Tubing Expander
« on: August 09, 2020, 09:03:55 PM »
Someone posted about a new tool used to expand copper tubing.I was quite taken with this tool and how it worked, so of course I had to make one and try it. There is a description of the tool in the write-up which accompanies the video. Very neat trick!!

That is quite interesting. I read the description on the youtube post, but am a little confused about the geometry of it. Could you show some closeup shots at other angles, or a diagram?
