2 inch wide grinder wheels
thingiverse
I'm currently working on a 2x72 belt grinder using scrap motors and 3D printed parts for blacksmithing projects. I'm experimenting with ABS and PLA prints, but I'm unsure if the wheel treads will handle heat from the process. The bearings are 5/16 x 5/8 x 1/4 flanged, salvaged from equipment I used to maintain. Update: After a long break, I finally returned to building a grinder for these parts. I've successfully re-profiled and sharpened a knife blade using the wheels! The drive wheel has some added tape for tracking, which will be incorporated into future prints. My crowned tracking wheel wasn't enough to compensate for my initial mistakes. I'm sharing videos of this project online, check out [78mkefLvthk](https://www.youtube.com/embed/78mkefLvthk) and [oXi8zgDqfkA](https://www.youtube.com/embed/oXi8zgDqfkA) to see it in action.
