Sink grinder

Last December I realized that I need to up my game.

I have always been unsatisfied with the final finish of the etching process I use. I’ve spent hours and hours at the sink with various wet abrasives and despite how long I scrubbed I was never quite satisfied with the results. Furthermore, I have a long term goal to incorporate more champlevĂ© into my work. I’ve ground enough glass (very little) to know that power assist for that task would be the bees knees.

So I stared looking around for a powered grinder of some sort that was versatile and large enough for me needs and finally happened upon the Single Arbor Grinder (SAG-1) made by Denver Glass Machinery pictured below. It would be the perfect solution if I had a much larger workspace and a few grand of extra dollars.

The Single Arbor Grinder made by Denver Glass Machinery sells for $2300.

Then, I found this image showing the guts of the SAG-1 at the forum. A motor, two pillow blocks and a shaft? Is that all? I can build that.

I’m calling my design a Sink Grinder because there is where it will reside. The frame and motor will both be attached to the wall and easily removable. I’ve drawn three versions of this machine in Inventor so I think I’m ready to build the first prototype. Hopefully this one works so well that I don’t need to build a second.

Th last of the parts are on order, the shaft has been machined, and the frame is fabricated. All that’s left is assembly, and paint. Then the grinding can begin.
