Below I have put together a list of tools you will need when setting up your laser, running your laser, and at some point down the road, troubleshooting your laser.
Tape Measure. For measuring, I love this Soft Tape Measure. It's designed for sewing, but makes it easier to measure things that are round.
Laser Safety Eyewear. The acrylic lids on the lasers do not have any certifications. You only have one set of eyes, so why take risks? Below are several options for Laser Safety Goggles.
Fire Extinguisher. Fires can get out of control very quickly, so you should always have a fire extinguisher nearby. CO2 Fire Extinguishers are more expensive than typical home fire extinguishers, but the also don't produce the mess, which makes them a better choice for putting on laser fires. They are also safer than halon type fire extinguishers. Order the Amerex 5LB Carbon Dioxide Fire Extinguisher on Amazon.
Magnets. If you have a piece of material that won't lay flat, try these 95LB Rare Earth Magnets or 100LB Neodymium Magnets. I prefer the 95LB magnets because of their low profile. (Please note that you will need to have a steel or iron bed for these to work.)
Digital Micrometer. Useful for measuring mirrors and lenses: Digital Micrometer.
GFCI Receptacle Tester. Used to determine is an outlet is wired correctly: Receptacle Tester.
Digital Multimeter. A must have tool for a laser owner: Digital Multimeter.
Soldering Iron. Another core tool for the laser order, Soldering Iron Kit.
Square. Useful to plumb the laser head to the bed, 7-Inch Square.
Torpedo Level. Used to level the laser, Torpedo Level.
Digital Torpedo Level. Same as a Torpedo Level, but with a digital display, Digital Torpedo Level.
Digital Angle Gauge. Useful when aligning objects on a rotary, Digital Angle Gauge.
Electric Drill. Used during installation of ammeter and exhaust fan hood, Electric Drill.
