Made a fair bit of progress. the plunger pickups are fitted fully with a blob of araldite.

the powerd part of the chassis goes together very well and with the slaters squares axle ends make quartering simple and effective.
one thing i would like to see in the instructions are more images ( i am going to send some off to add )
I have found the helping hands a great item to assist when soldering.
I have got the brake shoes put together and will be adding them this week

i will repeat how much help Pete provides its fantastic
