While changing my LGB coaches to use my version of Raby's Knuckle coupler (http://www.thingiverse.com/thing:1989545), I found that very old LGB coaches were made with the hook and eye as an integral part of the bogie, and so cannot be easily replaced.
I therefore modified the bogie I had used on the 12 ton wagon, so that it now works with these old LGB coaches. I also redesigned the axle so that it uses 337 mm ball bearings. This should mean that the wheels /bearings have a longer life than the original metal on plastic design. The wheels can press on the brakes if the axles slide sideways, but if this is a problem, some washers on the axles should keep the wheels centred. Or you can imagine the scraping sounds as realistic flange sounds when going around corners!
The bogie is quite difficult to refit, as the back brakes need some very strong "persuasion" to allow the bogie to be fitted in the frame (see photo). However, they are quite strong, and provided that they have no weakness from print faults, they seem to accept the bending and spring right back.
