These are the pictures I took on 4-25-04 after completing the cleaning on my 1968 Cessna 210's corroded main carry-thru spar....Tags A12 & A22 were the worst spots since they were the closest to the edge of the spar...the thinnest part of the spar...A12 passed the measurement by .008 of an inch...it was by far the worst spot....although some of the other areas needed more attention, they were in areas that could stand extra metal removal.... I have since added the final pictures of the corrosion nightmare! The end results were very gratifiying!
