No, I've not been shouting that word in libraries in homage to Dick and Dom, but I've actually started work on the springy bogies of 415.

Quite a productive weekend has seen me prepare the 42 teeth gears for fitting onto the axles and make a start on the axles themselves.

The gears originally had a 2mm hole in the centre. I enlarged these by drilling 3.5mm, 4.3mm and then reaming to 4.74mm for an interference fit on the 3/16ths axles. Which brings me, neatly, to the axles themselves.

The original plan was to have solid, one piece, axles, but further thoughts turned to how I was going to set the back-to back measurements effectively, with all of the traction motor gubbins in the way. The solution is to have the axles in two halves, which will screw into one another, allowing for adjustment.

One half is 23mm long, drilled 2.5mm and will be tapped M3. The other half is 28mm long, but has 5mm turned down to 3mm, ready for threading M3. Once the axles are assembled, I'll see how the threadlock holds, if it's not sufficient I'll drill through the two halves and taper pin them.

Next jobs are to thread the spigots and tap the holes in the other halves, before drilling and reaming the wheels to 4.74mm.
