I have been collecting some older Pacific C presses through the years, and wonder if anybody knows of a source for those straight bicycle-like handle grips for the 5/8" diameter operating handle rods common to these old presses. They don't have any finger grooves in them. And also, on a similar theme, does anybody have suggestions what might work to keep these plastic/rubber handle covers on the 5/8" rod so they don't slip off or turn during use of the press?
