being dirt cheap, it seems like the possiblities are endless with it!
