Cordless drill upgrade for about $40

Step 2 Disassembly and modification

The first thing to do is to remove the screws on the drill, then take notes on the inner workings, this is important because you might not have the same drill. Remove the batteries because they might be leaking corrosive or toxic chemicals so take them to a poison control office or hardware store where there should be a bin for old batteries. Next remove the gear from the motor and leave the switches intact because they will be used later. Then finally cut away from the base because you will need to make space for 1 battery and the connectors. Now you have all the salvaged parts.
