Face Turning Octahedron

I didn't get enough sleep last night. I have been trying to remember, or figure out, the FTO today, but so far it has been 2 steps forward, 1 step back. Or sometimes 1 step forward, 2 steps back.
Should I set it aside and come back later? Or look it up? I looked it up. In the Solution Guides Pre Fall 2013 it has an FTO Family page. Family??? Evidently I considered the Rex Cube and the Master Skewb part of the FTO Family. And maybe they should be. I think both of those puzzles were in the nice metal case that got stolen. :(

So here is what the Solution Guide says to do with the FTO:
Corners
Get 3 of one color. The other 3 are either solved or need an EPS to solve them.

Centers
  1. Get the White Centers
  2. Solve the gray, blue, and red centers using go get it bring it home. Slice Face Slice' Face'
  3. 3-cycle the green, orange, purple, and yellow centers home.
Edges
3-cycle all the edges.

How it worked out for me.
Corners. Got 3. 2 of the other 3 needed to flip! I messed around with The Move (EPS) until it worked. Let's see. With a face toward you and a vertex at the bottom, and with the 2 that need to flip on the right do R'LRL' F' to flip them.

Centers. White was real easy. Gray, Blue and Red—The Move. Centers step 3 is sort of vague. It tells what to do but not how to do it. It came back to me. With a face in front with the vertex up you have a right face and a left face showing. You have a horizontal slice. To go from right or left to the other to whereever... yeah. It worked great!

Edges.

Phew! That was rough. Here's the deal. I have to really focus on what I'm doing. It is so easy to mess up and lose progress and have to start over. Maybe I'll try it again in another 7 or 8 years. :) Seriously though, I would sort of like to solve puzzles more often to keep sharp. Think it'll happen? Who knows?
