BackyardBowyer on YouTube makes a variety of PVC bows with complete instructions and is very clear. The Mans Cave video has a lot of errors that make it more like a $30 bow because of all the mistakes and “guessing”.
I really like the “BackyardBowyer” (Note: Small typo on yours), he actually made a book as well. Which might come in handy in an off grid scenario. I like his videos very much.
I was going to tell everyone to look up Nick the backyard bowyer and here everyone beat me to it!
Have build 2 of these for a 1/10 price of my recurve and I would feel way more safe taking the string off this and using like a stick to fight with than a bamboo stick or training sword. Completely accurate, light weight and can easily be made after shtf.
