I'm also curious for input from those that already have some of the portables.
I currently use a 6" diamond flat wheel on a bench grinder
I like the concept, but other than the above mentioned Milwaukee, in listening to the reviews, the motors sound like they're ready to implode
I was looking at getting one of the sharpeners until I saw the prices!
I’m going to keep doing what I’ve done for years, using a cordless drill spinning the tungsten against the diamond wheel on the bench grinder……I do a bunch at a time, both ends, keep them in their case to keep them sorted!
I was thinking about making a guide for the different angles, that’s one of those projects that I’ll get to one day?
yes the cordless drill makes a big difference especially when cleaning up a buggered hot tungsten.
I've actually thought about keeping one of my "retired" corded drills next to the grinder
Using a "flat" wheel I can't cut off a section of he electrode, using a standard al ox wheel to rough it to clean
If you are dipping enough to need a hand held one then you need to stop, and go back to practicing...
A great portable option is a small harbor freight grinder and buy a 3" diamond plated wheel for it. You will need a clamp to hold it down, and a drill to spin the tungsten concentrically. I only sharpen mine to a bullet point, and polish it after grinding on the diamond side. I do this for all materials, and will go more pointy or blunt depending on the arc I want. Works both on inverters and transformers, but will need a ball end for AC transformer machines.
