I can also redraw and convert to inch
If u like

Now i get the eccentric on the crank

[chris123]

I still got the centers from tunring the crank on it
I match them to the valve eccentirics
And voila. Regards chris

Ok i found em already
They are 6 mm off center
Its them

can you take a piece of wire and see if the openings at the ends of the round HP valve chest (1) are linked to the ones at the ends of the LP chest. (2)

If they are linked then that is how the exhaust steam from the HP cylinder gets to the LP chest via cored in passages around the side of the LP chest. It's a bit of a long route but would have acted as a bit of a reciever.

Hi jason and green twin
Its in inches now

Most of those shots with the wire are as I would have expected. It is what links the round piston valve chamber to the slide valve chamber that would be good to know. You might have to poke it in from either end and just get an idea of where it is going as the wire may not bend all the way round. Then measurements can be taken to sort out what needs to be made.

Getting there now.

Still not sure what the top and bottom slots of the five do on the slide valve. maybe hold the engine on end and pour a liquid down one and see if it comes out anywhere. Could just be a run out recess for the cutter if you were machining with a shaper

We will also need the diameter and vertical position of the round holes in the round piston valve hole.

Can you put a pair of digi callipers on a fe wof the round shafts as that will give a good indication as to whether the engine was built in imperial as your current sizes don't correspond well with common fractional sizes.

Yes inside admission on the piston valve and the image sin post #127 show a passage at the bottom as well as the previously shown top one so no need to have exhaust pass through the middle of the piston valve which makes life easier.

I have to go to bed now
The small hohles on the0.728 hohle
You mean?
I think its imperial
Metric weird neasurments tooo
The big cylinder would be
68.6 mm diameter
