Smile Steam Engine Ready to Fire

It has taken two months to free up this single cylinder engine, build a boiler and couple them together. Air tested to 100# and hydrostatic test to 200#. I'll move it out of the shop and have a first fire party this Saturday!

Interesting.

I have a few questions.
How is your boiler designed?
Plate grade & thickness, water tube or fire tube?
How to you add water?
Where is the pressure relief valve?

I do not see any stays on the flat surfaces.

Appears to be some sort of water tube boiler?

I see the relief valve now. It is mounted on the steam line between the pressure gauge and the engine.

Here is a bit more info:

The engine was made before 1872 by the Sinker Davis Company in Indianapolis and we found it sitting in a back yard in Hayden, Idaho. Took a couple of days to get it freed up and running on compressed air. My son, Jim, supplied 3 pieces of 6” high pressure gas pipe for the mud pipes and steam pipe to construct the water tube boiler. The big pipes are connected by 10 short pieces of 1” schedule 80 pipe exposed to the fire to convert the water to live steam. I plan to run the boiler at about 75 psi

The certified blow-off valve does work as advertised at 150 psi and the sight glass accurately shows the water level in the boiler. I’ve got the governor backed all the way out so the engine runs at a nice slow 200 rpm. The feedwater pump is made from a hydraulic cylinder with check valves coupled to the upper part of the rod ( I think that was where the original was mounted ) and adjusting the stops on the slide rod control the amount of water injected on each stroke. I'll link to a video - much easier than trying to explain.

Looking good...You might want to rethink the water glass placement. When things get hopping, it may or may not come under more stress than you think....that would also allow you to swing your pipe joints, something I try to do at least once in each pipe run between a boiler and any major appliance...
Just my 2 cents...

Thanks. The lower pipe to the sight glass can pivot as needed and I threaded the bottom end of the guard rods and put on a captured nut just to make sure the compression joints on each end of the sight glass couldn't slip off.

Looking at the pictures a couple of times brings one question to mind. I didn't see any sort of lubricator, hydrostatic or mechanical, to feed into the steam line. Did I miss it?.....PD

The steam flowing past the site glass will probably distort the level when the engine is running, so the water level will read higher than it really is.

I think someone else already brought up the concern of the steam line vibrating from the engine movement, possibly causing the water glass to break.
