Flowforming - GIF

[hemmjo]

I had to do some experimenting after Jon posted those previous videos of the copper forming. This is just 3/4" copper tube down to about 1/2"



I just ground a piece of HS Steel cutting tool to a rounded profile. I was not able to polish the surface as much as necessary to get a really nice finish. You notice the surface is a bit rough, I feel like if I spent the time polishing the tool surface, the result would be much better.
