DOOR STOP STUART BEAM ENGINE ON STEAM (2nd STEAM VIDEO ON PAGE 2)
Posted by therat05 on 22 Apr, 2019 05:04 -
Is it only me that does stupid things? like buying a Stuart Beam engine without testing and hardly looking at it, there was a reason as i had just purchased the buy of the century a stuart 504 boiler and S50 steam plant for very little money...this deflected me somewhat and the door stop was purchased also cheaply.
The beam engine on examination later was covered in crud and fitted with many non standard parts,an example was small copper tube used as watts motion spacers, the watts motion itself was all different sizes..the valve links both different and crudely made...all nuts and bolts different sizes and types ie allen bolts on the piston cylinder in fact the whole thing was a mess and obviously did not run.....I had bought a door stop.
First i tried to get craftsmen to rebuild it for me without success they wisely declined...So back to me then if i wanted the beam engine running i would have to do this myself.... it was stripped down and all non standard parts dumped and new parts purchased ..made by Kevin and myself ..or scrounged until i had all the parts required.... eventually it was time to put all this stuff together.
The engine parts were prepared degreased and undercoated and primed then sprayed in my team colours of Industrial grey Halfords enamel, 2 coats undercoat and 3 top coats, some details were lined freehand with Humbrol enamel Red... the pile of bits before me was then put back together using all new nuts and bolts of the correct sizes...the piston rings which were broken and metal as standard on this machine were removed and a viton 75 O ring fitted 19.5mm ID x 2mm C/S I knew this would run as my Stuart No8 has a similar piston and that has an o ring piston ring as standard, i made a complete set of gaskets the machine was now assembled.
The test was on air to start with ..the valve was a bit troublesome to set, the problem being the gasket was to thick on the valve body keeping the valve away from the face so permanently letting by, this was resolved using a thinner gasket...the engine then burst into life ..what joy seeing something i thought would never run... running...the only problem was the crank klunks which is something that i can get replaced at any time, i do not mind the klunk as it sounds like an old ships engine...it sounds much worse in the video than in real life ...the engine ticks over on 10 psi the real test will be on steam.
Here are some before and after pictures and a couple of videos..the first video is of its first ever run on steam no practices followed by its first test run on air....Steve

Hello Bob
i thought it brushed up quite well

I like the grey paint. It looks "industrial."
I have an unpainted Stuart beam of my own. Maybe it should be grey....

Grey is a good colour as it goes with anything..these beams also look good in Green...Steve

Green is my other colour choice.

This Stuart Beam is painted “hammerite Hammertone Green “

That looks excellent i like the rings on the column picked out in Gold ...i have another beam that is in Stuart green with the column made in Stainless steel....Steve -

Those rings on the column are polished brass
I turned the cast rings off and turned grooves then placed brass rings there
Only one of the few things I did to make it a different stuart beam

Never thought about hammertone paint....

That is very good Dennis and a novel idea...Steve

You guys are making me want to dig out my "boat anchor" Stuart beam and strip it down and make it over, or at least get it running. But to do that I'd have to bump a dozen or more priority projects out of the way first.
Maybe next winter?!?! -

Maybe next winter?!?! Boat anchor ...Door stop..we could start a trend here Stoker...12 projects is a lot of work but you should run with the current theme and get right on the anchor job

Mine arrived as a set of castings started by an idiot .
Suffice to say holes in wrong places and all sorts of issues.
Those who study it will see I have no outboard bearing for crank.
I fabricated a crankshaft and have both bearings on board .
Makes for a stable engine and smaller footprint .
Cheers

I wish i could do that sort of stuff Dennis ...my engine was very poorly made but had been running in the past having

a long hard life and was badly worn, so my skill if you can call it that was to make drawings and careful measurements so some one could make me up what i needed which they did, my contribution was to get the thing rebuilt and set up properly then carry out work to the piston and valve to make the engine run and finally decorate it....Steve -
