Hey Deejay,
I really struggled to find someone that would sharpen it.
I'm probably being a little harsh on them, he just thought I had one of the hand push cylinder mowers, and their blades apparently touch to cut the grass. I explained to him that on our mowers the 2 blades go extremely close but don't touch.
It was just the guy at the front that I was talking with, sort of the receptionist. There was lots of other guys and machines out the back.
I'm pretty sure he said the cylinder was going onto a lathe type machine.
They came back to me as far as I could tell in the right condition, after a bit of playing around I was able to get pretty close to a consistent minute gap all the way across.
But other than to drive an hour and half to the only other place I found that could do it and pay 5 times the price I couldn't find another option.
