Youtube video of the Hoe Cylinder Press at Black Creek Pioneer Village.
This Youtube video is about 10 or 12 years old. It doesn't really show anything about how the press works. However, Black Creek has left it on their website.
The dvd “Of Man & Machine” is more recent, and does a much better job in 15 minutes on the history, restoration and operation of the press. The "footage" of the press mechanisms is wonderfully clear. The creators also included a booklet that clarifies some of the technical stuff.
This dvd is available to order from Jim Hunter at Black Creek Pioneer Village. His email is firstname.lastname@example.org, and his Black Creek phone number is 416-736-1733 (ask for Jim Hunter). The videos are available for $15 CDN, which includes postage within Canada ($15 USD includes postage to the US).
