Each of these power hammer designs are made by me (Roy Adams) here at Christ Centered Ironworks. Each of these videos has downloadable blacksmith power hammer plans at my website www.blacksmithpdfs.com . These homemade power hammers have professionally drawn up PDF files which cover the parts and measurements in depth. These hammers were constructed using basic fabrication methods such as cutting, drilling, welding, etc. Check back here often for more great power hammers, as I build and release them several times a year!
