I have a Tormek T7 water cooled sharpening machine. There is a black silicon wheel available which will lightly sharpen tungsten carbide tools. Has any one used one for sharpening TIG tungstens? If so what were the results? The stones are large, 250mm dia and very expensive, circa £130, but...

As folk said above, grinder with a slitting or grinding disc, fit the tungsten in the cordless drill chuck and spin it on the grinder- it get rid of most contamination and leaves a pointy tip good enough for the work i do !

Ive always sharpened up a few at a time. Once they get a bit furred up or dulled, just swap over to another. Once theyve all been used, sharpen the lot again (i am a bit funny about liking them needle sharp, dont know why). In the workshop using a tungsten grinder, on site using a hand grinder...

Ok. Yes you are right if we are going to do it by the book, work to X-ray standards on highly critical stuff. In this case you would cut half inch off the tungsten and then grind them up. Personally I just grind them. The tiny amount of contamination I occasionally might pick up off my wheel...

interesting comments here, as I think its generally accepted that a separate grinding wheel is used to prevent contamination of the tungsten. My thinking would be that if you just grind the blob off, that would be contaminating the grinding wheel. thats the reason I cut the blob off rather than...

I use the same sort of disc, cheap on EvilBay, but clamped under the washer on one wheel of one of my bench grinders, does the job for sharpening, and have a chunk of steel with the right size holes, drop the tungsten in and whack the end... Dave H. (the other one)

You can get a soft wheel for grinding tungsten to fit bench grinders they work well for not a lot of money. At work we have proper tungsten grinders, in various forms, I think the discs are diamond in various forms.

I use a diamond coated grinding disk (for use with an angle grinder) in a drill and use a slitting saw holder to hold the grinding disk. and you can cut the end off the tungsten using the edge of the wheel

Same kit & settings, within minutes. Same on a second different brand m/c. If you’ve got two or three types to hand, say lanth, ceriated and zirc. Be interested to see if you get the same results. Will post a pic if I get a chance to do some test pieces next week. Got a DGP-3-v2 for...

gold/blue supposed to be safer than red, because red thoriated has a small radioactive risk if you breathe the grinding dust. We switched to gold/blue lanthanated because we were too tight to buy a grinder with an extraction system. But ultimately i don't think many people can attribute their...

I hear that Richard, and it sounds good to me. I do want to get the basics down solid. Right now, arc length and torch angle takes a lot of concentration. I want it be 'automatic' and effortless, AND comfortable. I am always struggling with positioning - me, the torch, the workpiece, the rod...

Yes iv tried a different tungsten

tungsten contamination? have you been sharpening them on a dirty wheel used for grinding other material? gas contamination? any leaks on the gas system drawing air in? have you tried a different tungsten?

Damn!!! that is nice!!! When you say a nice tight arc, do you mean pretty close to the work piece? i'm grinding my tungsten at 30deg roughly, nice and pointy. I do keep it really close... so close that sometimes I touch it hahaha, but thats because I back off the pedal. it's a hell of a tricky...

It's nice to hear from someone else trying to get to grips with Scratch start. I Think it will be a little while yet before I am actually sticking 2 bits of metal together with TIG. I started by sharpening a whole pack of 10 tungstens to try and get a bit more time welding. Next time I go to...

I too am trying to get a grip with scratch start tig but I spend more time grinding the tungsten than welding. Your efforts seem to be coming on well though.

I struggle with glasses with a welding mask - welding cap - hard hat. Summer - misting up (sweat) - winter (change of temp). Must get worse with an air fed mask and the face seal. I struggle more with keeping the Tig tungsten out of an ally weld pool. I have given up with ally welding...

If you've already got a bench grinder the diamond discs for a couple of Local Currency Units work well, take the nut and washer off and use them to clamp it to the side of the wheel, centre it up before you clamp up tight, Robert's one's parent's sibling. Then tungsten I'm the cordless drill...

high carbon steel can be used for lathe tools, as that is what they would have been used in the days before high speed steel, tungsten carbide and ceramics. the problem with high carbon steel is that you need to keep the cutting edge cool, so you can only use them with a cutting speed a fraction...
