This method sure looks interesting. I'm going to need to make one new blade set this spring, and originally I though of using the "traditional" chainsaw method for those.. But this thing looks even easier I think.
For the side of the blade facing away from the wind, mayby it could be rough-cut with a chainsaw manually before starting with the planer, to reduce the amount that needs to be shaved off? I did that with my last blade set, keep the chain speed high and keep the cutting bar moving (sideways..) and I actually had quite a good control over it.
I think electric saw is better for this job, it does not have as much power as a gas powered one, but it's lighter and much nicer to use especially if working indoors. That's what I've used before for roughing up blades.
Has anyone experimented about how to best file the chain for this kind of job? I think I read from somewhere, that for cutting along the direction of the grain, it would be best to have a worn out chain (so the rake is quite close in height to the cutting teeth), and reduce the cutting teeth angle to 15degrees for best results..? I think I'd best try a few settings before actually cutting my precious blanks
