re: Wood working question- Update: Finished pics on page 3

How long are those beams? Moving the beams over any stationary saw would be difficult if very long. It seems finishing these tiles would take some effort also being as saw kerf and white oak make for big time work. A few very nice spiral head planers may help with finishing(end grain doesn't plane well) you may need them finished with a sanding machine to ensure uniform thickness. All in all very much effort and special equipment add up to real dollars. To answer the question a bandsaw would be best choice. Wood loss on each cut would be minimal and with a bandsaw and a blade of at least 1 inch width you get it done. Expect dull blades quickly.
