Twin cylinder mill engine, slightly rusty.....

Hello all

I just got this home and was wondering about:

- The make, model and age
- Features which may help ID it, the rounded box bed, the bearing mounts are 'different', has some square headed bolts
- May have had a governor, as there is grooved pulley with inline with a vacant hole which looks like it held something

This moment of madness is going to be a long term project and I was wondering about the best approach.

- The wooden base is rotten so that's for the bin
- It's seized solid, so was thinking of giving it a bath Evapo-Rust (complete immersion?), did consider Electrolysis, heard that's very bad for brass
- Once majority of rust is off then penetrating fluid on all bolts and moving parts

It looks a lot worse than it actually is and I'd like to think, with a lot of TLC, it could be returned to its former glory. Has anyone out there completed a similar project with an engine in a similar state? Any advice (apart from take it to the scrapyard) gratefully received.

Here are lots of pictures

here's a couple more ......

I've a couple of photos of that engine look like they were taken in 2012. I don't think we could put a make or maker on it then.

Also a similar style of engine.

You could certainly buy things like cylinder sets, crosshead guides and assorted other parts at the time and arrange them as you wanted, the likes of Stevens's Model Boat Yard did then around 1920

A very beautiful steam engine and its design is well over 100 years old.
I have also once taken apart a heavily rusted engine. I would spray all parts and connections several times with WD 40 and let it work for a while. You can then process the parts mechanically with brushes, but this won't completely remove the rust. If you don't want to paint the old engine, that's ok and everything will be well oiled. The piston rod would have to be replaced but you'll see that later.
If you want to treat the engine with paint you definitely have to do more. I used a paint in my restoration (Hammerite). This paint also holds up on rust.
It's all a matter of personal taste.

I bought this from an elderly gentleman and it belonged to his even older friend who was worried when he wasn’t around it would end up being thrown out. He said it was found in a collapsed work shed in Redhill some time around 2000. Not only do I now feel obliged to, but really need/want to restore it to its former glory.

That's definitely the engine in the 1st picture, what a coincidence!

I wonder about the flat belt pulley on the opposite side to the grooved pulley is that a usual configuration?

So sounds like penetrating fluid first and removal of rust second, I'm in no rush, if its been knocking around for all these years a few more won't hurt
