I have managed to acquire two props (thanks Dave M), but I require two more for the other two torpedos.
The suggested use of a 3D printer is also a non starter and trawling the internet has also drawn a blank.
Any ideas where else I might try?

Thank you
Steve

Hi, Are these for working torpedo S or static? I would guess static. Presumably the two you already have are OK. Could you make a mould and cast new ones up?

Hi Edward. Yes, they are static and the two I already have are ok.
I have never done any moulding or casting before. Maybe I can give it a try. Any pointers?

I have never cast resin but am currently casting lead. You need to ensure that you can extract the final product and that you can get the air out of the mould while you are casting. I suggest you look at something like Google or uTube. Alternatively someone on this site may be able to advice you. Whatever you do, please let me know how you get on!

Hi Steve
It would be possible to make a silicon mould and cast with Fast Cast resin. Quite a lot of work for just two parts, and making the mould to allow the air to escape would not be easy.
You could make the parts from some plastic rod fettled to shape with the blades from Litho plate cut to size and super-glued in place.
Having originals to copy should enable fair replicas to be fashioned and as they are static and part hidden in a tube round the props I believe it is do-able.
Good luck
Dave

Morning Folks. Thank you for all the advice.
The prop, as you can see, has eight blades which are at different levels on the spinner. Having no experience of moulding, my latest plan is two use the two props on the rear torpedos.
Unless I can find suitable props for the front torpedos I leave them out altogether. I can also leave the two forward torpedo launchers empty.
As Octman has suggested, I can always say that the props are not visible as they are spinnng up for launching.
Bit of a cop out I know.

Steve
