I’ve got one of those from NPU. It has Cillian O’Brien’s name stamped in it so I’m guessing he makes them for NPU?
This is an old Miller Falls #77 hand drill, I made the little wooden base - there was a wooden handle (shaped like a doorknob) attached to the bottom, I removed it and the shaft that the handle fit onto goes through a hole in the block. Two little bits of drill rod act as guides to keep the drill in place.
The drill was about $24 from some online seller.
I have one of those old drills, it works quite well, for drilling, I will have to give it a try for reed making.
