I have 3 sets of wheels with Dunlop S/S rims, all built by my friend Roy, and none of which have given me any problems. Roy is now 91 and has been building superb wheels since 1937 during which time he must have built just about every combination of hub, spokes and rims possible. I asked him if he did anything different when building with stainless to when he builds with any other rims from that period and the answer was no. He did add however add that the tension on the old 32/40 and 36/36 combinations should be considerably less than the modern wheels with as few as 8 spokes. He also pointed out that the tension on all spokes needs to be even, but also bearing in mind that the tension on one side of a dished wheel will be less than the other. It is of course possible to build a perfectly round wheel, but with greater tension on one side of the circle than the other and that will lead to problems.
