Default Extra Negativ which makes it Positive

Extra negative is the one that I got help from Steve to develop, which I use
to engrave text inside the rings
So now I can finally use Carbide to do this.
Also found another use for it, as I show in the video I have done.
please bear with my Swenglish :-)





Here I show how to grind with the extra Negative Temple

Start by marking the graver at 5/8 or 16mm


I start to grind the sides


At the mark you made, remember that stone height should be 3/4"


Grind equally on both sides so you can achieve (about) 0.005 "or 1,27mm


Then proceed to do the negative relief, point.


Take a little on each side at a time


Until you achieve this result


Turn it over and continue, being careful not to break the graver by pressing the wrong place


Grind until you achieve a thickness of 0.040"or 1mm


Then switch to the bigg temple, and start to grind the face


And end with making the heels of the length that suits you best.
I usually do my 0.006"or 0.15mm long


Finally, round off the little behind where you grind so it will not be sharp for the fingers

Hi Crazy Horse and SE,
Joacim emailed the photos and I placed them on the server. They should be working now.
Thanks again Joacim!

My first youtube video, hope you can stand my Swenglish :-)

It shows what you can use to engrave with it
Please experiment with the temple, so perhaps you will find something that is not I done.

Hi Joacim,

I would like to ask can one use Jocim's small template on 1/2" bench-stone height to taper the sides of gravers, if yes the template can put straight left and right side on the graver?

Hi Joacim
I have seen in the video it takes the corners off at 3/4" assuming it will do the same at 1/2" I have requested for one.

Hello Joacim, Thanks for this graver as I have begun experimenting with it and I like the control you get with it for inside rings. It takes a little getting used to because of being used to holding the graver in a higher angle but with a bit of practice it is another great tool in the arsenal.
Thanks again,
Rod

I do not quite understand what you mean SEngraver?
But you can not use the 1/2 height, to get the sides tapperd. it must be 3/4.
You will understand when you try.

Rodsta
I'm glad to hear that you like it. it offers many new opportunities.
But the most happy I am to have a Carbide graver that works for engraving inside the rings nowadays, this temple makes it possible.
