Picked up one of these today as a bit of an impulse buy. Does anyone know much about them or whether or not they are any good? It seems pretty solid but needs a clean... I’ve watched a few YouTube videos but can’t find any pilots running. I’m hoping to grind my own cylinder blades now along with the mowers I work on for others. If anyone knows about or has one of these I’d love to know if there is anything to keep an eye on etc. I’ve never used a cylinder grinder before and have just paid a local shop to do mine in the past.
