60W CO2 Laser cutter tube extension for SH-G350 machine

You can find complete how to upgrade article on my site: http://lensdigital.com/home/?p=1498
SH-G350 a.k.a. 50W Chinese Laser cutter from eBay comes with 800mm CO2 tube that fits nicely inside machine. However you can upgrade your tube to more power, but this means longer tube that will no longer fits inside. Fortunately machine has cover on the side that can be removed and longer laser fitted.
This enclosure easily fits 1250mm/ 49" SP 60W tube, with room to spare!
