Using an oxygen acetylene torch, with a prime setting of 5,000+ degree flame, you cut an end section of a steel beam, hot sparks shooting several feet across the shop. The end section drops to the floor. An electric grinder with a 7” abrasive disc is used to grind the end of the beam, a high-pitched whine and a shower of sparks requiring personal protective equipment. A heavy steel plate is cut to length, a sizable hole is drilled to accommodate a large section of round stock, and the whole assembly is welded with a shielded metal arc welding process. This is my visualization of my knee operation as the orthopedic surgeon described his operation procedure at my pre-op appointment. With some apprehension I will check in Monday for knee fabrication.
