Title: Small compressed air driven chisel or hammer ?????
Post by: ksor on January 10, 2014, 04:35:00 PM

I remember such a project and I think it was in here - some years back.

Small like a pencil and driven by compressed air.

I remember the picture of the man who made it - a portrait - (because he looked like my borther in law) - a very gently looking man, Black/gray hair, a wonderful smile

I've searched with no Lock - now I'm looking through Darren's postings - because I think that was the name (but there is no picture there today.

Help please !

I have a small hand held air operated percussive engraver it 'sort of' fits your description. It is equipped with a tungsten point and I use it (occasionally) to mark tools etc. I'll dig it out tomorrow and take a picture (if I remember  :loco:).

Ksor.

That particular posting was removed, from several forums.

The design was much too close to someone's patented design. And, they complained.......
