Looking for (idler?) gear wheel of HP-46 printer unit
Hello all,
some time ago I was lucky to get a HP-46 desktop calculator. It is in good shape, but when turning it on there was a grinding noise from printer unit and when going through test procedure printer sometimes gave out perfect lines and sometimes total rubbish and in rare cases nothing at all. After I excluded any electrical reason I dared to disassemble printer unit. Reasonable cause for described behavior was (unfortunately) found easily: a deterioated (idler) gear wheel as shown in picture below. Now my question: Is there any hope to get a modern replacement for that wheel? As layman in that subjects it looks pretty special to me. Any known sources? Has anyone a forgotten printer unit of HP-46/HP-81 in a desktop drawer. Does it make sense to rebuild it with a 3D printer? Has anyone already created a model or would be willed to do it? Any idea or hint is highly appreciated. Thanks in advance! Werner |
