7.48mm Valve shim sanding tool

thingiverse

I designed this to hold a 7.48mm valve shim centred so that I could sand it on a surface plate. I am only doing this because there isn't a local shop that stocks the shims I require—keep in mind that sanding may affect the hardened surface of the shim. This tool is designed to maintain concentricity and parallelism between the two faces of the shims. If you use this tool and blow up your motorcycle engine due to improper shim sanding, then that's on you.
