Raggedy Man Posted February 14, 2016 Share Posted February 14, 2016 I am looking to upgrade from my dissection probe to a pin vise for prepping. I've had no problems with finding a suitable pin vise, but they seem to come with drill bit heads and not needles. Specifically, I'm looking for the tungsten-carbide needles. If anyone has a source and would share it, I would greatly appreciate your help. Thanks in advance! Best regards, Paul ...I'm back. Link to comment Share on other sites More sharing options...

Auspex Posted February 14, 2016 Share Posted February 14, 2016 Try searching under "scribe".

Raggedy Man Posted February 14, 2016 Author Share Posted February 14, 2016 Thanks Squali and Auspex! This will definitely be easier than sharpening my probes after once a week. Best regards, Paul ...I'm back. Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 14, 2016 Share Posted February 14, 2016 Paul, I've gotten scribers from HERE before. There are carbide replacement tips available, but they are more expensive. Hope this helps. Regards, Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

jpc Posted February 15, 2016 Share Posted February 15, 2016 This has been my source for the past 20 years. http://www.mscdirect.com/browse/tn/Raw-Materials/Metals/Carbide-Blanks/Carbide-Rounds?navid=12102067&rdrct=carbide+rod Comes in different thicknesses so you have to make sure to get the right thickness (diameter) for your pin vise. Most pin vises come with four different chucks. You need a diamond wheel on a Dremel to cut and sharpen the carbide rod, and for microscopic stuff I use 200 grit diamond sharpening tools as well.

I've been doing the same. Carbide rod works well. Make sure you don't apply any lateral force when pressing or you will snap the smaller diameter varieties. I also use a sewing needle for fine work. I know what you're saying... too soft. I grind it to the required shape (kind of a rounded chisel) and then heat it with a torch and quench in water to harden it.

jpc Posted February 15, 2016 Share Posted February 15, 2016 I have used sewing pins for soft matrix, and they work very well as well. But for harder matrix... carbide rods. Link to comment Share on other sites More sharing options...
