If you understand the principle of how a torque wrench works,pound/feet etc,you can easily make a torque wrench using something like a fishermans spring scale (small and light) and a tommy-bar (you will probably be carrying this anyway) marked to one foot.
Simply hook the sping scale around the tommy-bar at the one foot mark and pull the other end of the scale until it reaches the desired weight,say 20lb,to give a torque of 20ft/lb.
If you applied the same 20lb to a two foot tommy-bar,you get a torque setting of 40ft/lb while 20lb applied at 6 inches (half a foot) would give a figure of 10ft/lb..
All you have to remember is torque is the product of a mass at a distance.
