I have recently purchased an SVS steam plant which is in need of refurbishment. Can anyone recommend what type of paint to use. I would also like to repace all the fittings and would appreciate any comments as to thread sizes and where to purchase. I understand that SVS are no longer in existance. Can anyone help please?
many thanks david

Do you have a little more detail? Or a photo if possible.
SVS made a couple of plants: The early models were a tiny (I have one) twin oscillator with 8mm bore and 12mm stroke. This plant was originally available with a simple pot horizontal boiler or a centre flue horizontal. Later it was named the Heron with a horizontal centre flue boiler or the Vale with a vertical boiler. At the same time the Vale and Heron were available the Snipe also came along with a more sophisticated boiler design and enlarged to 12mm bore and stroke. The Snipe was a direct competitor to the Cheddar Pintail, although as I have never seen a Snipe running, I cannot say how they compared performance wise.
In the information I have, there is mention of safety valves with both 1/4 x 40 and 3/8 x 32 threads, so I would hazard a guess that the bushes will be pretty standard, but I will go and check the boiler on my early SVS twin.
As you say, SVS are no longer in business, as when Mike Legg retired the rights passed to Tony Green, who sadly passed away a little while ago. As far as I know, nobody had picked up the rights to these plants, which is a shame as they are nice little engines.

Sorry should have said its a "SNIPE" plant

Ah right.... Can't help you then :embarrassed:
I had a look at my boiler and the fittings are all smaller than 1/4 x 40. I don't know what they are , as none of my (not very large) collection of ME taps fitted.
That's a nice plant you have there and quite collectable (not that I'm into collecting). Should push a reasonable model along.
Fingers crossed someone with a bit more knowledge than me can advise regarding fitting sizes. As for where to buy, Polly (Bruce) Engineering, steamfittings.co.uk, Macsteam, Maccmodels, Forest Classics, Cotswold Heritage, all have a fine selection of fittings.

Thanks for trying

The Tony Green website still comes up http://www.tgsm.co.uk/acatalog/Marine_Engines.html Are you saying Neil that the business no longer exists? A pity if so as I was going to order some SVS and some Unit stuff from there. Regards, Ian

Ian, you could try dropping them an e-mail, but there are threads elsewhere in the forum that confirm Tony passed away a little while ago.
The trouble with web sites is that unless the subscription runs out, or someone tells the provider to take it down, a web site will still appears to be live.

I think you will find that Tony Green business is still operating they quite often attend Mobile Marine open days not sure if it's Tony's son or son in law who now operates the business

Great, thanks for that, I am always a bit wary of ordering from sites with shopping karts but it is good to know they are still trading. Cheers, Ian.

Tony Green Steam Models are producing both the 8mm bore and the 10mm bore engines I got myself one a couple of weeks ago, excellent service the engine arrived in 2 days along with its lubricator. It is a well made little machine, and I soon had it running on steam from my Krick Anna boiler.Any spares can probably be obtained from TGSM. they are also excellent value for money, at £155 for the engine and £19.99 for the displacment lubricator, plus, of course the obligatory p+p. :-))

That's very good news. I e-mailed them, asking for pictures and got no reply.
You have now helped me to identify a 'mystery' twin cylinder oscillator I won on ebay some while back, it is pretty much identical to yours.
Please let us know how you get on with the engine.

so far so good, I have been running the engine in on steam from my little pot boiler as I do not have a source of compressed air. after a little initial stiffness it is now nice and free, as soon as my Maccsteam boiler arrives, I can run some proper tests as the Krick pot boiler isn,t really man enough for the job. I am thinking of putting it all into a Krick Borkum, as I believe these little engines will quite happily swing a 2 inch prop and drive a hull up to 42 inches long.
