TIG Electrode Grinding Attachment

thingiverse

This Dremel accessory simplifies tungsten electrode grinding for TIG welding. With 1/16", 3/32", and 1/8" electrode holes at four distinct angles, it utilizes a diamond disc (likely from Harbor Freight). Kudos to Lenbok (http://www.thingiverse.com/Lenbok) for the original design, which greatly inspired this adaptation. Print the model in your choice of sizes to fit 45mm grinding wheels. If necessary, enlarge the holes using a hot electrode or drill bit. Assemble by inserting diamond disc and arbor, placing them within the attachment's threaded end. Secure the arbor in the collet, attach it to your Dremel, and safely sharpen electrodes through designated holes, avoiding overheating that might melt plastic.
