Had a bunch of 1/2" sheet laying around and tired of moving it again and again but too big to melt in my cast iron pot. Read lots of suggestions for cutting methods, axe, saws-all, chainsaw. Wanted it in 4" wide strips.
Thought of something I do not recall previously reading and it worked great. After cutting up wood pallets from my former place of work with a worm drive skill saw, cheap one from Harbor Frieght, gave that a try. Walked right through it, not much more difficult than cutting up the skids. Used the finer tooth carbide tipped blade that came with the saw (less after cutting a through a few nails in the pallets) and made a sheet metal hood to go over and in front of the saw to keep chips down and close. Most chips fell directly down, easy to clean up.
Thought I would share this.
