prewar schwinn tandem

[volksboy57]

I picked up this old schwinn tandem yesterday. There are a few incorrect parts: front tire, neck, crank, pedals... I would like to narrow down a year for it, but for now I am guessing TOC-1930?? Please let me know if there is any information other than the Ignaz Schwinn family bike, and the 1899 schwinn catalog bike.

here is the schwinn family tandem

here is the scan of the 1899 tandem

I am not looking to sell it until I figure out what it is worth.

wow! What are your plans for it?

 

[volksboy57]

My plans are to put it in storage until I save some money and find some much needed parts. I will be looking for the (probably impossible) correct cranks, rims, tires, and possibly a better set of chains. These chains are extra thick! They are wider than a normal skip tooth chain.

Or... Perhaps I will sell the bike?

Let me know what you figure out for the front fork. I have a rear-steer frame and need to figure out a fork solution as well.

That's a prewar alright...pre WW1! Neat stuff. Gary

Here is the best picture for the front fork.

The head tube on this bike is a monster.

Before you put it in storage, coat everything in oil, especially any threaded parts. Time to start on the rust penetrating process while you wait.

That crank looks to be mostly complete. Just missing the 3 small bolts that hold the sprocket to the smaller circle. There would be lots of torque on those 3 bolts, probably broke off which is why the bike was barned. Look for grade 8 or stronger bolts at the hardware store.

Put the chains in a jar of oil for now, a few months of soaking may do wonders.

Thanks for the help. The crank that is on the bike is not right. I will need one of these impossible to find ones

Oh, while I am at it, I will need to find or make one of these forks

Hi, Do you still have your Schwinn Tandem? [email protected]

 

[volksboy57]

I still have the tandem. It is in storage, while I am so busy with work and life, that sadly I don't have much time for bikes.

 

[volksboy57]

just saw my bike's cousin on the other great bike website: http://thecabe.com/forum/threads/18...cle-with-original-paint-nickel-plating.94423/

also, I picked up the correct crank for the tandem! Now I just need the correct fork, and a ton of other stuff....

Nice tandem! You could use a more modern 60's -70's Schwinn tandem fork until you find the correct year fork, if the size is correct. The 60's-70's tandems have a 6-3/4" fork steering tube with threads about 1-1/2 down from the top. I have three Schwinn tandems, a 66, 67, and 79.

 

[volksboy57]

nice! I have three schwinn tandems also! This one, a Mini-Twinn and a town and country that looks like this with the drum brakes:

I have a lead on a 28" triple crown fork that is really similar to what should go on it... It will need to be modified to accept the steering arms from the rear steer tube.
