I have never done a aftermarket speedo but on the stock ones you have to (carefully)pull the pin. Rotate the numbers where you want and put it back in. Most of them have 1 full tooth then 1/2 tooth. It will go one ever other one. It will make sense when you look at it.
If the drill would spin it at 100MPH (I would bet it would be closer to 30MPH) It would take about 100 hours.
