Laser Shaft-Alignment Authenticator

thingiverse

If you need to precisely align one shaft with another that is some distance away, this tool is a great solution. It makes use of a $20 off-the-shelf laser from Amazon: http://amzn.to/1g4Jx9C. Additionally, it requires a regular CR2032 battery for power: http://amzn.to/1UBTjO0 (note: the link is an affiliate). To assemble, secure it to your shaft using bolts and tape down the bare wire leads from the battery in place, followed by inserting the battery from the top into its slot, after which you'll add the laser module. The hole is exactly sized for the laser so it fits securely without any gaps or loose spots. Once the tape comes off the laser will be on permanently at this point. Next, carefully rotate your shaft while allowing the beam to hit a distant surface twenty feet away and beyond. Note that as you turn your shaft if the laser hits either side of a small circle instead of one exact spot loosen and tighten some bolts attached above using this specific bolt pattern. This procedure lets you calibrate just how well adjusted the device should be with regard accuracy in its performance capabilities on various levels throughout time when applied under optimal operating conditions within real-world scenarios where high precision matters above everything else - which often proves true across industrial manufacturing settings amongst many industries today that value efficiency highly indeed;
