Could you use the divisions on a $30 collet indexer to cut teeth in the circumference of the dividing plate? If so, and if the right pitch could be had, then a simple toothed belt drive on two of them might make a nice little glass lathe for cheap.
Does this sound practical, and what could be made up for ways?
