aww page not found. i searched though. lets pretend not everyone on this forum has a lathe or a pillar drill. can it really be that hard to find a 150mm x 20mm diamond wheel with a 12.7mm bore for a bench grinder? im pretty sure the 25mm ones wont fit and i specifically bought the damn grinder...

The hole should be 22mm, most grinders are 12.7mm. Quite a few members on here use this method. Personally I still use an aluminium oxide wheel to grind my tungstens but it wears the wheel. Lot of advice on this thread. https://www.mig-welding.co.uk/forum/threads/tungsten-sharpening

yeah lets see, tomorrow there will be much tungsten sharpening as it took a swim a LOT today! god i hate green bench grinder wheels, le sigh

Either will work. I rough sharpen on an oxide wheel then polish the cone on an old CBN wheel which removes all the grinding marks and leaves it shiny. I'm not very good at TIG so the electrode gets dipped frequently. The biggest difference you'll find is the cost. Diamond wheels are available...

Thanks all. So, is CBN or Diamond better for sharpening tungsten? Or is there not much in it?

We're thinking to replace the stone on our bench grinder for CBN, it'll be used solely for sharpening the electrodes. Is 180 going to be too fine? Thanks, Chris

Thanks i just ordered one from amazon

It's best to use a sharpening stone dedicated to tungsten electrodes, as contamination can adversely affect TIG welds, so best get into good habits, especially for aerospace. I use a green grit (silicon carbide) wheel for the job, on a mandrel, in a battery or mains hand drill, set to high...

I had a soft green wheel for carbide and tungstens ate it for breakfast! For a bench grinder some sort of diamond wheel. I now use one of these - attach to a dremel - works well. I hold the tungsten in a battery drill to spin it around. A linisher with the right belt isn't bad either.

what do i need? fitting my 150mm grinder into the shed on the weekend, it only gets used for sharpening drills and now tungstens too so want to change the coarse wheel for a dedicated tungsten wheel

I was going to reply to this thread right back at the start, but decided against, that was not aimed at JOEPRO. but this is how do you sharpen your tungsten's on the bench grinder, ie on the side of the wheel, giving the wrong grain for the HF to help aid starting, or pointing up the wheel to...

ive had near missed with grinders, had a few grab and kick towards me and had a few things snatched out of my hands...when sharpening tungstens i have been chucking them in a drill so they arent in my hand, and ive been shrapening on the side of the wheel that is rotating away from me so atleast...

Not all from tungsten sharpening but I’d say I nicked fingers a hundred times with angle grinders minor minor stuff bit of tape on it and away you go and that’s happening from been to complacent. I caught my finger before sharpening a short tungsten in a bench grinder talk about pain never...

For me personally I like having a good grip on the tungsten during sharpening and a bench grinder feels quite controlled. Whilst I have 100s of hours experience using an angle grinder, for me personally I wouldn't want to sharpen a tungsten on one. If it caught or slipped you have a very sharp...

For most amateur TIG welders a bench grinder is just fine. What is your recommendation regarding a TIG grinder please?

Go on then - I’ll bite- how do you do it?

A bench grinder an absolute waste of time for sharpening tungstens, for a start any one doing any bit of tig welding at all outside of the workshop, won't be using that, and secondly, first thing I do is cut a tungsten in half because most welders use short backs, cause long backs break easily...

Try adding some filler to the autogenous aluminium runs to get more of a feel for it.
