I would look at the blade hegith and feed angle. Would seriously doubt its the reg wheel loading up. If angle isnt correct there isnt correct point of contact and that may allow slipping.
Does anyone know what could cause "straight-line" pitting during chromium plating.? The parts have pits in a straight line on the top and bottom in a horizontal plating bath. Happens on both previously plated and not pre plated parts. Chemistry check ok i.e. Cr,sulfates etc.
