Round tube is used in motorsports fabrication for its strength to weight benefits when it comes to roll cages, motorcycle frames, support structures and much more, however, it can be difficult to join when compared to other square tube options.

In this lesson, which is just one taken from a full Motorsport Fabrication Fundamentals course, we're going to cover the 2 main methods you can use to notch, the pros and cons of both, what tools you'll need and from there it's only a matter of practice to refine your notching skillset.

For this example, we're creating a 45-degree notch using 1.5" / 38.1mm tube

YOU NEED TO KNOW:
- Notch Angle
- Diameter of both tubes
- Orientation

GREAT TOOLS:
- Notching Calculator: https://hpcdmy.co/ncy
- Angle Gauge
- FINE Tooth Hole Saw (if not using a grinder)
