Thought i'd ask you knowledgable lot first.... Its probaly been mentioned before somewhere
Traditionally i've used a file and gauged the amount being removed by the cutter bar...not entirely accurate but it ultimately cuts the grass
Anyone any idea how the pro's do it and if it could be replicated easily at home. i own a Harrison L5 lather so could remove and spin the cylinder between centres. i thought of making a traversing angle grinder holder but need ideas/inspiration
Hi Stig, I own an L6 Harrison and I have trued and sharpened a couple of mower cylinders in the past by mounting them between centres and driven by a dog and faceplate setup,though a 4 jaw chuck would also provide a satisfactory mounting arrangement.
All I have ever used for this operation is a brazed carbide lathe tool and taken small cuts using the longitudinal power feed until the cylinder is cutting on all blades,then a final sharpen of the lathe tool to take the final cutting pass.
You need to spin the cylinder at fairly high rpm and feed at a slow rate to ensure the tool doesn't dig in.
If you go this route do some static checks on each blade with the cylinder mounted btwn centres to determine any abnormally high spots.....OZ.
