This tutorial demonstrates how to construct a precision DIY circle cutter and burn bar for your oxy acetylene torch to achieve cleaner, more accurate cuts. Follow along as the instructor sources scrap parts from around the shop, builds a burn bar for straight cuts and bevels, and constructs a circle cutting tool with detailed breakdowns of each component. Learn the proper TIG welding machine settings, how to build the slide bar, attach the stand-off center punch, construct the 90° wheel hub, and create a torch slide for straight lines. The 14-minute video from Weld.com includes time-coded sections covering the entire build process from sourcing materials to showcasing the finished tools that will help improve your torch-cutting accuracy.
