I found a good video for friction welding. Anyone have any others?

I saw a few other videos on the topic, but this seems to be the best oit of what I found. There is always the idea of using ABS slurry to glue parts together too.
ABS worked for me, but PETG did not. I was not holding the rotary tool at the same angle as what is shown in this video for either one. I did not get to try PLA.
My guess he’s held the pieces down with tape and is probably using 3mm filament.
Just do it its easy. Amazingly solid btw
