I tipped the blade about 5 cranks from center so it was undercut slightly and that gives me a tighter fit at the surface.
The I routed a groove in the cut edge Because of the pattern on this floor I had to do that a lot. Bamboo smells a little bit like Pot when cut... Just FYI
I found a tip that you can take paint sticks for 5 gal paint cans and cut them into strips and use them for splines on your strip flooring. These fit into the slots cut by the .25 grooving bit making a instant tongue in the board.
