I made a video about something I made recently, it's a nice example of what I call overengineering. And I included a bit with a nice tiny improvement for my set of number punches.

I think there are at least two types of overengineering in the workshop, specs and features. I think I went a bit overboard on the features of this guiding block. And I am afraid I have to admit, not having punched long numbers into stuff before, I didn't even realise the option of using a scrap piece of metal as guide until I was nearly finished with this tool project.

(No workpieces were case hardened or surface ground during the creation of this project)
