hammer:
The fly wheel, I had picked up a piece of 2" brass rod at the scrapyard (£3) recently. It had the centre bored out at one end, I also had a short piece of 1" rod.  Parted off 1/2" and opened out the bore and pressed the 1" rod in, then did the same for a 1/2" rod, this saved a lot of swarf.  :cartwheel: This produced three ratio for the take off belts. I intend to make a well with a pump, a hammer worked off a cam and a dynamo with a lamp.

hammer:
There's more today. fitted the bands on the boiler. Found some 3/32" + 1/4" too thick really but it looks OK. Bent it by hand working around & around until it fit on the boiler with a 1/4" lap. Filed a tapper on opposite sides and  :zap: soft soldered together. Join will be behind the steam pipe.   The lower band has a plate over the fire hole to protect the timber. Polished & pushed on the acrylic varnish (this will not burn) hold them in place. The wood in the last 2 photo is the base, just stoping boiler rolling.

hammer:
The pipes & the patterns (solder) A change this time the exhaust goes up the chimney. After saving making swarf yesterday being wasteful today. Boring out a bronze bearing for the burner. In the photo small bottles for the meths marked to the individual fills.  Finally the two models, won't be boring you any more. But I may post a video of them both working.

tvoght:
That's a nice pair. Clearly brethren, but each with his own personality.
