Grinder Adapter

This design is for a simple adapter to connect a Damo 5" dust shroud to a Craftsman 4" grinder. it is likely compatible with other grinders that have a 1.5" (common) mount. The Damo dust shield is available form Amazon, is the cheapest available, and is all metal construction, but it has an odd sized mount that fits no grinder I have ever seen.
The notch allows the clamp to compress the adapter to make a tight fit on the grinder as well as the dust shield.
