Creating a Laser Circle in Your Drill Press - A Fun Project to Find Center Points. To start this project, gather the required parts: two AA battery holders from online marketplaces like eBay, one micro SPDT slide switch also available on eBay, and a 650nm 6mm 3V 5mW laser diode module that can be sourced from eBay as well. Using the gathered materials, assemble everything together by attaching m3x25 screws to hold in place the various components, then securing these fasteners using six m3 nuts for stability. Ensure the battery holders are securely held in position using two additional m3x10 screws to prevent any shifting or damage during use. Place this assembly into your drill press, positioning it accurately within its work area, allowing precise movements with minimal interference from other tools nearby, perfect for finding center points without hassle, giving users confidence while performing tasks such as locating holes or circle centers in metals and plastics.
