There will be 4 Project Finals. Two of them will be stainless steel, on sheet-metal and one will be square and round tubing. There will be one chromoly project using round tubing and one Aluminum Project using Aluminum square tubing. Everything else will be practice for the types of joints that will be done in your projects. You will have 2.5 weeks(5 classes) to practice for each project and 1.5 weeks (3 classes) to complete them.
