Toolpost Grinder Wheel Guard by clough42

Last crawled date: 3 years, 1 month ago

This is a two-piece wheel guard for a lathe toolpost grinder I'm building.
SAFETY WARNING
This is a safety device. If you choose to make one, you are doing so at your own risk. Be sure the materials and fabrication techniques you are using have the necessary strength for this application. A grinding wheel can fail and burst with considerable force and cause serious injuries and even death. The purpose of the wheel guard is to absorb the energy of a wheel failure, protecting the machine operator.
Many common 3D printing materials and processes are not strong enough for this application.
Always wear eye/face protection when using any machine tool.
Assembly
The cover is attached to the guard with five (5) 8-32 button-head screws. The 8-32 threads are modeled directly into the STL files, but may require cleaning up with a tap, depending on your fabrication method.
The guard is attached to the body of the grinder with 1/4-28 button head screws and washers and 1/2" diameter standoff spacers. Be sure the supporting structure is able to withstand the impact of a wheel failure.
