I have a post that is in need of a washer, and unfortuneately, the bolts used were some other measurement, as they are like 1.1 inches or something. THey are a fraction too large for the 1" washer. I can almost screw on the washer, but since it isn't threaded, it it won't fit. I was thinking of dremeling the center to make it a little larger, but since the thing is SS, I am not sure what grinding tip to get. THe home depot guy just pointed out stuff to cut it, but I ust want to grind a little off the inner side. Any ideas?
