I reshaped the frame stays and re-centered my lacing a bit. I swapped a couple jamb nuts, and it all finally fits!


Now I need to reshape the dropouts so I can tighten the chain. But I did get out and rideit, sloppy chain and all, and the gears were okay.

I used the old tourniquet method to bring the stays in a little closer together.

First ride with the new Sturmey Archer hub.



The chain is too sloppy.


She gleams!

I decided to put the derailleur back on, and lock it in position to use as a chain tensioner and guide. It works pretty well but is really black & ugly. I do have a silver one somewhere that might work but it’s not in great shape in this one is like new.




I was really happy with the way the new hub works now that I got the chain to quit skipping. You can really stand on it in top gear with no hint of frailty whatsoever.


I had to lock the derailleur in place with a scrap of cable, so it acts as a chain guide and is always in line with the rear sprocket.

I couldn’t deal with that black monster very long. Yesterday I built a new tensioner from a used derailleur. I drilled the rivets away and removed this stuff.

I ripped up this funky little bracket to get the bushing out.


I turned the flange off of it, and then pressed it into this Shimano adapter arm.


I drilled that little hole for the spring to seat.


So here it is on the bench.




And here it is on the bike.



It needs some cleanup and adjustment, but it worked the first time!


I still don’t have a front derailleur, and I have to move the chain by hand, but I won’t change from high range to low range under normal circumstances.

Thank you @cheesy. It’s much easier when you’re working with nice parts.


I didn’t know if that was going to work or not. It was a total blind experiment but I was guessing that I could somehow get it.


It was a little bit tight to get a perfect adjustment where it didn’t growl, or skip, so I drilled out the other hole and chopped off the hook and thus moved it as far from the sprocket as possible. (It was hot enough out that I decided to work in the office.)

The chrome looks bad because that’s the backside of the original bracket hanger and never got polished before chroming.


It doesn’t matter that much because it’s going to rust where I ground it off anyway.


This is a much more satisfactory arrangement, And now that is quiet and there’s no skipping. That works well on high or low range.


BUT, I should TIG that bushing in place before it gets loose.

I finished lacing the little wheel that I stripped.


It needs some final buffing, decontamination and clear paint.


I’m still trying to come up with workable shifters for my Mongoose bike.
