those pictures helped me see more of what I have been looking for. are you using ripping chain to cut those boards with? they look real smooth to me. are those wedges used to keep from marking the cant?
I have used ripping and chisel chain ,ripping or semi chisel will have a round outer corner so will not dig in as hard for marks ,but i get nice boards with chisel also ,you will have to sharpen at about 10 degrees instead of 25-30 like reg chain ,main thing is not to force the saw too much ,let it feed on its own with minimal pressure for a nice finish ,a few feet into a cut i will wedge the end of the log where i started so the upper board does not set on the bar and mark it up ,if doing a long pass like 12 feet i will wedge both sides about halfway down the log ,the wedges on the side do 2 things ,they support a wider area for clamping ,and stop the dog bolt from digging a hole into the cant ,a scrap chunk of wood will work also
On the norwood ,i just stand up and walk along that ladder holding handlebars with remote throttle ,i like that because it keeps the sound further away and the exhaust smell of the saw away from your face ,is very easy on the back also because you stand up without hunching over ,something to consider if doing several hours of milling at once
That little peavey is a back saver also for flipping the cants upright ,as are those small forks on a tractor or skid loader ,logs are heavier than they look ,if you look close under the dust can see the wood beams i mounted the mill and ladder to ,i can pick up the whole setup and move it with the skid loader this way and it stays square ,i had it mounted to my car trailer for a while ,that was a nice flat base also ,but i need the trailer eventually
the left hand chain is ripping ,the rh is 3/8 or .404 chisel at 10 degrees ,notice how much thinner the ripping chain is over reg .
