Using the Walthers 942 - 140 Turnout Drill Set is easy. First, identify which drill bit you need for the task at hand. For mounting Switch Machines to the benchwork, use the #43 bit. When working on the Switch Machine control rod, pick the #57 bit. The step drill is for panel mounting to match the diameter of controller pushbuttons and LED indicator bezels, and the 3/16' bit is for template piloting. When using the Walthers Layout Control System, make sure to connect the plug - and - play servo - style wiring properly. Since it's expandable, you can add more components as your layout grows. Be careful when handling the drills to avoid any injuries. After use, clean the drill bits to keep them in good condition. Store the set in a dry place to prevent rusting. And always refer to the user - friendly instructions that come with the items for detailed guidance.
