Another David Auld marine engineHi all,
I haven't been steaming much lately because of work. However, my latest TradeMe purchase arrived and it has me steamed up again.
Another David Auld marine engine. Made in New Zealand. Not sure of the date on this one. It has a different safety valve to my other Auld engines.
Despite its unapealling colour, it is very well made. None of the pipe work is soldered - all is threaded and screwed (like this on all of my Auld engines).
The bore is huge on this one!
Here it is beside my other Auld marine engine
Time for me to start boat building  I can't wait for the Easter break

Nice.
It looks like its time for a New Zealand fleet I think.

Stitch, if you build a boat to go around that engine, you might consider a battleship or aircraft carrier...jeez that looks like beefy construction to say the least...love the glow of the brass in contrast to the battleship grey.
Seems a wave of boat building is upon the forum of late!!

Those look like real quality engines. Is that a valve on the oiler of your new one or just a filler cap?
Seriously nice stuff

Thanks guys for the comments. I think I will start with a small boat for my SEL engine and work up to something for this monster.
I have just fired it. Very smooth, but what a beast. There is a lot of torque there 
The inside of the firebox is lined with some kind of cladding (I suspect asbestos).
Mr O, it is a valve and gives surprising good control over the speed.

They are two nice looking engines, well done.

You said there isn't any solder, just threaded, are there leaks?

New and amazing to me, Stitch. He must be quite a builder, quite an individual thinker.
Most appealing and worthy of big boats to come.
Looking forward to seeing them float some day!

They are fantastic Shaun 
Very very nice. I really like the idea of a valve for speed control. Mine needed that as it was too fast.
Can't wait to see what boat you build

That white firebox might have a reason: it radiates less heat than a darker coloured firebox--saves heat for the boiler and saves the hull the suntan.
heated, light coloured objects tend to throw off less infrared than dark bodies.

I have a small number of Auld engines. All (apart from the mobile) are superheated and make use of threads. I presume the steam pipe is soldered to the boiler but I can't tell as Auld seemed to use a type of double skin construction and I am not game enough to take one apart Suprisingly, none of the threaded joints leak, even after extensive steaming.

Auld had a general engineering firm and did small runs of locos, stationary's, verticles and some novelties like a steam crane and a lauch. Cranko, a forum member, has a crane and a launch. They look fantastic.

If done properly I would think that threads would be a better way to do it, it should be a lot easier to work on.
All of this boat talk, I am fighting not to succumb to the temptation.

i'm not sure about the general engineering bit . I believe from 1966 onwards he was focused completely on steam toy production
