Firewood (chopped into short sections) (Peachcroft OX14)

Our wooden climbing frame was well used but reached the end of its life and couldn't be dismantled for re-assembly. Instead I've chopped the beams up into 'logs' ready to be burnt as firewood. There are circa 50 sections which are generally 7cm x 7cm (3" x 3") and 20-25cm (6"-8") long. It's pressure treated wood, some of which is a little rotten but generally solid - I've removed most of the nails/screws/fixings but some metalwork may remain.
