I am finding it hard to find a set of Jewellers screw drivers which includes some hexagon ones small enough to fit the tiny hexagon screws used on the crank pins of Hornby Locos to hold the crank rods on.
Anyone have an idea where to buy a set. I did have one which fitted the Hornby screws but I have lost it somewhere and have been struggling with pointed pliers, but they can slip and scratch the finish of the metal surfaces.

You need a nut driver for the crank nuts/bolts. 2.5mm size fits newer models, older models may be a different size. You can get them from Expo Tools or your local model shop.
Expo Tools - https://www.expotools.com/cgi-bin/ss000 ... TION=Go%21 I think Hornby do a double ended version too, or at least they did.

Thank you very much Roger for that info. Most grateful............John

Make sure you get a nut driver, or nut runner, not a hex driver. Hex drivers are used in a similar way to Allen keys.

PS Looks like Expo no longer list nut drivers.

Loads of nut spinners available, ebay for instance. Hornby make one for crank pins.

For example.

Thank you, Brian but I did not know they were called nut spinners (was looking for Jewellers screwdriver sets) and that is probably why I could not find them. But rog has put me on the right track now. Thank you......John
