Have been asked for advice on making a folding wooden walking stick for a large heavy man. So its got to be something a bit stronger than usual. Was thinking of something like using 2 inches (5cm) by 3/4 inche (2cm) in cross section size.
I searched and read the preferred wood for making aircraft is Douglas Fir, so i thought that would be good for this stick. (good strength to weight ratio) but I guess that is difficult to buy already cut to size here in London. U.K.? Would some kind of building grade plywood be stronger, I wonder?
The tricky part would be some *self-locking* hinge. Does such a hinge now exist? I remember very many years ago seeing such a thing (I think on something agricultural). Would be grateful if anyone had advice on this. Thanks.
