I might try your approach another time and see how far the belt would drift! I don't feel like taking those rods all the way out and back in again now! :-)Ivor O'Sheahttps://www.blogger.com/profile/10246251303703200543noreply@blogger.comtag:blogger.com,1999:blog-3491371204425376883.post-46109559262162143342011-11-27T18:26:45.232-08:002011-11-27T18:26:45.232-08:00That works, but I use a much simpler and more reli...That works, but I use a much simpler and more reliable solution... Ditch the guide altogether and just use two 608's side by side. You can see an example on my MendelMax at https://picasaweb.google.com/111347501166295022626/MendelMax#5671341423585469490<br /><br />The belt is 6mm wide, the pulleys side by side are 14mm, so plenty wide enough to keep the belt from wondering off. Yes, this adds an additional vitamin, but it is one you probably already have and if not they are only $.50 each, and this design is more reliable than printed parts in my experience.MaxBotshttps://www.blogger.com/profile/01800423038807169686noreply@blogger.com
