We used to use bits of scotch magic tape for shims on machinery back in the day. Cheap, durable and thin enough to give you control. Big benefit over sellotape being the relative lack of gummy stickum left on the machines.
Dean I have a DW705 mitre saw and need the inner and outer clamp washers for the blade where can I find these having trouble locating them or is there another set I can use 🙈
