Probably not as refined as you are looking for but a friend of mine welded this quick and dirt branding iron out of some scraps and I turned a handle for it. I have to add the cross bar on the A using the edge of the iron but it works with less than a minute of heating with a propane torch. I have to be careful not to overheat it.
