FILENAMES: rudderpost-1.jpg rudderpost-2.jpg DESCRIPTION: These are photos showing a tapered square being cut on the end of a rod. Posted by Tim Leech . Tim provided the following description: ================================================================= The two files here are in response to a thread on making square ends on chuck keys; they actually represent the forming of a tapered square on the end of a 63" long, 1.25" dia rudder post for a canal boat. The squaring was done simply by using a square on the machine table. The squareing is to receive the base of the tiller arm, known in the canal parlance as the 'Ram's Head' for rather obtuse historical reasons. Next stage was to drill & tap the squared end 1 inch Whit for a securing stud.
