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)
Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to this rule.)
