Sturmey Archer hub spacing
I have a 56 Sturmey Archer AW hub that I want to lace up to a 700c rim and install on a bike that has 120mm spacing. What are my options to make this hub fit the frame?
1) Cold set the frame to the SA spacing?
2) Add spacers to the SA hub?
Another question, when building the wheel (first time building btw), do I need to dish the wheel or just build it like a normal front wheel?
Once I find the right rim, I'll get to use my "new" Park truing stand

Most Sturmey-Archer hub installations are around 114 mm spacing.
The axles generally came in either short (5 3/4") or long (6 1/4") sizes. The longer size will generally work on a 120 mm frame, just add enough spacer washers to fill up the space.
Beyond 120, with typical 6 mm thick dropouts, it gets pretty dodgy.
If you don't already have them, you should pick up a pair of the HMW494 axle washers designed to fit the wider dropout slots.

I recommend spacing the hub to 120mm. That's better than bending the frame, because I just don't think you need to.
The rim should be centered between the locknuts. This may mean the wheel will be dished, but not nearly as much as a bike with many sprockets on the rear. Either use a dishing tool or flip the bike around in the truing stand several times to make sure.

+1 on the washers for achieve the 120 spacing. It worked perfect with my Raleigh Road frame.

I've swapped in the longer axle on all of my Sturmey Archer conversions for 120mm-spaced bikes. It also gives me a chance to overhaul the hub.

If'n you go the longer axle route, you also should get the proper indicator chain for it, so that you can adjust the shifting without guessing. SU-HSA126 at BikeToolsEtc. I think that they have the long axle too, at least they have something called "pre-NIG 6 1/4" axle", whatever pre-NIG means.
