How to make pneumatic engraving machine from a mechanical center punch.

In this video I show how I make a pneumatic engraving machine. I made this engraving machine for informational purposes only. I've always wanted to try engraving metal with a pneumatic graver. But this tool is expensive. Buying it just to try it is not a cheap pleasure. Therefore, I decided to make a pneumatic grader myself. To do this, I purchased a mechanical center punch for $ 4. I used the automatic center punch as the basis for the body of the pneumatic engraver. Conclusion: such a tool cannot be used for serious metal engraving work. But it is suitable for informational purposes, in order to simply understand the very principle of operation of a pneumatic engraver. And satisfy your own curiosity. I wish you a pleasant viewing.
