How to notch tubing

To notch tubing you will need a tape measure, a welder, a drill with most likely a 1/2" drive, a tube notching tool, a hole saw that is the size of the tube you are notching for, a grinder or any other tool that will cut tubing, and however many feet of tubing that you need for your project. 

I am doing cage modifications for shock mounts. I first measure the length I need, give yourself about 3-4 inches extra so you can notch your tube. I am using 1 1/2" tubing so my hole saw is 1 1/2" as well. I change the angle of the tube for the notch needed by simply loosening the set screw on the tube clamp angle set, and tighten it at the desired angle. I like to clamp my jd tool in a vise and run the hole saw through the end of the tube. I then measure from my cut to the other side of the tube and mark it at the exact length I need. I run the edge of the hole saw down this mark and you now have your notched tube. Try to place it where you want it and see if there are any small changes you need to make. If it fits nicely., clamp it in place and weld it so it doesn't ever move.

Hope this is helpful. Any questions just let me know
