After so many posts about cleaning/restoring these hubs I decided to clean mine up. Scotch brite abrasive wheel and 400 grit paper and it was looking pretty good. I got some new locking tabs from Walcks. Nicely made stainless steel but they are pretty thick. In fact so thick that when bent over to lock on the flat they stick out proud of the edge surface of the hub as you can see in the picture. With six tabs sticking out higher than the edge of the hub it makes fitting the wheel rim over the hub pretty difficult. I was able to finally do it but after chewing up my newly polished hubs. Has anyone had this difficulty? I had some of Herms which are thinner but the wrong shape. This is going to make tire changing in the field much more difficult. Thanks.
