I agree all New Worlds decals say seamless.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.
Thanks gkeep! PM me if you want more info on making some. Still holding together well after daily rides!!You pegged that strut problem. My teens Pierce has the same break in the back fender strut. I trapped the two piece with a wide washer layered with a leather one and it works ok but not as elegant as your solution. Hats off to you!
Thanks Sam. The split brass nipple idea would be nice for pressing on the non treaded parts of the tube. I used wooden vice jaws and long hollow bar lever arms to get it straight. You can see the pics a few pages back.The steer tube can be straighten, I've done so. A shop press and wood blocks would work best. But I've also used a vies and sleg hammer. Also a 1 inch I.D. brass nipple split with a hack saw also makes a good block for the vice
Hi Sam, thanks for sending more pieces of the puzzle on the frame construction. It does look fillet brazed to me. I can imagine "body lead" could quickly give it a similar look, but wouldn't it be soft like lead? Here's a pic of the BB. I'm no welding expert but it looks like fillet welding to me...Forgot to say. 41s new worlds were not fillet brazed as other schwinns, they were steel welded and body lead was used to give them the Schwinn look. If you turn the frame over you will see the weld as they didn't bother to body lead the welds at the bottom of the BB.
