I†decided to make a CNC laser cutter with some material handling capabilities for my model plane project.</p><p style="margin-top: 0px; margin-right: 0px; margin-bottom: 10px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; font-weight: inherit; font-style: inherit; font-size: 14px; font-family: inherit; vertical-align: baseline; ">

I have some surgical tubing for the water jacket (the CO2 laser tube is water cooled). It seems to brown the water and I donít like that since it might accumulate some material in the water jacket. I realize I can clean the jacket with hydrochloric acid but I figure itís a better idea to not have any material going through the system.</p>

The laser itself has some nice white colored tubing on it to connect the various water jackets. Iím curious if anybody knows what it is so I can replace my surgical tubing with it.</p><p style="margin-top: 0px; margin-right: 0px; margin-bottom: 10px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; font-weight: inherit; font-style: inherit; font-size: 14px; font-family: inherit; vertical-align: baseline; ">
