Ambitious project - model of Irrawaddy paddler "China" in 1 : 48 startet

[kno3]

Very nice project. Could you tell more about the new teflon pistons? How do they perform?
Are the valves also teflon?

[Hankwilliams]

Former problems gave the piston valves (not the slide valves or the pistons themselves) made from brass, bronze or another metal.
After a while of running the material wear out, result was  untightness of steam and therefore a loss of power.
I think, this problem is now solved. Teflon is a soft material, which is tight fitting at the cylinder and it is of long duration.
As far I know, Mr. Regner (who died in July 2013) was given a patent of piston valves in 2008.
By time I can`t made a test run with this engine, because I`m waiting for some tubes and fittings, but I expect less steam consumption and more power.

First steam up at 14.05.!

Last week I made a first steam up. Because I still don`t have a boiler for the boat - I `m waitung for brass and copper parts -  my steam plant with the outside boiler seems a little provisorically, but the main thing: Engine and boiler are working well after some minor faults at the beginning.
As I expected, power and steam tihtness of the Regner 12/36 with teflon pistons and slides are much more sufficient than in former models of the engine.
In the last pictures you see the installed water condensor and the boiler feed pump.
I hope, that I ´ll get soon the boiler parts so that I can finish the whole steam propulsion. After this I`ll continue with the superstucture.

Hello ;
Beautiful mechanics!

[derekwarner_decoy]

Very tidy Thomas..... ....the steam inlet & exhaust manifolds you have constructed are ascetically very good and functional over smaller individual tube spools....the engine looks superb  

Just one question, you appear to have lengthened the boiler makeup water pump drive shaft from the eccentric to the actual pump plunger shaft by say 100 mm, will this cause any deflection with 3 Bar against the pump plunger? ......[the image in the Regner catalogue does not show what sort of length for the length of the pump outer support bush]

Another question if I may  ...what type/Brand steam regulator have you installed?..is this the valve handle?

I cannot make out or understand the functionality of the Regner 'Steam Diverter valve'? ..funny name for a regulator] and it does not appear to be ANTON...could it be Chinese from Jin?
 
I see you have one of those quartz tubed lubricators from Winfried Niggle .....extremely functional [with the view of the oil and also beautiful] ........... Derek

[Hankwilliams]

Hi Derek,

yes, I`ve extended the lenght of the plunger rod by 135 mm. I don`t expect any deflection, the rod is strong enought.
I use the Regner steam regulator, may be it`s not the present model, it lies in my little stock for years.
The Niggel lubricators I`ve also used with success for my paddlesteam canoe "Fultons Folly" - see April or May 2015.
I hope now, that I will get soon the materials for the boiler.

Hi friends and neighbors,

in the meantime - waiting for boiler parts - I made the stanchions and the support of the upper deck. The brass U- profiles are 5 to 4 mm.
It´s not very difficult to solder it to the stanchions. Refined work will be still made. The later deck over the engine and boiler area will be removable.
In my opinion now the built gives a little  more impression of the finished ship in the intended future.

Nice work Thomas

[derekwarner_decoy]

Hullo Thomas....

Just digressing, you appear to have an abundance of natural morning light in your work area which is  great   ....[are they Dormer type window panels set into the pitch of the roof?]

I did not know the name or location for Munsigen and checked Google......so does your work area roof pitch face south to catch the sun?


But I also do not know how you keep those fine carpet coverings so clean  ...............Derek

Hi Derek,

for me the electronic communication possibilities are always and again still incredible - to interchange with people of the same interests living so far away.
Yes, it was a nice and sunny day yesterday and my work area - I `m also painting -was full of light.
May be, it`s not too far away when I post a few pictures of Münsingen? A picture tells more than 1000 words...

Hi Thomas

Nice project too! I like it.......

Hi Gerhard,

Railing and deck support nearly finished. After some furter refinements I will paint this brass parts white.
Boiler parts are under way!

Hi Thomas

She`s goin`to be a really tall, strong and elegant lady!

 The Regner double cylinder will work well with the wheels as I think. I am awaiting the pics from your boiler, will you build your own or use a common market product? 

Regards
Gerhard

[Hankwilliams]

Hi Gerhard,

thanks for your interest. For longer time I considered, to use two boilers, each for one funnel - but now I think, one boiler will be safer. Without that, in front of the engine will be not enought space, the boiler must installed behind the engine.Next week I`ll get a brass boiler tube of 100 mm diameter with a lenght of 200 mm with two lids(?). A usual in trade coppertube of 28 mm diameter with some crosstubes will be the fametube inside the boiler like an U.
For most of my models I`ve built the boilers by myself - it`s not a too difficult job and it`s much cheaper than a market product.

Hi Thomas

That`s true! Prices for traded boilers (and engines!) are pretty high, and with own constructed parts you are free to make them in the exact size you need them. I have never soldered boilers until now, will have to do this when my Rigi build continues. For my Cairo project I will need a boiler too, so there will be chances enough for me to proof my skills............
