I have been using fender washers ever since I started making bears about 18 years ago. They come in various sizes and I have never had a problem getting a size I needed. I used to use the little washers with them the way you do when using fiberboard disks, but then I read somewhere that the little washers were used to protect the disks from wearing down and, as they are also metal, I realized that I didn't need to use them. I have not used them for several years now and have not had any problems with my joints.
