Here’s two relatively little-known Scout pioneering methods that are well worth investigating.
This new (to me at least!) Scout pioneering technique originated with the Italian Scout Group Trento1. CatDrill combines classic pioneering and froissartage (see below). This technique uses smaller diameter wooden poles or branches and lighter cordage to make sturdy joints that can be used to build a number of different projects.
The basic technique involves shaping a “diamond head” and corresponding “partridge eyes” (drilled holes) that are joined with light cordage (like paracord).
These PDF directions are in English and should help you learn the various techniques involved in CatDrill.
Froissartage (pronounced froy-sar-tage) is a Scout pioneering technique named for its creator Michel Froissart, District Commissioner of Scouts France at Fontainebleau in the 1930s. Frioissart adapted a number of traditional colloquial woodworking techniques to build semi-permanent camping furniture and structures.
