In What is a Low-Carb Diet?, I outline three approaches to low-carb eating, only one of which focuses on ketosis as a goal throughout the diet. Diets such as the Atkins Diet start out as a very low-carb ketogenic diet, but as people add carbohydrate, many or most will be eating too much carbohydrate to be in ketosis.
At the core of any custom motorcycle project is the welding process used to join the tubing that makes up the bike's frame. This article will discuss how both MIG and TIG welding fit into this process and how even a novice welder can get started. (As seen in the Welding Journal, October 2005)
Steel for bike frames is primarily produced in two levels of quality. Lower-cost bikes are commonly made from 1020 carbon steel, since it's inexpensive to produce. It's not as strong as other types of steel, so the tubing in the frame needs to be thicker and much heavier.
