Speed Queen dryer drum

[Thorning]

I have been given an older Speed Queen gas dryer with model number HG6009L for repair. The repair was minor but the drum has the typical problem on a lot of older units of this type in that the drum has a bump at the seam where the support rollers or front support glide strips ride. This is evident when the drum  rotates with a thump thump thump noise. I mentioned this in a previous entry a few months ago  but got very little response .I have not done anything to revise it but am requesting other techs to comment on the subject. I have considered using some BONDO type filler to fill in the area but dont believe the material would stay in place. Another possible idea is to put a steel strip about 4 inches long in place over the seam using my MIG welder and tacking it  and then smoothing any rough edges. This would be a little tricky to do with any success. Comments are invited

Today I took apart a newer Speed Queen gas dryer which was about 3 years old. It was very clean and ran well but had the same problem as I noted  earlier. The seam of the drum has a slight dimple at the weld joint which makes the very slight noise when it passes over the rollers. This is a negative  item in an otherwise excellent design dryer that will last for many many years. Has anyone tried to correct this problem ?
