Sorry I forgot to mention in my first post I also have a collection of mowers mainly Victa, a Pope, a number (6 I think) Atcos, a Ransomes Sims and Jeffries ( have been told 20's but will post photo for help) Suffolk Colt, and a number of hand mowers.
My Grandfather had an after work business sharpening reel mowers, when I was old enough I would help him, he had a stroke so I was given his machine (this is approx 1973) which I operated for a number of years but then stopped as my career took a different path and did not have time.
I still have the machine so intend to resurrect it and hopefully once I have a few engines mowers etc to display will take it along to rallies etc to show it operating, I will have to modify it slightly as when it was operating it was powered by one motor driving an overhead shaft that had two wooden flat pulleys driving down to the machine as there are two speeds required to operate the machine.
I think what I will do is run an old 240volt generator/alternator that I have with a Ronaldson or some such driving it and fit two electric motors to the sharpening machine, see how I go.
Will keep you posted once I start.
Regards Beech
