Lenawee Co Michigan | The center shaft has to be dead straight. It takes very little to spring them. A small kink, almost unseen will make them clatter.
I've seen them straightened sucessfully. There's a fellow in a factory I was at in Ohio who had a jig made up to spin most any size auger and by close observation (or the auger stopping in the same place each spin) would give it a tap in the right place and after a few attempts would have it running perfectly true. It's an art like swedging sawmill teeth. |

Sac & Story county IA | Think "equal and opposite". Weld an inch, turn 180 degrees and do the same. Do that about every 2 feet. It is the nature of a round tube auger to center itself in the load. Don't sweat it. If it is run empty, it is going to bang and clatter. Some worse than others. |

Central NY | MOUNTING: For years many manufactures would tell people that they could not replace flighting on their equipment, because of stretching and special mounting practices only available at their factories.
Before modern flight rolling equipment was available, this was true,' tolerances were quite loose and flights were stretched when mounted in order to bring the inside diameter down to meet the pipe or tube. R.F.S. produces flighting on the most modern and accurate flight rolling machines in the world, as a result the flights slide onto your center tube with a minimum of clearance (be sure to remove the old flights). In order to allow the shaft to slide onto the tube there must be some clearance. The recognized standard is -0, + the material thickness. R.F.S flights are generally closer than this. It is recommended that you simply wedge a pin or a nail in between the flight and the tube in order to place the tube in the center of the flight hole, this keeps the flight from shaking when rotating. If you wish to stretch the flight down this can be done by welding one end of the flight to the tube and attaching a fence puller or come-along to the other end and pushing against the center tube while pulling on the flight. When welding the flighting back on your tube simply tack weld every 12" or 18" (use the old weld pattern as a guide). Be sure to rotate the weld spots around the shaft so they are not all on one side. Overwelding or welding on one side can cause the tube to warp.

South Dakota | I get all my flighting from them and is all MUST be stretched. If you feel movement of the flighting on the shaft if is not tight enough. To stretch the flight weld one end to the shaft then weld the other end of the flighting to a channel that is the length of your auger and take a pipe wrench and turn the shaft and have someone hit the flighting all the way from the end that is welded to the shaft to the end welded to the channel on a 10' length you should get 3/4 to 1 flight of stretch. |
