Eddie, thanks again for the information it's been most helpful in enabling me to successfully get the loco turning over on c/air, with the help of your suggestions and a small adjustment to the off side crank it seem to have solved my problems so that's great news and again many thanks to you all those members who contributed to the forum.

Eddie,thanks for all your comments,since my original posting I have through other enquiries established the drawings I've worked to are correct so it looks like an error some where on my part. The shot shows the motion set with the piston set at the centre of its travel? You mention finding dead centres on the cylinders and say if I'm not sure ask, to be sure I'm doing everything correct an you clarify this procedure please,as you can see I've made an adjustable eccentric rods so they will be easy to amend the size if required.

Neil, Thanks for responding and the suggestion, I have a compressor with capcity of 24Ltr air reciever @ 80psi, would have thought that would create enough volume/pressure ?any other comments or thoughts would be apprecated.

Bearing in mind this is my 1st 5G loco with piston valves so have limeted experience , having followed Dons manual instructions on setting the valves and trying other meathods, testing on copressed air I cannot get the motion to turn through a complete revolution, it seems as if the valve needs more travel to clear the ports, so before I start looking at any major adjustments I need to know the dimesions I have worked to are correct . My drawing has 4.937" centres (check to place) on the eccentric rods?

The Don Young drawings in particular the combination lever, radius rod and piston valve have had some of the dimensions changed with no margine date or authorised amendment on the sheets concerned, this issue was taken up with Reeves who have no ability or desire to help, I also have the LLAS construction manual wich use the original dimensions.

I decided to follow the revised dimensions on these 3 items and completed the motion gear but finding it difficult setting the valves, before I pull all my hair out is there any one who has built this model that could advise the correct dimesions to make it work or any other info that might help
