Hey, Justin,

Nice video. That picture of you holding the board while cutting it with a knife around 0:25 was kind of scary! I hope you put the board down when you did the actual cutting.

Indeed. I had to sever the copper pad (on the bench). Here I am just cleaning out the slot of copper shavings.

Thanks for having a look,
