Crann Posted July 8, 2017 Share Posted July 8, 2017 Hi, couple of Ammonites that have a thin layer still, lovely colours underneath that I would like to get down to, what's the best method you guys/gals think to get the best finish ? Thanks. Link to comment Share on other sites More sharing options...

JohnBrewer Posted July 8, 2017 Share Posted July 8, 2017 I guess air abrasion. I've got an AEC Air Eraser , and I know a few other members use similar. @Malcolmt came up with a fantastic method of using a hypodermic needle to give a really fine jet but I can't find the thread. 1 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Ludwigia Posted July 8, 2017 Share Posted July 8, 2017 I agree. Find someone who has an air abrader or better yet, get one yourself. Of course you'll need a compressor to run it. Sanding and polishing is not good in my opinion, since you'll lose the lovely sculpture in the process. Greetings from the Lake of Constance.

Hi, I have a compressor as I'm currently prepping, will look into an air abrader I think, cheers. Link to comment Share on other sites More sharing options...

RB Can you tell me what I would need to start this ? Seen some abraders on eBay, how do they work ? Thanks Link to comment Share on other sites More sharing options...
RJB Posted July 15, 2017 Share Posted July 15, 2017 Not sure you want to clean that up with an air abrader? Maybe very carefully with an airscribe. RB Link to comment Share on other sites More sharing options...
