After reading all the messages about infills, I decided to construct them myself. As an mechanical engineer, my approch is different to the traditional way of peeing metall plates.
Another focus ot my construktions were the ergonimical handling, so I tried to make the handles as comforting als possible.

Here is the history of my first three planes ( which I have already posted on woodcentral)

The original pages are in German and automatically translated by Google, so they may sound sometimes a little funny.
