Why don’t you put a pressure gauge on the machine to tell me how much pressure is against the reel?

There is no practical way to measure the pressure between the drive rollers and the reel flanges. A pressure gauge on the power unit cylinder is susceptible to false readings and therefore can become a safety problem. Any readings at the cylinder or extrapolations of such readings would vary from pull to pull depending on the cleanliness of the slide rails, the lubrication to the rails, the internal integrity of the cylinder and other factors that make it totally unreliable. The best way to determine the pressure is ratio of the drive roller material against the flanges.
