Yeah I make the paper logs with the contraption too.
for best results get a local business to suply you with their shreded office paper.
Soak it in a large tub overnight or two nights, I use a household dustbin, then take handfulls out squeazing lots of water out before putting into the contraption, this makes um more thicker and slightly less harder to dry.
Best to make um in the summer to stock up for winter, you can then dry them in your garden out in the sun and leave um in a shed overnight to fend from any summer rain.
For ultra best result, mix slack with the shreaded paper and water -slack being coal dust, most coal merchants used to give it away for free but I got mine from a friend that I bought some coal from as they had converted their coal fire to as gas fire, in their coal house was plenty of slack.
These lasted much longer than the paper log on its own, twice if not 3 times longer lasting.
You need old clothes on and rubber gloves for this one though, but I found it fun making and drying them and burning them knowing how much cash I was saving.
