TStodard Posted June 26, 2015 Share Posted June 26, 2015 What tool/tip is he using in that video? Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 26, 2015 Share Posted June 26, 2015 (edited) What tool/tip is he using in that video? That is an air scribe ( or air engraver,... air pen, ... air hammer,... all the same). It is a pneumatic tool, attaches to a compressor, and works like a mini jack hammer. Some people use cheap chinese models, some use a Chicago Pneumatics 9361, some use any of the Paleotools Microjacks, or other models. Some have success with the All Air Products model, which goes for about 100.00 bucks. There are many threads here on the Forum which deal with these questions.

TStodard Posted June 26, 2015 Share Posted June 26, 2015 Thanks for the info. I saw that video a few weeks ago, but did not know the name of the tool he was using. Link to comment Share on other sites More sharing options...
Mike Pocock Posted August 15, 2015 Share Posted August 15, 2015 You can get good results using an electric engraver this is a lot less expensive than the air scribe Regards Mike Link to comment Share on other sites More sharing options...
jpc Posted August 15, 2015 Share Posted August 15, 2015 You can get good results using an electric engraver this is a lot less expensive than the air scribe Regards Mike The results may be good, but they better with an air tool. My first air scribe was electric and it lasted but a matter of weeks. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted August 19, 2015 Share Posted August 19, 2015 There's a philosophical distinction that needs to be made when attempting any preparation job. You don't want to remove the fossil from the matrix. You want to remove the matrix from the fossil. If you look at a prep job from this angle, one is much less likely to damage the specimen.
