1: chisel tip?
2: Cut a 1" length of 1" rod. Mark a vertical diameter on one end, and a horizontal diameter on the other. Grind off material such that the ground faces become half-ellipses, so that the curved "end" touches the tip of the horizontal diamter and the straight "end" is the vertical diameter.
(It might be easier and/or safer to do the grinding first, then the cutting. It is also possible to cut the diagonals rather than to grind them off.)
3: Extrude a 1" circle, a 1" square, and the 1"x1" triangle. Intersect them all at right angles (e.g. cylinder along the x axis, square prism along the y axis, and triangular prism along the z axis).
