Has anyone tried longer belts and a 2nd idler for the high speed belt? My belts, 800mm (31.5") & 686mm, (27.0") are so tight that I need tire levers to move them from pulley to pulley. They snap into place with a loud BANG! At least I doubt they will slip 1/2" longer belts are available, which should make changing them much easier. I've seen Fabrikator's quick change setup, with one relocated idler. http://www.projectsinmetal.com/forum/general-discussion/diary-of-a-new-g0602/ If it didn't work well, he wouldn't have posted it. But I'm somewhat OCD about stuff like this and feel idlers should always be pushing inward for more belt to pulley contact. And that they should be on the return run, not the tensioned side. I have all the materials I'd need to build such an idler on hand, including suitable bearings. It seems like a good 2nd project, after a reverse tumbler.
