eBay Chinese CO2 Laser Cutter & Engraver Exhaust Duct Modification Part 2

In this episode we will finish up the modification to the eBay Chinese CO2 Laser Cutter & Engraver Exhaust Duct which will provide extra bed space to the eBay Chinese CO2 Laser Cutter & Engraver that was wasted before.  We will also make the duct air tight to improve the air flow out of the unit and use a shop vac as means to evacuate the fumes via 1.5 inch flex able hose to the outside.

While you might question the 1.5″ hose verses that of the 4″ you typically see,yet because of the draw of the vacuum this works well as I even have to leave the front cover open a bit to allow enough air in!  The noise Because of the shop vac is a bit loud however no louder than when I use my CNC machine.  In a future project I may try modifying some of this, however for now it works well and have other modifications we plan on making.
