I had some mud/dirt inside the axle nut...couldn't get the mud out from the outside...I had to take it off the axle and use a q-tip.

I just thought up something.... you use a very small straw that can go into the hollow axle, to bypass any dirt on the ends of the axle and axle nut. Straw would also allow very precise measure.

The grime is a good thing.

Sturmey Archer hubs were lubricated by an oil bath that is contained fairly well, but some of the oil leaks past the bearings. First of all, it's your automatic chain oiler. Second, the oil creeps out to the outer surface of the hub, where it attracts dust, and forms a thick black coating. I have wiped this coating off of 50 year old hubs, and uncovered bright shiny chrome with zero rust. I tend to open up old hubs out of habit, to inspect the innards. I once found a broken pawl spring, and another time, the oil cap was missing and the hub had run dry, but the only apparent effect was that the metal parts were covered by an extremely fine layer of reddish brown rust. After lubrication and re-inspection a year later, that hub is in perfect operating condition.

I use regular washers. The problem is that the hub flanges are narrower than flanges on typical modern aluminum hubs, so the garden variety spokes have too long of a bend. I'm sure if you're in the industry, you can order the right spokes, but for the rest of us, a plain 2 mm washer under the spoke head does the trick.

I've seen eBay prices all over the place for old SA hubs, so it might take some time to find one. Prices seem to depend partially on the number of spoke holes. There are a lot of 40-spoke hubs from English bikes. The 36-spoke hubs are likely to come from old Schwinns. In fact I bought a dilapidated old Schwinn for 20 bucks, and harvested its hub. Another issue is axle length. There were two lengths of axle, and the shorter one will require more effort to fit a modern frame.

In the final analysis there may be a variety of reasons to just buy a new hub, namely, it will have a more modern axle length, and will come with all of the goodies that you need to use it on a bike.

Nope, aluminum can be just as bright and shiny if polished.

And, The CR18 rims in the 590 mm size are delivered polished. They are pretty shiny -- you can tell by loking that they are aluminum instead of chromed steel, but they are sufficiently shiny and won't rust. Treefort has them in 36h for about $30. Amazon has third party sellers with both 36h and 40h for $32 or so with free shipping, I think.

Spokes, as always, are a problem. Treefort has Wheelsmith for $24 for 50 2.0 straight spokes. Can find spokes for a little less, I suppose, but unless you order form Europe, they won't be much cheaper, in my experience.

I don't know if the mtb_addict has identified the bike he wants to fix, but a complete donor bike, either an old 3-speed Schwinn or Raleigh, might be a consideration. Could harvest the hub and maybe other useful things and if patient, these old bikes can be found pretty cheap when the paint is no longer good and rust has retaken the chrome/steel.

Yeah I'm diligently searchin Craiglist and FB everyday for old vintage 3-spd donors.

But I haven't found anything cheap. My guess is there're alot of hoarders out there. In this day and age, almost everybody knows it when they got valuable stuff.

And I live in suburb, far from the city, so I can't always jump to it fast enough. And I absolutely hate driving into the city's traffic.
