Message: <blockquote data-quote="trains" data-source="post: 7643441" data-attributes="member: 130941">here is a chain, full chisel stihl .404 that was sharpened previously with a grinder.I re did the chain with the basic stihl guide and 5.5mm file, then did the rakers with the progressive raker guide.Note how the basic file guide holds the file to the tooth and how its a different shape from the grinder, this sets the top plate angle etc.it needed at least 4 passes to get the file to shape the tooth correctly, and yes the file also rode on the bit in the gullet, so I removed the gullet first with the file free hand, checked the rakers with the progressive raker guide, and took a tiny bit off them so the guide would sit correctly positioned on the top of the tooth and raker,  and then did the rest of the tooth.[ATTACH=full]953231[/ATTACH]see the gullet where the excess material has been left from the bench grinder process.[ATTACH=full]953232[/ATTACH]then I free handed with the file out of the guide to tidy up the gullet, and put the file with the file guide to the cutter.[ATTACH=full]953233[/ATTACH][ATTACH=full]953234[/ATTACH]you can see that there is still an area in the middle of the tooth, from the top plate to the gullet that still has the grinding wheel profile in it, but as I continue to sharpen the chain, that will go away.hope that helps.</blockquote>
