Hercu-stein

Cleaned up my '65 Hercules frame and I grew attached to it so the next build will be a 58' vintage S.A. Dyno-Hub front, 69' Sturmey Archer 5 speed racer with fixie style chopped and flipped 10 speed bars.

Before:

Here's a mockup with a 58' Dyno-Hub on Raleigh pattern 26" x 1-3/8" rims. The rear wheel is temporary while I refurb. the five speed and assemble a wheel.


Fred get out of the picture!

That's better.

More parts!

Scored a bell crank for the 5 speed from Harris Cyclery in MA. Great sturmey source.

Her-cu-matic shifter. I'll run this for the right side and a derailuer style shifter for the left. Sheldon says thats the ticket!

My dog does the same thing whenever I take pictures.

Cool! I like the simplicity as of now. Did you say that is a Dyno hub? How common are those? It looks identical to my unmarked drum brake hub which finding parts for has been a nightmare. If you could pm me several pictures of the drum brake hub (the axle, cones, and pad assembly) that would be a huge help. Great bike!

A Dyno-Hub is actually a hub based generator that powers lights. Sheldon Brown's site that has a wealth of info on Sturmey Archer stuff, both Dyno-Hubs and drum brakes. Try the Sturmey Archer site also, they have a great history section full of pics and exploded diagrams. Post some pics of what you have, this site is chuck full of vintage bike geniuses. I don't know much about drum brakes except that I want one!

Heres some pics of my 61' Raleigh equipped with a S.A. Dyno-Hub. There really cool and practically frictionless. The wires attach to those 2 silver bolts in that dark section and go to the lights.

BTW, I like your quote. Not many realize were a Republic, not a Democracy.

Sorry, I saw one side and it looked just like my drum brake hub, so I assumed it was. Thanks for the response, I have never seen such a thing as a wheel hub generator, that's a great idea. I will definitely try the SA site and Sheldon Brown's, thanks for those ideas. I should definitely post my problem here as well, someone out there probably knows exactly what make hub I have and if parts would be available anywhere. My axle is way too far gone by to fix... I am considering having a new one and new cones machined. (I am not entirely sure that's possible unfortunately...)

Thanks for the compliment about the quote.

Finally loosened the ball ring on the five speed hub so I can refurb it. Built myself some helpful tools in the process.

In the homemade hub vice:

The homemade spanner:

Works great:

Leverage Big Wrench style:

Cool tools. Can we have a full shot of the big wrench?

Scored a bell crank for the 5 speed from Harris Cyclery in MA. Great sturmey source.

was that thing really $18? my local bike shop sells em for $4 (also a great resource for sturmey stuff -old or new)
i'd hate to find out what he charges for the hubs themselves

great project, which model hub are you using?

 

[ej599]

I'm running (hopefully) a 5 speed 1969 Sturmey S-5 hub. The bell crank goes on the left with an indicator chain on the right-like a 3 speed. Here's a pic from the S.A. site.

I assumed it was kind of rare as I never saw one before. But if I paid $18 fo a $4 part then here's my new name tag!

What's the name of your shop?

Length: 25"

Rusted fork nuts tremble at the site of this thing.

Bikes looks to have a "slight" rake, nice. Really glad that you share your knowledge, of this style of bikes and hubs. Don't know if I'm ready to tackle my 5 spd hub (like yours). And If Fred gets in your hair, I'll take him for a couple of weeks. :wink:

 

[ej599]

Well, got the bars cut, got a spoke cut to replace the one broken on shortside of the dyno hub. had it done at Clark Cycle in Essex. They have a spoke cutter there. good place. I also got the shifter functional and mounted.

I also built a seat post out of 304 Stainless Steel. A shim also.

22 tooth sprocket, it's hilly out here.

Inside the S.A. 5 speed.

The dreaded pawl springs.

These pinion gears actually have 'timing' marks on them and I discovered if you don't have them aligned correctly the hub won't spin.

All reassembled and ready for a hoop. The 3 speed side works and the low-high side appears to.

 

[ej599]

More progress. I actually unlaced a perfectly good 3 spd. wheel to get this hoop. I figured the 5 spd. was worth it.

In order to test the 5 spd over and under drive I had to work the 3 speed side. This worked good.
