I'm old enough:
This grinder was used (both in the field at times, and at the machine shed) for sharpening siclkle sections while on the bars. The sickle bar was pulled out of the guards, and worked on as a whole. The machine was clamped to a convienient surface, or angle iron and held steady. The sickle bar was clamped in to allow the sections (and the whole bar) to pivot allowing the sections to be ground from root to tip (the ocillation motion) Two surfaces were ground at a time, one on each of two different sections. That is a very close to correct stone, it may need a sleeve arbor to make it centered, but it is not wrong. The person grinding the sections could sharpen a bar on a 7 foot mower in about 25-35 minutes. (compared to replacing sections that took 2 hours. (and cost way more than my grandfather would consider rational) The sections were often not serrated as they are today, and if at all dull, were sure to plug the mower, or make stripes in the field (again the grand dad did not approve) They were a necessity. The steel in modern sections is so good, and the sections cheaper (it is considered) so it is not used except to show it off. I hope this is enough content, JimN
