I want to thank you for all the replies. I have read them all. I did purchase a 6" battery-powered version from Amazon. What is more, I did appreciate all of the recommendations to get PPE and some of the stories about why they are important. Therefore, I got a proper chainsaw helmet and chainsaw gloves. So far, the little chainsaw seems to be working as well as we hoped. Safety can never be overstated when it comes to the potential of life-altering injuries.
Also, I will say the breadth of practical knowledge that the rocket community has is a true gift. There are some very smart and experienced folks in this community are more than happy to share their advice. Good on ya!
Thanks again.
