Newby Tungston grinding

[john224]

Might be a silly NEWBY question,,
When grinding a tungston Does it have to be ground round to a point ? Could you grind it to a point but in a triangle/ square shape say 3or 4 sides
Its just ime having probbs regrinding my tungstones as they are only about 1,1/4" long as got 20-30 of these this size as i get them of a local factory that dont use them when they get to this size and i scrounge them off them,,,john

you could make a holder to hold them while grinding was thinking a tube with a clamp on top something like a scalpe tube

Could get yourself a pin vise, could probably get one cheaper elsewhere, but amazon was the first one google flagged up.

 

[madkayaker]

almost exactly what i was thinking

Yes they should be ground longitudanaly, this link should tell you prety much all you need to know:- http://www.diamondground.com/TungstenGuidebook2011.pdf

As for grinding small lengths of tingsten I just chuck up my tungsten in the flex drive of my Dremmel, or simelar small tool and runnit on a medium to slow pace holding it against a running belt sander or bench grinder, this or even in a small hand drill is quite a common practice.

MAKE SURE YOU READ UP ON THE DANGERS OF THORIATED TUNGSTEN AND ITS DUST PARTICULATES!

if you want some thing quicker to set up than the dermmel etc you could get a Stilo Tig

only use a belt or grinding wheel dedicated to tungsten only, to avoid contaminating the tungsten, if you want to produce quality work you have to go about it in a quality way!

Good luck

You have to ingest large amounts of Thoriated Tungsten to receive any possible negative results

If you can't use them, recycle them, scrap price might surprise you.

Put them in a rechargeable drill chuck and spin them slowly as they grind if you can't get hold of a pin vice as above.
