Steuart Goodwin asked for a set of toe cones to form toes on pipe feet.
A brass rod was purchased from the local scrap dealer, and then cut into blanks of proper lengths. The ends were faced, then center drilled. A boring bar was used to hog out the insides, then a reamer of proper angle used to finish out the inside cone.
The cone was then chucked up and a shank turned on the other end of 1/2" diameter. This allows the cone to be chucked up and motorized for easier deformation.
The three cones have internal angles of 40, 60, and 90 degrees, and are 2.5" in diameter.
