Shop Infrastructure: Flex Shaft Grinder

The months are ticking by at an astounding clip, so I figured it was time to tackle a small infrastructure project in the shop over the weekend. For Christmas, I got Kaylin a flexible shaft grinder from Harbor Freight. When she’s working in her studio she often needs something a bit more aggressive than a diamond file or sandpaper and the grinder is the perfect tool.

After discussing, we decided that it made the most sense to keep the dust in the workshop instead of trying to create a setup in her much cleaner studio. The grinder will also be useful for post-processing 3D printed parts, so I will benefit from having it in the shop as well.

The grinder itself has a direct drive spindle and a motor designed to be hung above the work area. Instead of hanging the motor, I designed and printed a wall mount and a holder for the hand piece so everything could be mounted for quick access. All the cable organizers are also quick 3D printed parts.

So far this is incredibly convenient to have in reach right above the bench. I might adjust where things are mounted over time if it’s not working as expected. As a final enhancement, I am designing a holder for all the the rotary tools and bits that will get mounted for easy access.
