Loco wheel quartering

[Alastair MacphersonParticipant @alastairmacpherson52003]

I am building my first steam locomotive and have reached the wheel-quartering stage. I have read that it is usual for the right-hand crank to lead. My question is; with the RH crank at IDC, should the LH crank be up, down, or doesn't it matter which?

I don't think it makes any difference to the running of the loco, but with the RH piston at rear DC, the LH crank should be down.

I think that's correct!

Thank you Clive; much obliged.

It matters if you are a rivet counter, but beware although MOST locos are as Clive describes, some are not!

Southam is a diesel not a steamer, but the cranks are definitely 'the wrong way round' on the real thing.
