This is an outdated version: see this post about stainless steel shims
Finally got around to figuring out how to bend my own steel shims for my table saw. I had read on some forum where many have had success using brass shim stock from their local hardware store. I thought that this was a brilliant idea but I thought that the brass stock would be too malleable and not allow for proper arbor alignment as the set screws would wear through fairly quickly.
I first created a jig where I could maximize material usage by allowing me to precisely cut stock to the final length of the shim, then to be able to cut the strips to the exact overall width of the shim so that it could be bent exactly to the dimensions needed. I think the pictures below are self explanatory.
