When making paper logs for fuel from newspapers, don't bother purchasing a commercial machine. In my experience they don't work very well. (I gave mine away!) All I do now, is:
Tear and soak the newspaper in the usual way. Squeeze it into a largish ball.
Wrap it in an old tea towel or half a discarded teeshirt. Twist the end of the towel until it is the shape of a Christmas pudding.
Leave the end tightly twisted and place it on a paving slab. Place another heavy paving slab on the top and leave for about an hour (longer is better).
Unwrap it and leave the log to dry.
(Of course, you can make multiples in one go and are only limited by the number of tea towels and heavy weights you possess.
May be a good idea but since I have never made these "logs" I have no idea what the "usual way" means (put in a pan and soak with water?)
Also, I have no idea what the shape of a "Christmas pudding" looks like. I would like to try this but will have to dig further for instructions. Thanks for the idea.
