According to John Hurley's book on shillelagh making, the stick was rubbed with butter or lard and put into a chimney to dry. The manure pile was soft moist heat used in the straightening process, like a steam box, This was a finishing step.
Its not a great book for makers, IMO. Hurley does do history very well though.I have not read that book. Looked it up and orderd it. I looks like a good book to have. I want to do more natural sticks and cane. Thanks for sharing.
For traditional Irish shillelagh making this guy is probaly the best source of info.Its not a great book for makers, IMO. Hurley does do history very well though.
