A further, small, milestone has been reached since the last update - the first bogie has been wired up and tested with an old Hornby controller. As shown in the photo below, it all works together!
I did have two swap two wires over, as one motor was turning the opposite way to the other two (I think I must have had the motor the wrong way round when I soldered the wires on), but that was easily corrected.
I've also added the cosmetic axlebox covers, cut from the kit sideframes, so it's now really starting to look the part. I've yet to add pick-ups, which will hopefully be to all wheels, if I can fit them in, and the various kit detailing parts such as the brake gear, brake cylinders and steps. I also need to move the brake hangers, on the end of each bogie, out a touch as well, which is something I hadn't even considered until I was chatting to someone at the Mark S7 meet a couple of weeks ago. Apparently I should be able to cut these off and reattach with butanone. I was given a better method for use on the next kit that involved chopping up the end cross-members and gluing together, but it's a bit late for that with this one.
The top view shows that there isn't going to be an awful lot of space inside the frames once all of the detailing parts are added:
The bogies will be connected electrically to the rest of the loco using disc drive connectors, which are the ideal size and have 4 pins - 2 track feeds and 2 motor feeds from the decoder. Following the trials with the Hornby controller, where the motors were run at full power for some time without getting hot, I think I can get away with wiring each bogie in series, then connecting both bogies in parallel. I'm not entirely sure what this arrangement will do to the decoder, it has been suggested that it may get confused, but I guess that there is only one way to find out!
