David Cruickshank, over on his Orchid blog, has published a little how-to with pictures on how to make coiled tubing. While this has been discussed on Orchid before, I don’t think I’ve ever seen this published in a book or online. (if you know of a book, please post a comment, thanks.)
I learned how to do this when I was an apprentice, and I can attest that it works!
