I am happily working on a Baby Ben clock from 1920. It's all going great, but I am missing all of the case screws except for one. It's a size 1 on the screw plate I have. I would really like to make the other screws, but am having trouble finding information on the actual sizes of the screws and the size stock I would need.

I've found this link that might be all I need, but I could use a little advice.

I don't know why, but I've become quite fascinated with the idea of making beautiful little screws!

You are not alone, it is interesting.

Baby Ben Clocks were made in the US. The screws used were most likely either UNC or UNF. (1-64 or 1-72) Machinery's Handbook is available in pdf downloadable free online. If you haven't a hard (paper) copy, you should download it. In there, you will find screw thread data for UNC, UNF, British Standard, Whitworth, Waltham, Elgin, and Swiss, among others.

Here is a link to a handy UNC/UNF thread data sheet.
