My bucksaw featured in a previous picture and is quite simple to make. There a many different designs of bucksaw and this is mine.
I prefer to use an Ash sapling, but Hazel, Wych Elm and many other woods will work just as well.If selected carefully, all the parts for this saw can be cut from one sampling. The two vertical piece have a groove cut in at the bottom using either a knife saw or piece of flint. This is where the saw blade will sit. About 25mm down from the top of the two vertical pieces I cut a small groove around into which the tensioning cord will sit. To secure the horizontal piece in place, I make a mortise and tenon joint.
Finally I make two wooden dowels which fit through the holes at each end of the blade to help hold it in place, put loop of cord around the top and using another piece of wood, twist the cord to tension the saw frame. Now it is ready for use.
