Mirror Alignment Tool for Co2 Laser Cutter and Engraving Machine

Better explanation needed on web site in measuring lenses to select correct RLA tool to fit my laser.

This tool is a must for every Laser user that thinks that he has perfectly aligned his machine ! I was one of them but when i installed the device and followed the instructions i realized that i was working 2 years with my laser with 70% power and not 100% because of the misalgned mirrors ! 100% suggested to buy.

It works well but the parts separated

It works well, but the brass and aluminum pieces came apart the dirt time I used it. I pressed it back together enough to complete the align, but it looks like there should be some sort of adhesive that should hold it together.
