Sooner or later, if you are a do-it-at-home, hands-on kind of fabricator you will be faced with fitting tubing together to form a clean joint. By clean we mean the gap between the tubes intended to be joined is uniform from start to finish. The reason uniformity is essential is because uneven gaps weaken the joint and greatly increase the odds of burning through while welding. The expression for what needs to take place in order to join tubes together whether they are square or round stock is called a notch. There are more than a few ways to notch tubing, ranging from the high-dollar approach with a Bridgeport type mill to primitive handheld grinding, or hole-saw methods that can prove to be time consuming and ultimately inaccurate.
The quickest, easiest, and most accurate way to notch tubing while keeping costs to a minimum is to get your hands on an HTP Quick Notch or HTP Quick Notch Jr. from HTP America Inc. Both versions are made in the USA and are designed to provide years of service. We chose the HTP Quick Notch Jr., part number 90251.
