Pickup Transmission Powers Nut And Bold Rethreader
The entire setup bolts to the top of a welding table in Knafelc's shop. He attached a big pulley to the transmission's clutch shaft and fitted an adjustable chuck to the output shaft, which holds taps and dies for cutting threads.
He puts the transmission in gear, then uses a pliers to force a nut over the thread cutter. To withdraw the nut he simply puts the transmission in reverse.
"It's fast and a lot easier than rethreading nuts and bolts by hand. It doesn't take long to rethread a whole bunch of nuts or bolts," says Knafelc. "I can rethread nuts ranging from 1/4 to 3/4 in. diameter. The big pulley gears the transmission way down so that it runs slow. I keep the transmission in second gear so the thread cutter rotates at about 60 revolutions per minute. I used a synchromesh transmission so that I can shift the thread cutter into reverse without having to stop the motor."
