Whether you do it now or later .... When I'm ready to go down to final on the stock forward of mortices . The majority of the bulk is gone from the roughed in work now.....the finesse ... Where the flats are you gotta make them come to a point , as pictured . Break it up .... I like to do the ramrod channel with he barrel in for rigity . Put the barrel in and in the vice file the length of the channel , taking the edge to a nice even height the full length .... Look down it lots ....when done flip it over and do same on other side ..... THEN .....barrel edges .... Gotta take the barrel out . Nice you've done the edges on the ramrod sides you have good practice under your belt , just work in shorter lengths because the stock is gonna flex a bit ... Just keep working it , looking at edge and looking down the length , both ends . Do one side to finish , then the other .
