Romulus 0-6-0

I am building the above loco and have reached to point where I need to quarter the wheels but I cannot find anything in the drawings to tell me the positions of the crank pins. If I am sitting behind the engine with the left hand crank pins at TDC where should the right hand crank pins be, 90 degrees forward or backward ? Also, are these positions standard on all Locos?

Thanks Pete

Pete,
Standard railway practice is the R.H. crank leads in forward motion, ie 90 degrees forward.

Regards Terry

Terry, Many thanks for the swift reply I knew there had to be a simple answer. I will be on the job tomorrow.
Cheers Pete.

Agreed that standard practice is right hand lead - but I've never found any good reason why and I know of at least one class where left hand leads. The main thing is that the angle is close to 90 degrees - it doesn't have to be exact BUT all axles must be the same.

I originally made my Romulus with a left hand lead, for no reason than I knew no better. A recent axle change has lead to her changing to right hand lead, because I am told that is what it should be!

Thank you all. I now feel educated in the ways of quartering.

Many thanks Pete
