1779 Scale Model Naval Cannon
That bit of brass is 300mm long, 50.8mm diameter.
And it weighs 5.1kg (11.24lb). Watch this space for progress.

More Australian Wildlife
No, this is not about venomous snakes, sharks, spiders or crocodiles.
In common with a lot of Australian households we have uninvited guests in our house.
Our broom cupboard.
Brushtail possums. Harmless. A bit noisy at times, especially if there is a turf war caused by an intruder. My wife feeds them with tidbits of apple. And they love grapes. The baby in the first photo is quite tame, totally trusting my Dr Doolittle wife, but not so sure about anyone else. We don’t allow them access into the human areas of the house, and we are puzzled about how they access the broom cupboard, because there is a storey above.
They are a protected species, and it is illegal to trap them or harm them. We (SWMBO really) decided that we might as well encourage one family of possums and hope that they would fend off newcomers. After a few years of this family we are quite comfortable to have them living in our roof space and between floors. But we do need to fore warn human visitors about the occasional noisy screeching.

1779 Cannon Bling
Rings for attachment of ropes & pulleys, nuts and bolts, wheel pins and ferules, all made of brass in my workshop. Note the square nuts. Since this is a scale model, the originals would have been 50 x 50mm(2″x2″).
The round bits are flat head bolts which secure the rear axles.
Making the rings. 2.4mm (3/32″) brass wire is annealed by heating red hot, then wound tightly around a 3mm bolt. The resulting helix is slit to form individual rings.
The rings are flattened and adjusted using heavy pliers, then silver soldered to the threaded rods. The hole in the smallest ring is only 3mm diameter.
I intend to allow the brass to tarnish and darken. The bright new brass is, I think, a bit glitzy.
