Ive been a machinists for 30 plus years.. filing a square chain doesnt look to difficult.. I may be wrong.. my question.. im wanting to put the square chain on my dolmar 5105 I think its a 18 inch bar.. would there be any issues with doing this? also.. in general .. how much faster is a square chain compared to a normal chain? thanks!
It's not too bad but you're holding 3 angles at once and trying to stay in the corner of the cutter with the corner of the file. It will depend but I've seen up to a 30% increase in cutting speed with square from off the roll round chain.
