4 forum posts	Hi there Nick,Very kind of you to reply.I know nothing about locomotives but a little about steam engines.I have built the steam engine between 2 side frames only, no wheels and nothing else. I test ran on steam from a stuart boiler with limited success but only after reverting back to my orginal position of the slide shaft pivot point,(ie 6mm higher that the position shown on the orginal drawing).I think my problem is the out of balance flywheel although I have several balancing holes.I am now working on the wheels hoping that I can balance the flywheel more accurately.As for your first question I do not know how to answer it. Regards Douglas.

Continue with the chassis and add the wheels, this will smooth things a bit, but it is not until the loco is on the track and under load that you can really tell if it is set up right. With the reverser set towards the middle in forward gear i.e. short cut-off. it should be possible to set the valves so that front and rear port openings are equal.as the crank is rotated. As far as I can tell the revised position of the reverser is right so if you are having to set the pivot 6mm higher sounds like something is not to the drawing. The test model I am building for the series in ME runs OK as per the drawings. Cheers Nick
