The S50 was an eBay purchase, which "ran on air". After receiving it, it indeed ran on air at around 40 psi. The timing was off, and made nearly permanently so by placement of a set screw. Some fiddling with stroke length of valve and port facing and I was able to get it to run on minimal pressure, and now it is self-starting with no real issues. The boiler was bought separately (ebay) and required a respray. Pipe work is PM, as is the valve, whistle and lubricator. PM is threaded at 40 UST and required tapping bushes to suit.
The pump is a PM unit, and is attached to a water tank of my own build. Made of remnants of a customer's copper mailbox, donated when an errant delivery person ran it down after leaving a package. I salvaged quite a bit of sheet copper and though some of it is creased it has value.
The sad looking chuff pot is also of my own design, and I give great respect to you craftsman who make this particular job look easy.

Good job saving a cobbled up engine. The entire plant looks good now and that condenser is way better than anything I've ever been able to make. Good work. That boiler looks great!

Neat plumbing and everything looks and runs well now 

If anyone missed the extra pictures in the link above, they are definitely worth checking out 

Any particular use for the gear on the S-50?

Is the base recycled or your creation/design? I like it

Thanks Nick.

The gear is intended to link to a transmission for driving a generator or such, but I have yet to finish it. On a side note, the carrier for that sprocket will actually hold a pulley as well, so I can with the removal of 4 screws swap from gear drive to pulley.

Thanks- out of curiosity does the bronze cylinder give any indication of age?

I think Stuart stopped producing bronze cylinders for the S50 in the 1980's but i might be wrong about that. I know the factory machine kits i've seen had bronze cylinders and the bases were painted all black, i know Nick owned one.

That I did, sold it on eBay last year and now have to early round-crank S-50's
