Lightly cemented the derailleur hanger to the frame. Friction shifting with a thumbie is excellent but I'll have to be cautious not to shift past the large cog into the spokes ! Perhaps a longer Limit Screw may be the answer? WSB, it's a new chain...KMC x8.93 7/8 Speed Chain

Yes and NO. I have a used worn 3/32 chain off a 10 speed which lifts off and on the 46 tooth Raleigh chainwheel. It does not fit my 1/8 cog on the fixed gear set up. Another used 3/32 chain does Not fit either the Chainwheel or the cog. Wear, is a factor. no doubt. thanks Ed.

A 3/32 Chain does NOT fit the 1/8 teeth of the chainwheel. This can not work. .

I am running the original chain ring with a 3/32 chain and cogs.
Runs smoothly with no problems at all.
I did have to remove the dust cap to achieve the best fit.
I don't anticipate any problems as I frequently disassemble and clean the hub and don't ride this bike in poor weather.

Regarding the derailleur hanger,there are two tabs on the rear side that keep it snug and aligned in the dropout.
With the wheel nuts tightened it absolutely will not move.
I cemented it on for wheel/tire changes with Gorrilla glue.

This is cool. I'd be tempted to drill a new hole to secure the derailleur. You could always slacken the cable to keep it from going into the spokes, but then you would have slack on the other end. I like your idea of a longer limiter screw. That would be a better, more permanent solution.

What kind of cement ? You don't mention if you are still using the original chainwheel or 4/32 Chain "? cogs must be 3/32 off a cassette.
