Bachmann Class 20 Conversion (2021 version)

[Ian FollandParticipant]

I have converted a couple of the recent version of the Bachmann Class 20 (part number 35-355 in this case) using Ultrascale wheels.

The design of the bogies has been modified since the Manual Sheet was produced hence the Ultrascale wheels as supplied are not a drop-in replacement, and the existing gear and bearings need to be reused (similar to the latest version of the Class 47 – Manual Sheet 3.2.6.(16a)).

The plastic spacing spigots on the back of the Ultrascale wheels need reducing (I filed them until about right, giving a bit of play), and the brake pull rods which run outside the wheels also need thinning.

 

A few pictures:

As supplied, 00 wheel sets; Bogie moulding removed; 00 wheel set in the wheel puller I use, bought on Amazon; one EM wheel set fitted; bogie moulding before thinning the brake pull rods; finished article (just some cleaning up to do)
