Knee pads are smart. I have pointers for my Brothers. Angle the Capstan so the MTape feeds onto the edge and wont lap itself. Wrap only enough times to finger pull and control the stop and go (gradual start) So when the hand puller guy stops pulling, the MTape slips on the wheel and stops pulling. About 3-5 wraps adjust/ add wraps to maintain finger control. The 1st MTape puller must have the radio speaker by his ear.
