Abstract
Method for cutting heavy wall steel tubing. The tubing is notched and cut through along a vertical axis but the blade is narrower than the interior diameter so as to leave the side walls uncut. A side wall is preferably notched during the first cut. Thereafter, a second blade is driven horizontally through the side notch to complete the cut.
