I don't know the cost of gas in your part of the US, or how many miles to the gallon your vehicle gets, or the distance from a hardware store to your driveway, or the price of steel at your favorite metal supplier, or if you own the drill bits yet, or if you are running the drill press on Co-Op power, wind, solar or diesel generator, so you neglected to give me enough information to give you the total cost to make this tool, so I just did my best.
