I kind of hate to admit it, but I'm actually running EIGHT
7 speed cogs on an 8/9 FH.
I sanded the spacers down.
The lock ring is about 1 thread short of "properly" seating, but I don't see any problems with that.
I do have friction shifters though, so I didn't have to get the spacers perfect. Yhey are probably within .002" of each other though.
Originally, I wanted to make a "custom" 7 speed.
I had a-

I then pick up a pair of wheels for $5 at a garage sale. The rear was trashed, but had an 8/9 FH on it, and the mind started turning.
I picked up a 2nd position 13T from LooseScrews.com and went to work!
(it turns out I can use the original 13T top cog as a 2nd position cog anyway)
I can now make up combinations using 12 to 19 in 1T increments, + 21, 23, 24, 26 and/or 28.
My combination "this week" is-
12-13-14-15-16-17-19-23. It works great for my flat "city style" riding. I stay on the middle (38T) ring, since I can rarely go more than 6-8 blocks without a stop. If I need higher gears, I have 4 more nicely spaced gears on the big ring. Actually, one is almost the same as M-8, but by the time I do a double shift to B-5 with my friction shifters, it works out about right.
