Hi guys. I am old person but not very old. I have a qustion that is very important for me to be answered. How can you cut simple geometrical shapes from a irregular solid using simple methods only? By simple geometrical shapes I mean cuboid, cylinder, pyramid and sphere. stuff like that. You are not allowed to use any modern technology like lathe or anyting made using modern technology. I wonder this because at some time in history somebody must have done this somehow. I mean they did not find a lathe machine while walking in the forest right? For example I tried to cut a 25 cm long cylinder with diameter 3 cm out of irregularly shaped wax(it was big wax) and believe me whatever I did I could not make a perfect cylinder with these dimensions. I know it is impossible to make perfect cylinder but at least something close to it, for example with 1% dimensional error. modern machines do it as low as 0.0001% error. so I am not asking much. what i did was about 10-20% error. using hand cutting and eyes as a feedback you can only do that much. imagine yourself in ancient time with no moder technology around and try to figure out how to do this. you can only use atuff available at that time like stones, fibers, cloth... and shape a wax (or other easily cuttable solid like wood, butter, wetted soil) as a close to perfect cuboid, cylinder and sphere. its like sculpting, but a simple geometrical shapes rather somebodys face. this was long but only way to explain you what i want, and i will be very very happy if you find something. please reply if you do.
