happy to have an appropriate chainring for my project but this spacing for the engagement pin is a new one on me.
none of my cranks fit!
so... while I search for the correct cranks (hint, hint) I'm wondering if the spacing of this chainring indicates a certain time
in the evolution of Miami bikes.
all of my cranks have a spacing of 1 3/8" on center. this one is 1 5/8" on center. (or 1" from the edge of the axle opening to the pin opening. hopefully my crude markings make sense)
am I over thinking this ? am I crazy ?
answer the second question first :p

In addition to @redline1968 's proclamation ...
some rings have a small, drive-pin portal ....
some do not.

Building a Miami from parts acquired from
different places is not for the impatient.

The manufacturer was once one of the
largest producer of an array of wonderful
bicycles and motorcycles. Today, every-
thing Miami-built is elusive.

Have observed more Racycle stuff over the
years .. but even those fall numerically-short
compared to Davis relics.

If you're looking for a non-frustrating teen's
machine to build .. or just to find a few missing
parts to add to a machine that needs limited
attention to get it ready to ride .. or, maybe
just display ... stick with Westfield and Schwinn.
Great Bicycles ... plenty of availability.

But .. if you are steeled to walk the labyrinth ...
and are guided by a patient soul ... go ahead ...
ride the Lightning that Miami built.

I never thought finding “the right” parts would take sooooo long! Now that I have most of them, it’s just a matter of paint, learning how to pin stripe, engraving logos back in, plating and re-assembly.... I had to find handle bars, Hager nuts and bolts, the right hubs, rims... even though the bike was already “complete”... yeah, I’d love to find a set of my “dream” pedals but they are not going to hold me from finishing this up!

What dream pedals might that be?

I heard tale of a set of pedals that were attached to a bike at the ML summer swap that had Miami stamped in them?

I was there a day late to see them. Heard that the buyer tried to buy just the pedals but the seller wouldn't take them off of the girls bike they were attached to.

1. Not sure.
2. Re-measured a junior set today at 2" c-c --- for a ~1" crank, and ~3/8" drive pin hole, that would be about 1-5/16" metal 'landing' between holes.

Thanks, learning about Miami & Merkel Minutiae the hard way.
Miami 1-5/8" (unique);
Merkel 2" (among others);
Both with oversize crank/cone thread diameters, (ugh).
@Archie Sturmer

Young man ... your testimony, above ... is a partial demonstration
of the difficulty of locating replacement parts on a Miami-Built ...
or going into the business of building (from found parts) a full-on F-M.


Any reader that truly believes that scratch-building any Miami machine
is a walk in the park ... well, let's see you go for it -- then tell us about
your experience. No Need To Report All Those Times Where You Cried Like A Baby.

I was thinking, when typing "unique" there might be others...
Crescent sprocket hmmn.jpg
Not sure about this one, 1-5/8" C-C with a 'spider' and 5/16" pin hole (or metric), and common 15/16" diam. shaft; might be a (pre-Pope/Westfield) Crescent?
Almost there on the Flying Mackerel tribute.

Found the frame without any badge holes.

Still looking for those $50 black & chrome decals.
