Subject: Cog tooth spacing on old gears.
|
I'm looking at an old, single-cog US made hub. From tip to tip of the
teeth is measuring about 9/16", as closely as I can measure, anyway.
It's just a tad bit longer than the modern chain, such that it'll span
about three teeth, but no more.
So, what kind of chain and chain ring is it for which I'm searching?
If I knew what to call it, I'd be more likely to find it.

Thanks, but it was just a cranial flatulance on my part. I'm
considering grinding the cog to take the narrower chain. I always
ask: why do something the easy way (i.e., get a 3/16" chain) when,
with a little bit of effort, I can make it *much* more complicated and
difficult? It wouldn't be "The Cowboy Way"!!! (I'm from Texas.)
It's a damn good thing I don't make my living this way, huh, Andrew?

Try a motor-cycle chain, I think I read once that was the standard
track bikes used to be. 'Till this new fangled 1/8th trend came along
that is!

Let's see... that would be called the "pitch", I think. It's on an
old Bendix hub. It's definitely a longer pitch than 1/2". It'll take
a fairly wide chain, but the pitch is a greater issue.

9/16" is highly unlikely. More probably 1" x 3/16". Either
locate/finance/acquire a chain or count on changing the cog. A standard
1/2" x 1/8" track cog fits most. Which brand/model hub is it?

It's a Bendix red band hub from the '50s or so.
I have a piece of 1/2" X 3/16" drive chain and it's not meshing!

OK, I see the issue. My piece of chain is too narrow! It's 1/8" wide
and the hub predates 1/8" chains!!!
I did the math and it's almost exactly a fifty cent pitch.
As Gilda Radner used to say... NEVER MIND!!!
Is there any issue using a wide chain on a modern (1/8") chain ring?
I wouldn't expect anything serious... a little extra wear, maybe.
