Hiya Simon ,did you ever do a video of Abberbig ?Mick,
I did a similar trick on all the locos on Aberbig. A strap and pin bonded to the bogie outside casting; a 10BA screw attaches the strap to the top surface of the bogie inner. Two pins to locate the outside correctly. Photos if you want![]()



I do have a plan for one of the three to rebuild but just need to check some drawings. These three will all be mine
. 
. That'll get the chattering classes going.

I may go back before I do the blue and preshade the covered panels at the #2 end by the doors and a bit more around the headcode boxes around the gutter area.
This is the first time I’ve seen pre shading on a railway model. Aircraft and military modellers use pre shading with great effect. Cannot wait to see the end result. Well done on pushing the boundaries Mick.Class 25 body already for top coats, finally got around to filling the water hatch filler steps and add etched blanking overlays and fit a slightly larger 3D boiler vent, also filled some joint gaps and pre-shaded.
