Hey all, we just had a great experience building and using a broadfork for the first time. We broke up new ground on our homestead in northern BC, Canada. If you're interested in the process or the results check out the video:
I get raw stock suitable for this project , every time I tear down a chimney and fireplace. It's available for free in Victoria.
There's a much more suitable recycled material available for making tines. Planer blades can only be sharpend so many times before they reach a point where they don't fit the machine . It's different for each type . Some of the big commercial units used here on the west coast, have a blade large enough to build a froe. Smaller models are perfect for making a broad fork. They are made of really tough metal that is pre-drilled. This would give the option of attaching them to a hardwood block with a handle similar to what you would have on a mattock. A workable broadfork for the millions of people who don't have metalworking tools or skills .
Glad you enjoyed the video. I sorted through the odds and ends at a small local metal shop and that's the best material I found. I also tend to err on the heavy side given the lack of "engineering" on my projects.
