Default Negative Relief Template

Below photo is from one of the original patent drawings that is at the bottom of the sharpener instructions page. It shows this type of point well. http://www.engravingschool.com/priva...0Sharpener.htm



Negative relief 116 Uniform-Parallel graver template.

This template is the same as the normal 116, but the relief grind under the heel is negative. The purpose of this negative grind is to achieve more heel clearance. This additional relief was described in the
Lindsay Uniform-Parallel patent, but this is the first template made available to actually achieve this point.

This template requires that the height of the grinding lap or bench stone be 3/4" instead of the usual 1/2" seen in all previous templates. I recommend just shimming your 1/2" stones up the last 1/4". The plastic 6"x6" plate included with the full sharpening kit happens to be 1/4", so that can utilized.

A power hone for initially shaping this is helpful. However it can be done with the diamond bench stones. Steve tested how long it would take him to sharpen one from a carbalt blank on the diamond bench stones. It was 15 minutes. Of course starting with a the 3 degree tapered carbalt blank would considerably shorten the time.
$27.00


At requests of Joacim Jansson and jimbojeweller below is another Negative relief template. This one is using the 96 degree detailing point. Above iis my post a year ago about the first negative template using the 116 universal point.

Here is a photo of the Negative Relief Detailing 96 degree template and add to cart button for it:
$27.00
(This one also uses a 3/4" stone height as described above. It comes with a 1/4" shim to go under your 1/2" diamond bench stone)

When I started to grind it up, I thought that perhaps it would need even more space behind the heel.
But after I tried to engrave inside a ring, I could say that I come further with this than my old freehand grinded graver.
To access better, I have sanded down the sides so it is about 1.2mm thick.
So one can say that now there is finally a graver, ready to be used for engraving inside rings
Thanks again Steve!
you make our life easier and more fun
