Does anyone know the type and size of, and maybe a source other than Graves for a belt for a late 1980s or later model Graves MKIV faceting machine? I picked up a MKIV machine recently that has the large 6″ plastic v-pulley on the lap arbor but no belt. And it has been so long since I’ve had one of those model Graves machines that I don’t remember the type of belt that they use. I had thought it was a 2L type belt. I ordered a 2L280 belt last week from an industrial supplier which I received yesterday. But the 2L belt doesn’t appear to fit the v-groove in the 6″ plastic pulley very well. I’m hoping to find a source other than Graves for a belt due to having heard and read of several incidents of customers complaining that over the last several months it has become very difficult to get orders filled and shipped from Graves. So any help here would be appreciated.
