Hi Cabe Lightweight Schwinn Folks,

I recently inherited my grandfather’s 1941 BF Goodrich badged Schwinn New World. SN# H69537. I’ve been reading about it and learning how its built as I take it apart. I’m really interested in getting this bike running again to ride with my kids. It looks really ratty on the outside since it was stored in a shed in Pennsylvania for the past 70 years or so but the bearings and races all seem ok.

At some point the right pedal must have gotten stripped and my grandfather welded the pedal axle to the crank.

To get it in the shipping box the guys at the bike store in PA cut the pedal off.

I’ve been looking at pedals on eBay and the set of Torrigton 10s I was watching just sold for $46. That seems like too much money for me since I just need the right axle. All the other parts look fine in my pedal assemblies.

Was hoping to find just a crank too but most eBay listings are for the whole crank and bottom bkt assembly. There’s an older looking set from a Hornet DX bike on eBay right now. Are most old cranks treaded the same and have the same spacing?

Thanks for any advice you can share.

The bike was painted with red spray paint and is pretty beat but I think it will be a very cool rat rod and the sentimental value for me is huge.

The fork tube that runs through the head tube got bent at some point. Also there were some rogue ball bearings that were loose in the head set and over a period of time they badly scarred the threads.

Is this saveable? Can I straighten the fork tube and re-thread the top so that it can be properly adjusted once straight?

Hi GTs58. I can see them on my screen. Maybe they’re still loading or need approval since this is my first post.

The hubs are New Departure with a D coaster in the back. Seem to be in good shape too.

Hi GTs58,

I had legitimately messed that first post up. I think the pics are there now. Should be better now.

I've had luck straightening fork blades. I used a bit of heat from a bottle of Mapp Gas so that they would bend up by the crown. You kind have to just eyeball them because of the taper. Remember to straighten them side to side also. Key for "no hands" riding. You can draw a center line of a piece of plywood or paper. Next, draw two more lines parrelel to the center line that is the width of the fork tube. Measure your front hub axle width and set your blades up so the axle rides dead center. A high end bike shop should have a huge die that will clean up the fork tube but the messed up threads below the head set should be a problem.

Great machine. I think that is one of the frames that uses Cromoly thing and is hand brazed.

Hi Beach Bum III,

Yea I think you’re right. Fillet brazed seamless drawn chromoly.

I’m guessing I can re-thread the head tube with the correct die. The threads at the very top are in good shape so the die will be lined up correctly when it hits the scarred section. Wonder what the thread size is?

The steer tube threads are 1"- 24 tpi https://thecabe.com/forum/threads/schwinn-head-tube.53640/#post-317497

I haven't come across one that looks as nice as yours. lol Hope you can clean it up and salvage the fork.

The Superior and Paramount were chomo and I'm thinking the New Worlds were seamless steel.
