I have a pile of timber in the form of old joists and rafters etc. Would it be a good idea to cut these up and use them for firewood.
Do they burn well ? I could keep the timber for a planned solid fuel stove perhaps. What is the best device to cut these up ?
Use a hand-saw for a bit of healthy out-door exercise.
There are very handy little electric chain-saws available that will make short work of them, but wear the requisite protective gear, including a mask. Or hire a saw and gear at a hire place.
If you intend installing a solid-fuel stove, the saw will be useful in the future.
If they are joists and rafters and you plan to break them by jumping on them you'd better be the same size as an elephant to make any impression on them.
