While I'm not on 228, I'm 99.9% sure it's orange 1/4" urethane belting from McMaster. It's pretty fantastic stuff, see this thread. In the provided link, there's an in depth welding guide (by Art from 228), but essentially you melt the ends and smoosh them together in a piece of aluminum angle. Let it cool for five (ish) minutes, and you're ready to go!

Close. The loops are 3/16" orange urethane belting (McMaster-brand polycord), and the teeth on the bottom roller are 1/4".

The heat welded joints in the polycord are holding up just fine so far, although our full speed testing (2200 rpm) has been limited.
