On the basis that the tools list topic seems to have been fruitful I'd like to start one where we can discuss useful things to make or upcycle that cost little or nothing. The emphasis is on things specifically for use in our woodlands - like tools or aids of some kind. I had my thinking cap on and came up with a few ideas.
To source materials and tools etc I have had some nice responses over the years from Freecycle. If you haven't heard of it, it's run by Yahoo (you need a Yahoo email address to join). Most towns/cities have their own local group. Basically people post adverts of stuff they don't want but don't like to throw away. They give it away for free. If you see something you just reply politely asking if you can have it then if it's still available, you arrange to collect. You can advertise for things you want too and you'll be surprised what people will give away. I was looking for old bicycle inner tubes to use as hinges for birdbox lids and a guy has offered my some motorbike ones. Cool or what? I got a small B&D bench grinder with new wheels a few months ago. Beware though, when you sign up you get all the ads as separate emails and if it's a big city there can be hundreds over a few days!
I saw these videos and thought how useful the "reaping hook" he makes would be for helping clear undergrowth. I guess you have a machete or bush hook in one hand whilst pulling and raking out brambles etc with the reaper. Gonna make me one when I get in there. Claypaws take note

I love OCPs barbecue fire made from a washing machine drum and the stake driver that Greyman made (photo in the toolist topic)
