I only ask because most commercial ceramic rods are way too fine for what I do.
Wow great question!
Well, on THAT scale, hmmm... I would have to rate these things as 'Infantecimal' !!!
I'm almost positive that is a word, although I think this is the first time in my life I get to actually use it haha!
...Smooth as silk!...
But yeah these ceramic tubes are truely the bees knees when it comes to hardness!
....As I was 'grinding' the tungsten filament stubs off
and attempting to put a 'beveled edge' onto the ceramic tube ends with a bench grinder
the filaments AND The ceramic both glowed red hot!!!
And I would have put a major hurting on that grinding wheel had I not continuously
kept the ceramic cylindrical end in motion, parallel to the grinding FACE of the wheel
( think of this as aiming at the center of the Earth,
with the 'Earth' being the grinding wheel,
you'll want to aim the barrel of your ceramic cylinder
directly at the 'center point of spin' on that wheel! )
...while simultaneously twisting the ceramic rod trying to maintain a constant, steady, 'feed' of the ceramic from left to right across the wheel so you dont dig ruts into your humble, hard working grinding wheel !
This ceramic stuff is hard to manipulate but with time and patience you will see the results!
Then those beveled edges will be as smooth as silk and you'll have birthed onto this planet a shiny new tool to pass down to others you'd like to see maintain thier sharp edge!
What could be better than that?
