Clam Plate with spring mod, M18 drill, 5ah batteries or bigger, and strikemaster Lite Flite. Cuts fast, very light and portable, easy to use. Win, win, win
I made a insulated box using a plastic ammo case. Used 1" foam ridged insulation. I toss in a couple hand warmers and the 3 batteries seem to stay warm. This year is the first time with it and our temps are outrageously above average so not a certain how it will perform at -20 or colder. I will be measuring some internal temps once our cold weather comes. Then I'll have a better idea if it's working.
