Glad it arrived safely sir, and even better that it's working out well for you!
I'm glad that it works okay on your Surge. Due to slightly different design & construction, on my Surge the saws don't work so well. No such problem with Charges and Waves.
I had not tried mine on copper tubing yet. Good to know that it presents no problem. I look forward to hearing about other places it works (or doesn't work) for you.
