2D spiral to unfoldable Sheet metal

I have the need to make a spiral like a watch spring (not a helix). The sheet metal tools don't work on the spiral sketch but I can do an extrude thin feature to get a model that looks like sheet metal. The add bend command does not work on the result. This wouldn't be a problem as I could just manually draw a flat pattern for manufacturing except I need tabs on the edge of the spiral that will interlock into slots on a plate that the spiral will weld to. I know I could manually figure out where the tabs and slots would need to be but it really seems like there should be a better way.. Any ideas?
