There is a way to saw the entire log on a quarter sawn manner. You get a lot of waste. Saw mills are about yield and speed sawing. Quarter sawn sells well in white oak and some in red oak or sycamore. Most saw mills are not sawing for gun blanks. Those that are will do whatever the buyer wants but will charge more. Only fair. Out Of The Wood had a video about quarter sawing wood on YouTube if you want to take a look.
