How to Anchor a Drive Cog on a Flying Scotsman

John A asks readers:

“Can anyone tell me how I can anchor the nylon drive cog on my Flying Scotsman, as unlike the brass ones, the main shaft is not grooved and are held by 2 brass inserts. These slide when motor rotates and the engine remains stationary.”

    Try a drop of “superglue” liquid (not gel) on the shaft.

    John,
    Last year I found a new glue (to me anyway) when I was at Train Fest last year. Basically it is like super glue as it sets pretty darn quick but I have used it for everything It is called Sinbad Glue. It seems to hold just about everything including fixing my wife’s broken plates. I have used it on wood ceramic, metal and combinations where regular glue such as wood and plastic glue has failed. I have even used it on rock chess pieces to plastic washers neoprene type I think. You can get it at sinbadglue.net I would suggest also to get the primer with it as that will also allow it to adhere to material it won’t without it. One small bottle of the glue and one bottle of the primer has lasted me all year and does not dry up and get ruined like Superglue. It also does not leave that white residue on what you are working on and dries real clear.excess amounts are not necessary to get it to hold. Their demos at the train shows include metal to metal and how it holds. Clear plastic to clear plastic and dries as one clear plastic. You still have to get and hold your part in place fairly quickly and your hands also like to get glued to your parts. But definitely does not smell near as bad as Super glue. Try it I think you will like it.. Try to keep it off your fingers though. I have used it as much on my wife’s Ear ring and necklace repairs as I have used on my trains (but I have never tried it on an axle shaft and gear yet.) Newman

    I have successfully used Loctite shaft fit on an N scale locomotive. Forces not as strong as on larger locos though.
    Be careful as it is a liquid and as such may spread to places where you do not want it.
