Chain alignment issues with Schwinn Super Sport

I'm in the process of refurbishing my brother in laws 72 Super Sport and I've run into some problems that I sure could use help on. When I put it all back together, the chain is skipping when it's in small in back and small in front gears. You can see that the chain is on too much of an angle which I feel is the problem, but as far as I can remember,I put it back together with the same spacers and locknuts. I took it to the lbs and he said it must need a new set of gears because they must be worn out. Here's what I've done so far without any positive results.

I replaced the original 5 speed gear set with a Suntour 6 speed that was just as wide as the 5 speed. no change
I've adjusted the derailleur according to instruction from an old repair book from 1973 showing the exact Schwinn Approved Huret Allvit derailleur. no change
I replaced that derailleur with a SunTour 7 GT I had laying around. Had to remove the dork disc because the Suntour was too wide and it scraped. no change
I replaced the original chain with a Sedis chain. no change

I replaced the entire rear wheel with one from my Superior, and the issue went away. It looked like the chain was a little more in a straight line so that's why I feel it's the position of the rear wheel that's the cause of the problem. I have to admit that I did not ride the bike before I tore it apart so I don't know how well it worked before I started.

If someone could show in pictures, or just explain the rear bolts, lock washers and spacers,which ones on the drive side and which ones on the non drive side etc, I might see what I did wrong.

There's a different bike store about 40 miles from me that deals with a lot of older Schwinns, he even has a Schwinn Sting Ray museum, so I may end up taking it to him if I can't figure this out. Hopefully someone here will set me in the right direction. They usually do.

Here you go: SLDB 1969-70 Repair Hub Dept pg 111



I have many of these bikes with original components and have no problems skipping in any gears including small/small. Once you figure it out let us know what the problem turned out to be.

I believe you need 7 speed chain to work with the closer spaced cogs of the 6 speed Free Wheel.
Is the Sedis 7 speed?

Another thing to check is that your new cranks and B.B. taper are compatible

Great point. I put on a new KMC chain for 5-6-7 speeds, and it seems to be ok now. The kmc did not work though with the original cogs or derailleur. I'm going to take it for a ride and test it thoroughly before giving it back to the brother in law. Here's a pic of the bike.
