On this page will be pictures of sculptures I made in Fall 2013. The first one completed was a (3,5) torus knot carved from Jobillo wood, shown in the next two pictures.
The next eight pictures show the two sides of a bronze torus knot cast on November 22, 2013. Removal of the core was done using a high pressure water hose through two windows left open in the casting. But there were many imperfections in the casting process which created holes and two large gaps, all of which have been filled in by welding. In the first two pictures, the evidence of the gating has already been ground away, and the core pins have been removed, leaving six additional small holes, as well as the windows. The second two pictures show the piece after the windows have been welded back in, and some other welding repairs and polishing have been done. The next two pictures show the piece after most welding repairs have been completed and polishing has been done up to 120 grit, but the mounting rod has not been installed yet. The last two pictures show the piece after the mounting rod has been welded in place, some repolishing has been done, and the sculpture mounted on the 12"x12" bluestone base over a curved mirror. This (3,5) torus knot is 11" in diameter, 4" deep, and weighs approximately 22 pounds.
Below are three pictures of the iron torus knot that was cast in Spring 2013, but which had very serious defects from its casting process because the core shifted. After a lot of welding repairs and polishing, the surface of the piece has been made reasonably smooth, but still contains small imperfections which seem beyond my ability to remove completely. Some additional polishing on the inside of the curves remains to be done.
Here are pictures of the two sides of another (3,5) torus knot I completed on Nov. 29, 2013, this one carved from Tineo wood. The diameter is approximately 5.5".
Next are pictures of twists I carved from the centers drilled out from the wooden blocks I used to make torus knots. The three kinds of wood these came from are cherry, tineo and cocobolo, with heights approximately 3", 2" and 1.75", respectively. They were completed on Dec. 8, 2013.
Here are three views of a (4,5) torus knot carved from cocobolo wood. The original block of wood was 4"x4"x2", but after carving the piece is 3.5" in diameter and 1.75" deep. The wood that was in the center hole of this piece became the small twist shown above.
Here are pictures of the two sides of two wooden torus knots I am currently carving. These show the pieces at the stage where the rough shape has been carved following guide lines drawn on the surface, but no finer polishing has yet been done. The larger piece is 8" in diameter, cherry wood, and has two disjoint (2,3) knots linked on the surface, so I have decided to distinguish the two valleys by having one concave and the other convex. The smaller piece is 5.5" in diameter, tineo wood, and has a (4,5) torus knot carved on its surface, as I have done with several other kinds of wood.
Here are pictures of the two carvings above after completion. I am sure the larger one is cherry, but I am not so sure the smaller one is tineo. I am starting to lose track of which kind of wood I have carved! I still have one more 8" diameter piece of Timborana wood waiting to be carved, but I have not decided what pattern to make it.
Here are pictures of the two sides of a (4,5) torus knot I carved from a 3"x8"x8" block of Timborana wood. The first two show the stage of the process after I have finished the rough carving to get the shape and also finished the first stage of polishing with an 80 grit flapwheel. The second two show the finished piece after I have polished it further with flapwheels of grits 120, 180, 240 and 320, and waxed it to seal the wood.
