I was about to post another submission[1] regarding DIY farm tools that someone had commented on saying they thought it was another case of it being crap, but were pleasantly surprised that it had some good ideas, and in making sure it wasn't already mentioned came upon your comment. Turns out, you're the comment in the other submission saying it was actually not bad, so I suspect you'll appreciate this link. :)
