Hi Bernard,

Try with Elde Modellbau in Germany, he usually keep R  & L hand in stock:
www.elde-modellbau.com

Or Eskader in Sweden:
http://eskader.hemsida.eu/index.php/fartyg/ovriga-detaljer/propellrar-tillbehor/massingspropellrar/propeller-av-massing-4-bladig.html

Gess you master Swedish being a Dane !

Cheers, Bjorn

Good evening!
My choice goes (now) to Raboesh that I get from there:
"http://shop.modellbau-kaufhaus.de/modules.php"
I find them a good copromise between quality, price et availability in different type and size. Right or left hand side = no problem.
On top of it , the owner of this site is very nice and  will answer to  you even on Sunday night at 10PM.
They speak any language (through translators) and will do everything to help you out.
Sincerely.

Ooopps! 
BBJS passed in front of me.
I did not know that Elde was proposing propellers. But what I know , is that he is doing very good work.
I keep Eskader in mind. I did not know this manufacturer. Good to learn.
Thanks and regards

I tried a four blade Raebosch which I purchased from the Australian shop, Float A Boat behind the PM Research V twin last Sunday. The 70mm size worked very well and the make them in left and right, also either 4mm or 5mm shaft for sizes above 65mm. Also looks like a scale prop so I was very pleased with it. Cheers, Ian.

I think Bernhard is looking for steam scale props -> high pitch for low rev, such as those made by the Prop Shop (but which are only left-hand). I think the Elde and other propellers are meant for electric motors -> high rev -> low pitch.
I'd like to know if there is another source of propellers made specifically for steam engine use.

tHANKS to all ......Bot like Kno3 sai.......a special prop to steam...will be the best..........

Regards Bernhard

have you try  this from.. Rivabo...  65mm M4 Threaded 4 Blade R/H Brass Propeller
Rivabo Brass 4 Bladed Propeller RH (A-Type Blades)

Raebosch make identical looking props which they also call "A Type" in both left and right rotation. The biggest they make is 130mm dia with a 132mm pitch. All sizes above 65mm dia have a 5mm shaft. The larger sizes are only meant to rev to 2700 maximum. I have several of these in different sizes behind steam engines and all work very well. Hope this helps, Ian.

Hello!
I'd like to have your advice concerning three blades propellers (rivabo) with steam.
I am more & more convinced that the 4 blades (Raboech) gives : better move, less RPM , thus more autonomy!
Also I feel like i need to use the prpelle as big as it can enter behind the rudder.
What do you think?
Cordialy!

Without having much experience with props, I also think that all else being equal, for a steam engine it is good to have a large propeller with many blades and/or high pitch. This is because a steam engine has a lot of torque at very low rpm. So by using the larger prop (or with more pitch) you take better advantage of the power and conserve steam.
This of course apply to "normal" steam engines, not the high speed single acting ones (e.g. Stuart Sirius, which turn much faster).
