This dowelling jig came from an Emerald property which had been owned by the Alexander family since 1920 and was at the property when current owner (and donor), Karen Alexander, moved there in 1986. A dowelling jig is a purpose-made tool that takes the worry out of drilling the holes into which the dowels will be inserted in joinery.
