Tube Vise Build - Fireball Tool Style - Part 1

This is Part 1 of the Fireball Tool style tube vise build. I was inspired by Jason from Fireball Tool who made a video of building his steel tube vise. This type of vise is very strong as you can see in another video where Jason tests a bunch of vises including the vise he built. Many thanks to the following Youtubers for taking the time to record and share their vise builds. These videos have helped me in my build.
