Quite a contrast between that next to last picture and the box of parts shown at the beginning. Should end up being a beautiful and beautifully restored engine!!

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:

Hi Derek, the hoop valve will be connected to the Watt controller. I use five screws for larger flanges. (aesthetics) Usually for pipe 4mm 4 screws and 8mm 5 bolts. It's my style.

Amazing work Pavel....just two questions

1. was the Blue gasket material too tough and incompressible with scale torque?.....the Straw cardboard looks torn on the edge so was softer & more suitable?

2. Is this some sort of flared tube fitting in the second image?

Hi Pavel,

Great to see a governor actually controlling the speed of the engine when you varied the load with your fingers on the flywheel.  It looks like you were also able to alter the set speed with the spring preload.

Really excellent work, right up with your normal high standard.  Really great to see.
