New to the group I'm Chris higgins from oregon 41 winters old. I started graving this week. This is my current set up. Andu hand piece foot control with a sil air compressor(amazing quiet). Amazon ball vice and just built a power hone. No pictures yet. Waiting on more 3mm tungsten carbide rod to come so I can make more gravers. Made 4 today have to even this one out some and the heal was to big but this was my very first one I made.

welcome. looks like you're heading in the right direction as far as sharpening goes. good luck to you.

 

[mossleycrue]

Welcome Chris! You are off to a great start!

I was just looking at the heel. Try making the heel about 1/3 the length.

1/3 of what it is now

 

[mossleycrue]

Yes. Sorry I should have been more clear.

Your heel angle is deceptive as it is not running parallel to your face. It’s wider at the top as it goes away from the tip. What angles are you using I use a 15 degree heel usually with a 55 degree face.

I used the lindsay type system with a universal profile and 96degree face. They don't say what the heal is

I borrowed this image from Steve Lindsay's website.
This will give you an idea on what to strive for.

Also, when I first started to make gravers, I was using round HSS. I would grind the angles then add the heel.
Based upon a 96 degree graver....The 96 degree angle that I put the heel on was not quite 96 degrees. As a result the heel did not run parallel with the angle.
I had to go back and re-grind so that the angle was perfectly 96 degrees. I then added the heel.
I took me while to figure out what I was doing wrong.

I had to go back and re-grind so that the angle was perfectly 90 degrees. I then added the heel.

Ya I'm using round tungsten carbide and I see what you are saying. I have noticed with the templates you do have to go in a order and some are different. I'm going to see if I can adjust that one today

96 degree face ??? ugh. that's overkill by about 40 or so!!

[chrishiggins]

That's the set I used now I put them next to each other maybe that's why the heal is different

I think he meant to say 96 degree angle of the tip, not face.

No, this looks like the correct pair.
I had the same issue when I first started making gravers. I couldn't figure out why the heels were not running parallel with the angle. If I recall....I think I was using too much downward pressure when grinding the angles?? Try regrinding the 96 degree angle again using less pressure.

yeah. i later figgered it out all by my lonesome.
