Laser Optics and Selecting the Proper Lens for your CO2 Application
Do you know what lens to use for your CO2 Laser Cutting application? In this video, I explain the differences in the lenses with varying focal lengths and why you would use them.

Step 30: Router Mount Part 1
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. The first of the videos for the router mount is finally edited and ready to post. The z-axis bearing supports were made in the current shape to be able to hold the router with a piece of stock in-between containing a hole for the router. This hole will need the ability to tighten against the router for stability and leveling. For my machine, I'm making one mount. This router mount will be positioned around the upper part of the router housing. Later, I will be installing a vacuum connection which will also serve as increased support for the router.

Step 33: Router Mount Part 4
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. This is the final step for the first phase of the router mount. I say first phase, because I will build a vacuum attachment that will also serve as an additional router mount. You will see the method at which I mount the router in this video. Instead of routing out a perfect circle, and we all know how good I am at routing out circles, and squeezing the circle around the router housing, the router mount will come in two parts and act like a vice. I did not want to put any undue stress on the wood by using the squeeze method, but it woks fine. I used it on my last machine and I had no problems and I even used only 1/2" thick MDF for the mount.
