    I'm not a DCC user, Larry, but there is a bit of room within the loco body and I've also removed the weight from the bunker (to ensure that I could glue the cab sections back together, although I will probably replace it with some lead in due course).

    The hills behind Plantagenet give some idea of the gradients all locos working back up the light railway face, when they leave Bethesda yard:

    Further progress on the 74XX chassis as of yesterday:

    Today I fitted the twin-beam compensation and finally had the wheels and axles sitting on the compensation system, as they are designed to do:

    Very nice work there CK, from your photographs it looks as though it will make the original look and run better.

    Further work on the 74XX chassis involves putting the brake gear together:


    Thanks to very clever design by High Level, the brake gear is designed to be removable for painting, maintenance etc.:

    I've found it necessary to reduce the width of the High Level gearbox, that comes as part of the kit. It's already quite a narrow gearbox, at about 7.5mm or so, but even that wouldn't fit between the brass bearings on the driven (rear) axle:

    I first of all removed one of the gearbox sides and re-fitted it about 1mm further inwards, using some 10BA bolts and nuts to hold it in the right position for soldering:



    When I was happy with the alignment, the side was soldered back onto the main gearbox and some additional strengthening pieces added:


    The gearbox now fitted!


    Now waiting installation in the chassis and test running etc.:

    Nifty work, Tim. Presumably this is primarily because you're working in OO here? I've done something similar a couple of times (for the same reason) in EM to get the hornguides in on my Gibson O2. Even then, I had to make the bogie compensation beam ride on the boss of the gear! Works though.

    Hi Adam,

    Yes, you are entirely correct, the problem only arises because this is being built in OO. If I'd known prior to soldering the hornblocks in place, I'd either have sought out some of Chris's slimmer bearings (I may even have some somewhere!) or at the very least, filed the normal-width bearings down sufficiently.
