I've decided to share a few videos I have made over the years. Hopefully they will give someone some ideas.
Here's are a couple of videos I did about a year ago. I used a two rail sweep to create a bowl.
It started as one video and was so long I decided to split it into two parts.
In the first part, I worked out my cross section.https://www.youtube.com/watch?v=bvNNvR07psA
In the second part, I did my two rail sweep. https://www.youtube.com/watch?v=cGq2CCO0oW0
