Hello all,
I'm new to the forum and I'm hoping this will be the best place to locate a PRV.
To the best of my knowledge I have an old Renown steam engine that I've recently inherited. I've managed to seal up the leaks and make it operate very well. This toy sat in my grandfather's basement for decades and I'm not sure where it came from. The PRV is completely corroded even tonthe point that the threads are damaged. I've thought about making the part, but I don't know the specs and would rather not dance with the devil.
Any help would be appreciated.
Welcome to the forum, I can see why you’re guessing an Australian Renown, but you actually have a Candian Wilson model S2 from Toronto (to add to the confusion, there is also an English made Wilson)
It will be very difficult to find a spare, and you will likely have to make one or have one made…

Is this a steel boiler ?
Thanks for the reply, now I know. You don't know by chance what year(s) they were produced. It also looks like I have to dust off my lathe.
It appears to have a cast aluminum base, formed aluminum pressure vessel and brass flywheel.
That dating makes sense, my dad always told me it was his. He was born in 43. I can see how these can become a real hobby. As an industrial mechanic and boiler operator, they're absolutely fascinating. Once I greased up the shaft and the steam driven parts it operated very well. I'm not sure what the recommended lubricants are for these things, but I has some Lucas engine assembly lube which is like honey and has a very high zinc content for metal to metal contact. Thanks for the replies.
I found the article in my Toy Steam News, unfortunately I cannot post it on here as it’s all copyright material… Dick Cutler (author of the article) states that they were likely built sometime after WWII when there was a surplus of aluminum available. He also says it has a double-walled water jacket boiler with a central flue tube.
There is also an exploded view/diagram of the engine and it lists the safety valve thread as 1/4-28 thread.

Nick,
You can post a snippet or two:

Doing so here is clearly research and teaching.

I really don’t know how it all works and being friends with some of the writers/owners of Toy Steam News, I don’t want to upset them… A “snippet” of the article would pretty much be the whole thing as it’s only a page and the exploded view has the authors name followed by (All Rights Reserved)
