Wow, that's a lot of ideas/considerations to think about.
To input some more info as i did not at first see as important. I have
been using pallets and reclaimed timber for my business for 5 years and
of course use the scrap in the stove. But now the output is increasing
and always looking to earn a bit more i have a plan to remove unwanted
pallets, saw up on site or around the corner to save time and fuel,
then sell as fuel in bags. I use a 240 v jigsaw in the workshop
normally in the initial 'cutting up' of pallets for my furniture but
have no experience of 12v saws as in battery type but thought one could
wire one to the car battery, (i have a large one for the trailer winch
and a chunky cable to supply same). If anybody has done this and it
works i would find this favorite.
Thanks for all your input so far.
