Well ChrisKY a lot will depend on the diameter size; and sawn lengths of logs you want to process.
More than just moving saw-head versus stationary with the log moving, is having to have a bed to dog down and turn the log to be sawn . . . Or Not.
The or-not is for circular single blade swing blade mills… The log section is either big and heavy then gravity held in place; or dogged down only once; then stationary.
The swing blade system does first the wide board cut as horizontal going one way forwards. Then on the reverse return, the blade is flipped 90 degrees and the one edge cut on the return movement. Once started then each forwards and back gives you an edged board or beam produced. You edge cut as you slab cut.
You work starting at 10 o’clock, or 2 o’clock on the log depending on how your flip system is set up.
Only five carbide brazed on inserts teeth to on-mill, sharpen on my N.Z. Peterson brand swing blade mill.
Look back and see how J.O. made up his D.I.Y. swing blade mill.
Watch Australian Lucas brand swing blade systems videos.
Canadian D & L brand swing blade videos also.
Ha! if you have chickens or goats the kerf-cuts strands and saw chips are not a waste. Dry, and then animals bedding.

Edit correct. My saw blades have eight teeth. Been years since I’ve looked. S.U.
