Good to see the beautiful work progressing. 

Is that a SS boiler in progress as well?

Interesting angle of engagement for the grub screw Pavel........

1. is the main shaft a replacement?
2. will you make a flat or dimple the shaft to allow the grub screw to engage at such an angle?
3. the cylinder appears to be 50 mm........or is it 2"?
4. not usual to see Continental/European grub screws with a screwdriver flat......so is the original English?

Hi Derek,

the screw will touch on the shaft, where there will be a small area, the original steam engine is only a bronze cast of the cylinder, everything else I do from my drawings

Pavel.......a question......

The valve on the right side appears as a rotating spindle [globe valve or needle valve with the bonnet bolted to the body] & typical of an Isolation Valve which you have shown on previous builds.......

The valve on the left appears as a rising spindle valve with the bonnet screwed into the body, [and actuated via an external mechanism bolted within or to the connected hoop ?] so if this is the case is an early version of a speed Control Valve?

We also see you have changed from a 4 bolt pattern to a 5 bolt pattern.........any reason for this?  :shrug:

Derek  :cheers:
