I still have the original square-section rubber belt in use on my Ariston RD11S! An occasional wipe with ArmorAll has kept it looking and performing as new! I've had it since the Carter administration!
What Type Belt Are You Using
So which type of belt are you using on you TT? I am just curious as to what others use on their rigs? I am using a 1/2" Mylar belt on my Redpoint Model D... I make them myself from a roll of Mylar Streamers which is about to be gone, so I am sorta looking around for a replacement for the stuff I am using???
