--- Quote from: raynerd on July 12, 2015, 03:55:53 PM ---Hi John, It is cz120 aka half hard brass or engravers brass. Try and use anything else and I have found it a waste of time and effort...good luck. --- End quote --- As Chris says CZ120 is the recommended material. The more commonly available CZ108 is too soft and a) won't machine cleanly and b) the teeth will likely bend. I used http://www.engravamet.co.uk for my CZ120. Cheers Phil |

Thanks again for all the responses. I will try to source the cz120 locally and if I can't will have to order it. I'll make this a small project on the forum with some photos - might scare a few of you who are more adept than I but I do feel that with my equipment and skill (pretty rudimentary I must admit) I can produce a suitable gear. Fortunately the gear is a decent size so I won't need an electron microscope to work on it. John. |
