An unknown Twin Marine Oscillator

(1/4) > >>

Sanjay F:
I've got a little side project going on with with this little Twin Marine Oscillator of unknown origin; so I guess the first question is does anyone recognise it? I can't work out if it's kit built from castings, commercially bought from a manufacturer or handbuilt. The drip trays underneath are made of pressed brass which I don't think most home hobbyists would/could do? Maybe its been made from parts from the Stevens Model Dockyard catalogue (see picture)

The next question is if its single or double acting, I've stripped it down and you can see the ports? This ones a runner after some oiling, makes a change and works in both directions dependent on which pipe you use as an inlet. It has a lot of rust, grime and some modern screws so I'm going to strip off the rust clean the brass, leave the paint original, remove the flywheel wobble if possible and replace the very fine oil pipes leading from the unusual little oil resevoir.

Any information most gratefully received........

Sanjay F:
Strip down pictures....

Jasonb:
Double acting. The steam can go in one end of the cylinder while the other end exhausts ( no open cylinder end) and then as the cylinder angles the other way will exhaust via the hole it just went in while what was the exhaust lets a new load of steam in.

If not from Stevens then there were other makers of similar cylinder sets.

Sanjay F:
Now that's interesting that pivot, steam block and cylinder from that catalogue look very similar.

Other than Steven's what are the names of other manufacturers of parts from that era? It would be good to have access to their old catalogues as reference material

Jasonb:
The Macmillan one can be bought as a download from Camden Miniatures, get it before they shut up shop.

To some degree, most of the other names did parts, some more than others so that would be the likes of Gamages, Bassett-Lowke, Whitneys, Avery, Simmonds, etc
