I plan to photograph and video the real one once I build it and post it on my site "which is not up yet".

Thank you for your question. That's exactly why I posted my design so that I could get questions and opinions before I started building my hammer. I am very new to blacksmithing and I have only used a treadle hammer once while taking a course and noticed an adjustment wheel but for whatever reason did not ask what it was for. If I understand your question correctly you want to be able to adjust/limit the height at which the head travels up? Currently I do not have an adjustment for that. I tried to keep the throat open. Where would you recommend placing an adjustment and how much would you like? Thanks again!

I am near the point of starting to build my treadle hammer and wanted to show my design and get some feedback. I have developed a linkage that allows the head to travel in a straight line without using any guide rails for the hammer. I admit that the mechanism is complex due to the amount of links required but that does not matter to me. Part of the reason is my affection for all things mechanical. The other is once I designed it I just have to build it. Over all specs are as follows. Height to "anvil" 38" with a "hammer" travel of about 16". The Base is a plate 22" X 28" and the overall height is about 87". The hammer weighs about 92 lbs. The relatively small footprint is a benefit of the linkage design. While researching straight line hammers I have only found styles that have a long pivoting bar at the top which takes up a lot of room. I have most of the steel which is 6" X 6" X .25" wall. The only items I will need to purchase is the material for the links and bolts. I don't have any specific questions other than I'd like to know how many people are interested in straight line linkage style hammers? I posted a video of the hammer in action here: YouTube - Treadle Hammer "Mack Hammer" Thanks for looking!
