Tungsten sharpeners for TIG welding are a dremel motor w/ a pseudo-fancy pencil sharpener on top. They’re great, they work well, fast/easy all that. But do a quick comparison between one of those, and a regular dremel motor. It is insane how expensive a “tungsten sharpener” is.
I found some designs on the internet, but they weren’t very good, so I started from scratch and solved all the problems of those other designs.
The lower part of my design, w/ a couple of pieces of tungsten, sets the correct height for the diamond grinding wheel.
It has 3 locations, each w/ 3 angles to sharpen…because sharpening tungsten for just a bit too long gets it hot enough to melt the 3D print. Be quick about it and it’s fine, but do it for too long = melt.
30-45-60deg angles, including a slot to cut off a blobbed tip, and a hole in the top for flat tip end (if you are so inclined).
Fits typical dremel motor w/ a slot for ample room to tighten the collet nut.
This certainly isn’t as fancy as expensive sharpeners, but it works great.
