Tom Edward Posted May 7, 2014 Report Share Posted May 7, 2014 Hello I recently purchased a set of watch makers engravers, has anyone here seen this type of graver set before? The graver blade that is curved and dropped also bends to the left, very unusual and really interesting, thank you for any replies. Link to comment Share on other sites More sharing options...
marcel beaudry Posted May 8, 2014 Report Share Posted May 8, 2014 Hello They are called EFB graver's. The one that is bent is for engraving inside rings. Marcel Beaudry Link to comment Share on other sites More sharing options...

Tom Edward Posted May 15, 2014 Author Report Share Posted May 15, 2014 Hello and thanks to both of you for the replies. Alain can you tell me more about those tools made from old taps and reamers, ? what kind of taps? the reamers I take it are jewelry reamers. I want to start using my et on bone and ivory but the sharpening process is still a challenge, what type of stone is best, not mediocre but best? thanks once again.

alain Posted May 18, 2014 Report Share Posted May 18, 2014 I have worked all my life as a maintenance engineer in a steel factory , where the made steel wires , all my taps and reamer came from the trash bin , most of the taps are long shank taps , 5 , 6 , 8 , 7 ,10 mm , as well as the reamers , adjusted by a electric grindstone , No jewelry reamers , too small and fragile , For sharpening, I use diamond plates sharpening , coarse , fine , extra fine , https://www.google.b...m=isch&imgdii=_ and a old carborundum stone , youtube vid's http://www.youtube.c...rpening+chisels razor-sharp edge, use a honing compound , power Honing system , http://www.toolpost....ng_systems.html or a other honing compound , https://www.google.b...iw=1483&bih=894 The ezra bowman gravers I found on german e-bay a decade ago , only the steel chisels ( 20 pieces) without holders , for 20$ , the curved chisel can be used ,when there is a bending , (pothole ) slope in the workpiece , Now on e-bay , ezra bowman gravers , http://www.ebay.com/...nc&LH_PrefLoc=2 Link to comment Share on other sites More sharing options...
