…well the tap has been repaired.
The factory thickness of the tread is M4.5.
What I did is tuned away the old damaged tread on the tap on my lathe until it was 3mm.
Then I made a piece of M4.5 wire and drilled the inside to 3mm.


Then the tap is soldered into the new tread, and after the tread is cut to the right length.
And repaired is the tap…


Next was the missing fill cap.
Here a new fill cap needed to be made as well as new wire into the boiler.
For the wire an insert was made and soldered into the boiler.
And the cap itself is pure lathe work with brass and nickeled after.


At this stage the steam engine is actually serviceable.
But this engine is not complete with the water feeding pump.
Having an original on an other engine is a great help creating a replica.
In doing so, an old broken tap and quick cupeling where idle to integrate to this job.
The pump is semifinished now, but it starts to look good.
The replica and original…


And back to the work shop…
