You could try ringing around the local bowling or golf clubs.there was a chap at Barwon Heads golf course who was a guru on roller mowers.I'm surprised that Fyans street could do it or put you onto someone. Mowers galore in Grove Dale had a chap doing it, so you could give them a try.Tony in Moolap, moolap chainsaw and mower repairs, can back lap the blades, and he has a sharpening machine, so give him a try. He doesn't do a lot of them, but at least he has a reel sharpening machine.
