Metropolitan Railway E Class Loco

Metropolitan Railway E Class Loco.







This rather handsome engine deserves representation in G3.

The frames of the E Class are made form 1.5mm steel with axles running in brass hornblocks and beam compensation.

The wheels were machined from 8mm ally plate with a square slot for quartering and the springs were engraved from 6mm ally.

I bet that looks great in real time

Very handsome. I must stop looking at larger scale models…

But two questions piqued my curiosity if I may.

You chose compensation over springing, and at this size/scale, I wonder why? (I guess, I’d have done the other thing!)

You've apparently got ally “tyres”, are you not concerned about wear?

How did you make the square slot, Mike?

I am more of a builder than a runner, I don't know how many miles you could run a model with ally tyres, but my guess wound be quite a lot.

I used to make wheels with steel tyres, but as I have to machine them from solid bar it is a lot of work, so that's why I when for all ally wheel.

I make a jig with two pins one for the wheel centre and one for the crank pin centre, the wheel is then fitted to the jig and clamped. With a 1.5mm cutter centred on the wheel centre you can cut the 3/16in square.
The quartering square is then true to the two centres
