Looking at this very simplistically, just take the wheel off the right hand side and fit it to the left hand side, and all should be well. In other words, the wheels are identical. (Thats the way I reckon it should be, and I am sure someone will correct me if I am wrong! Oh, and what loco is it? alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. ----- Original Message ----- From: "Tim Rickard" <the_viffer@xxxxxxxxxxx> To: <modeleng@xxxxxxxxxxxxx> Sent: Saturday, December 04, 2004 7:20 PM Subject: [modeleng] Balance weights I'm just about to fit balance weights on a loco. I've got a photo of the right hand side of the prototype. The coupling rod pin is at 12 oclock. The balance weight is at 3 oclock. I know the crank pin is at 6 oclock. Where does the left hand weight go relative to the left hand crank pin? MODEL ENGINEERING DISCUSSION LIST.
