The rods...

[Shmackey]

Guess it pays to stay away from BF for a while. I come back and POOF! the diamond rods are a reality. No more sandpaper and binder clips for me (but hey, that really did work).

One question: can you use the corners or do you have to use the flats?

Corners and flats both work.
Great to see you back, buddy!
