Bottom bracket noise.

[ian]

I replaced the BB bearings with new #66's.
Fresh grease, cleaned the cups. It makes almost constant noise pedaling uphill under load. Anybody have any tips?

sounds like chain & cog relationship troubles

Maybe BB assembly is loose. Check crankarms for lateral play, tighten adjusting cone as needed, not overtight.

I was wondering about that. 96 year old chain could be a little tired.

I cleaned and greased and replaced the BB bearings, but I should take a closer look at the cups.

I'm with Scott--check chain. With a BB problem you usually 'feel' it more than a chain unless you have stiff links. V/r Shawn

I also had that issue with a Morrow hub that had too much play in it. After adjusting, the cog lined up with the sprocket better and the noise disappeared.

The chain seems pretty limber and smooth. Maybe it's stretched and too far gone. It seems like I can feel some friction or drag, and it's definitely noticeable and loud.

There is a bit of side to side play, maybe less than an eighth or so. I'll investigate more. Thanks Jay.

can you post a side-shot pic the cog?
has the chain or rear wheel/cog been changed?
