Marcelo. you should only need to cut as deep as you can comfortably cut a straight line by hand at first ,Depth will come later after you have better control of your tools. Try to turn the work into the tool and hold resistance with your tool hand. In reality most of your power will come from the hand that you turn the ball with. Yes you will create resistance with the tool hand and that is what develops CONTROL. Good luck and keep cutting!!!!!!
I realized that the graver behavior with different heel and parallel with conventional heel. I do not know if this distinct behavior only occurs in the hand push. The lower curves, with the parallel heel, not look nice in my hands startup. There is difference in the outcome when using hand or push air graver?
Thanks a lot.
Thanks a lot.

A poorly shaped graver will act just as bad in a power assist as in your hand. You have to make minor adjustment that fit YOU, The length and angle of the heels are ones that seem to matter the most in hand powered engraving.
i have not tried it yet. sam posted geometry for hand push, whereby the face is 10 degrees off axis. this should help with your problem.the side doing the cutting is slightly forward of the other, thus tending to reduce the problem. check it out. let us know if it works for you.
well- first things first. your scrolls are really pretty consistent in the execution. a couple are a bit off, but not too bad. i think with not too much in the way of practice, you will get to where you want to be. i don't see too much "chatter" on the sides here, but maybe my eyes don't see it. what size is this plate ? as the scrolls get smaller, you'll find your problem will likely become larger. it all takes time, but will come to those who stay with it.
Your cutting looks good. I'd say the graver is doing well for you.
I can't explain it other than long heels are preferable for hand pushing. An exception would be light shading lines that are mostly straight or slightly curved. For those I used a standard heel square graver with a low face and low heel angle. It was not, however, suitable for engraving scrolls. I also cut a lot of shading in hard metals and on curved surfaces with hammer & chisel, but would use a hand graver when possible.
One of the most beautiful works I've seen, well cut, clean lines and defined, let alone the shading. I think all they do engrave dream one day do something like you. Could you tell what tools used in this video. "Fine shading". thank you .
Thanks Marcelo
The graver I used in my shading demonstration video is a standard heel (not parallel) 120° graver with a 45° face and 15° heel. Nothing special. Just the same general purpose graver I've used for many years.
