| 429 forum posts 268 photos | I've made a few dead centres for my watchmakers lathe but I can't seem to find any information on the right temperature/colour for tempering. Can anybody help? Steve |

 2376 forum posts 800 photos | For a carbon (silver) steel Tubal Cain recommends 200C, which is pale yellow - the first hint of colour when tempering. HTH, Rod |
