A lovely project, well completed, and I'm sure it will be very useful.

Thanks mates! :beer:
Andrew, I thought about a weight but worked out earlier that it would take 4 ounces on a 1/8"" bore for 20 psi, which is rather a big lump, even if lead!
The earlier lever style had a mechanical advantage so the weight could be more reasonable in size.

How can you make a new boiler without wanting to make a new engine?

I have no idea where I'd find bronze balls or wire, or how I would drill and tap the ball, and I don't like the idea of the spring being in the boiler as much as outside. Nevertheless I'm sure these give satisfaction -- just not what I'm favoring right now.

I know this is an old post, but since I missed it the first time around, I thought I should take the opportunity to chime in now.
First, brilliant build. Thanks for sharing.
Nowadays it seems that just about every podunk town has a piercing/tattoo parlor on every corner. Those places will sell piercing jewelry consisting of a couple of steel or titanium balls, threaded to accept a post. Sizes range from 3mm to 8mm diameter ball and with a post length of up to ~24mm. This jewelry is available for somewhere in the €5.00 range.
You can use the threaded balls and posts in valves, governors, or put 'em in your :bugeye:
Just a thought.

So there's a challenge for you miniature engine builders - make an engine entirely from metalwork intended as 'body ornamentation' (shudder - I hate the stuff )
