w/c Illinois | After I get a section all welded up I take a four foot level and check the entire length looking for high spots that will wear the tube. Check at 12, 3, 6 and 9 o’clock. Move down a couple of feet and check again. I grind off the high spots as I figure they will wear off anyway and likely put a hole in the tube. You’ll be surprised how uneven the flighting will be. When you order the replacement flighting, get extra. The first and last foot of each section is often mis-formed as the material enters and leaves the roller die. | |
