Vacuum fabrication of composite sleeves/tubes

Hi guys, I’m working on a project right now which involves fabricating composite tubes. I wanted to ask you folks if you’ve ever fabricated a tubular structure using Vacuum bagging or VARTM, and if you did, how did you go about it? If you haven’t do you have any ideas or suggestions?
Here’s a video where they show(besides boring me to death half the time) one way to do it: https://youtu.be/8iJH8P9KxAs
First time fabricator here, so please go easy on the jargon with me :slight_smile:
Cheers!
