Nice build!
To make your last pipe connection, just use a pipe union in a convenient place.

But it would still be the same principal as when you turn the pipe
Union one side will loosen?

Not at all. Next time you’re at Home Depot or someplace like that, find a pipe union and check it out. You’ll immediately see how it works.

Was this the 35 Bruce restored? 😳

Yes, the cylinder cracked, and I don’t have the ability to silver solder it.  It’s all good.  Makes a great boiler.

Completed this today.   Spent most of the week prepping the wood plinth with staining and sealing and drying.   This build was very tricky and was like a jigsaw puzzle.

Utilizing a Jensen 35 electrically heated boiler. I removed the engine off the top of the Boiler and soft soldered the steam chest.  From there I fitted 1/40-40 UST pm research pipe work to the boiler through a globe valve. From there, travels down to a Microcosm whistle with a Tee fitting.  After that, it goes into the bottom of the Governor and comes out the front with a Reducing bushing to 3/16-40 UST.  The engine was drilled to this size. After that due to the Governor pulley location I had to do some intricate pipe work to route it to the steam inlet of the PMR#3.  Getting the strap for the Governor to the correct tension is very tedious and I’m still tweaking it.

Exhaust is very simple at this present moment, comes out as 3/16-40 to a small cup.

Runs very well, and has a transmission for accessories. 

I really like brass pipe work against dark wood grain. Let me know your thoughts on this one![attachimg=1][attachimg=2][attachimg=3]
