Wow I never knew there was a modern size of rim that was the same size as a 26 inch S7. Crazy. Bike looks cool. Like what you got going on with the gears.

I did forget to mention that I flipped the dogbone so now that when the bars are in the dropped position it faces up
(it seems to work best that way since the drop on the bars is longer than standard)
and faces down when the bars face up
(because the adapter stem sits fairly high up already)

Yes if it wasn't for visiting Sheldon Brown's website I may have never noticed that the s7 tires are the same as the 650c rims
https://www.sheldonbrown.com/tire-sizing.html
but just because it looks good on paper didn't mean it may work in practice
so i was still taking a chance that it might not have worked

Same with the gears it worked on small scale with the coaster brake challenge bike I am building but I wasnt sure it would work on a larger scale
most of those small scale test the tooth count difference was about 15t not 45t like this bike has


Your 'tooth count' chart reminds me of an old musician's joke; and especially close to home for me as I'm a 'player'.

Q: "What's the difference between a violin and a fiddle?"

A: "The number of teeth in the player....."

OddJob, Today at 4:20 P

Yes I have heard that joke
My question is does that mean a player with more teeth than normal play a Stradivarius
and what about no teeth would they play a harmonica
no wait sorry I mean a kazoo
 
Not much to report except I have found some fenders for the rear
but I need to see which style I like best for the build

I did have to shorten them

And I picked which quick release clamp for the coaster brake arm to use
36142582585_d7c1236940_b.jpg


I did have to widen it a little bit
The few threads that are sticking out pat the nut are what I ended up filling down in order to make it work

I am guessing the rounded fender will look best, but the squared one has cool character about it too.
Tick Tock - 14 days left
 
I am having trouble picking a fender that works
the squared one looks to narrow the rounded one doesn't fit right either
and i can not work on the most of the sheetmetal work because it needs to be attached to the fender

Fortunately there is one more cycle swap to look for fenders at


the rest of the time I have been working on a seat post
but most ideas are not working out quite right

Do you think you might have the time and materials to widen the square fender?

I know welding that thin of metal sucks, but it might be an option. Infeasible, but an option.
 
ok I guess 1/2 of my post didn't go through

Anyways
the rest of the time I have been working on a seat post
but most ideas are not working out quite right

Then I realized a possible solution had been literally staring me in the face

Schwinn exercise handlebars
35799057090_d5eb96ce3d_b.jpg

Older version on the left / newer on the right

These things suck for using on bikes
but after cutting them up
35799056620_64e061c72d_b.jpg


They make good custom 7/8 pre bent chrome seat post

I just need to get it mocked up and make the final cuts

Falstaff

hard to say I will have more of an idea after this weekend
right now finishing the seat post
making a number plate (aka a mini tank insert)
and fitting a front headlight take priority

Hmmmmmm, you have me curious about that seatpost shape?
 
Wanted to show off the new seat post in both orientation
but apparently there is a blockage so i can not show it all the way down in cruise mode
YET

Also for anyone curious about why I didn't cut up the other exercise bars
Some of you may remember my earlier build of trying to use as many schwinn exerciser parts on my mid 50's schwinn (before photobucket blocked em all)
Others may not

So here is a bit of a reminder

Not fully finished since my time has been dedicated to working on B/MSR #305
but after the build off I plan on getting it completed
 
Lots of scores while looking at the swap meet and through some of my parts stash

Found a schwinn fender that I think will work best
It was probably off a bike that had s7 tires
so that might be why the size fits better than my other fenders

Quick mockup

Also found a set of wald hbars that closely match the hbars I originally was going to use

I put the dogbome on the wald bars
original ones I had in the pics are without it

One of the other thing I found was an alternative seat and post in my parts stash

Turns out I couldn't get the post past 1/2 way down
almost like the whole tube narrowed

So instead I found this messinger seat to use
36159713051_c481a62e75_b.jpg


And a (I think mtn bike stem) that I bought a while back at the local co-op for its long bolt

35458485464_81695fd060_b.jpg


Turns out it seems to show signs of being a good replacement post
with some modifying

Stem (i mean seat post) is cut, drilled and ready for install

You've been busy with this one. I like how it's all shaking out.
Love the fender
 
While working on a few ideas for the headlight

I came across an idea that involves using a murray monterey chainguard
35500655984_5220f8a6e2_b.jpg



First cut it in 1/2
36336475265_78acba79e8_b.jpg


remove the front
36336474465_2a6ecc25bf_b.jpg


Angle cut the longer ends
35500657214_735755cdf5_b.jpg


then keep trimming
until both pieces can be sandwiched together
35500658374_b85dc4f9d7_b.jpg

36336476065_43e0e1402d_b.jpg

more trimming
35528002783_fa07563aae_b.jpg


Anyone care to guess ant what this will become

I will post more about it tonight
 
That murray monterey chain guard will now be the mini tank insert / aerodynamic number plate
(that is why it tappers to a point)

Mocked up in cruise mode
36342225215_4345f080f0_b.jpg

still needs mounting brackets but wanted to see how it looked on the bike
could have made a longer one if I had another murray chainguard
but who keeps those things
seriously
I have discarded of at least a dozen of those things
 
Had a minor issue with the seat
It wasn't staying in place with with the "post" kep angling back
However it looks like I can make the original seat that i was using which was the Ideal leather saddle


Fortunately the ideal saddle had the original extra adjustment extensions that i could make work on the post
the lower clamp is for when I make the extra post brace

Also found a paint/color that looks promising
36209446652_8b844db7b9_b.jpg

backside of the number plate used as a test pain

The color is a has a bit more brown than what is shown in the pic
looks a bit like the color of these
NHGRI-3910.jpg

Kinda fitting
I think
