I've an open fire and in the past have bought kindling in bulk bags. However I've recently been offered a free supply of broken pallets so I'm thinking of using those instead, the only pain being breaking the buggers up! In the past I've used the chainsaw to just fly through them, which works wonders, but hit a nail and it's a chain resharpen or replacement which obviously isn't economical! Jigsaw is too slow, and doing by hand either with a wrecking bar or sledgehammer is just too slow as you still need to cut the pieces down to size. So I was thinking of getting a cheap circular saw, which I believe will be more resilient to nails (or am I mistaken there??) and will also be quick. But before I do, is there any other tool which is more suited to the job? Don't really want to be paying more than say £80 ideally because otherwise it just defeats the object of using free wood, may as well buy it if I need to spend hundreds on tools. Any advice/suggestions?
