After the bogie coach I thought I'd try something a bit smaller and more complex. The main problem with T scale wheels is that they are designed to be held in bogies and the bogies have points that go into the wheels not pinpoints on wheels. They are also of course very small.

For this wagon I drilled 0.4mm holes into the centre of each wheel (down the existing dip) and superglued fine wire. The next problem was bearings. After about five failed experiments I hit upon the answer- N gauge handrail knobs, with the loop for the wire acting as the bearing.

It runs, although its a bit rough. I got slightly too much glue on the rods into the wheels seems to be the reason so I know next time what is needed to get smoother running. Then again after the number of obscenities emitted I might build a bogie wagon instead !

Needs more paint and weathering but it'll pass with a bit of dirt.
