That method is the way they recommend grinding tungsten...I recall something about less contamination that way. It works ok, but I'm sure you could screw up and flip one out. Not had a problem so far.Quote:

Everyone here wears a full face guard when sharpening, right? ;) Be careful out there. I really don't want to hear about anyone from this forum getting hurt. I'm done. Back to your regularly scheduled programming .....Quote:

bosch belt sander with trigger lock even better. sat perfectly flat when it was upside down. used that till i bought tungsten grinder.
tungsten grinding. it doesn't have to be, in most cases, so complicated. like one guy wrote; i used a rock. lol
Have you tried breaking 2% lanthanated ? The times I've tried, it splintered lengthwise.Quote:

Jerry's hardware didn't have what I want ...but ... red neck tungsten grinder ... ah ha ... I have a dremmel tool on a flex handle with speed control ... PERFECT! Thanks Rod ...you gave me a gr8 idea! I might change to a different tip but the idea is sound. Safe and effective ... I love it.Quote:

Thanks for sharing the red-neck tungsten grinder Rod (and if it gets contaminated, cheap to change to a new disk).Quote:

BOT, if you search there are other threads with PVC/grinder sharpeners.
Mark likes, and I liked Chem-sharp. I have not tried it since I went to lantanated electrodes. Will have to see if it works with them. Chem-sharp when you get the hang of it is nice compared to grinding. I used to sit and sharpen them all at one, thought it is quick to heat and dip while in the middle of a project.
Older threads on sharpening.

Always learning... Did a quick search... Ran across this... Chemically mills a perfect point on pure, thoriated or titanium type tungsten.Quote:

Man that's wild.. Wonder if you can take a handful of Tungsten's and sharpen them all at once with that methodQuote:

A few at a time might work via torch. The salts will harden and thicken around where you drop it in. So I doubt you can do a lot at a time. The jar is like 3" in diameter or pour it into something else. It does work.Quote:

Wow. That's a new one I haven't heard of. Pretty cool to watch. Given it's a chemical reaction, I guess it becomes less and less effective or clean as you use it and you need to use a fresh batch? Can you scoop out the undesirable bits like kitty litter?
I've heard of it ... been around for a while ... today I found a 100 grt 6" wheel mounted it and to my surprise it ran true and didn't need to be dressed ... I'll probably make a guide so when I dress my tungsten it will start to form a groove ... I'm all set for my new 200DX. ooo-rah.Quote:
