Lady Stephanie Pumping Engine
springcrocus:
A couple of years ago I lost my enthusiam for recording my projects, mainly because of the arguments and negativity that abounded on the loco site that I used to frequent. What I didn't lose was my enthusiasm for being in the workshop and a few projects have now been and gone.
Following my request for help identifying a suitable flywheel Jo kindly offered me a surplus one from her collection of castings and to acknowledge Jo's magnanimity I decided I would record my building of the Lady Stephanie pumping engine. I am using drawings from Julius De Waal and this particular model is about 30% larger than the ones that others on here have made, the base measuring 320mm x 100mm. However, rather than blindly following the drawings, I am modifying components and sizes to suit my methods of manufacture whilst retaining the general outward looks and basic dimensions of the model.
The whole of the framework will be painted and most moving parts left as polished steel or brass. The two lower front panels will have perspex windows to allow viewing of the pipework and pump, along with the governor linkages. I'm hoping to make this an actual working model so the pipework will be connected to a water source to allow proper pumping to occur.
I've kicked things off by making the baseplate and platform from 100mm x 5mm hot-rolled mild steel after removing the mill-scale by pickling in citric acid, all holes being placed using the DRO on the mill. The uprights have been made from M8 mild steel studding.
The square pillars that separate the base and the platform have been made from aluminium box-section with separate aluminium end-caps for either end. Rather than have my chuck jaws mark the work, I faced the sawn sections to length with a flycutter in the mill, holding the work between two vee-blocks to ensure squareness.
The end-caps were made from 22mm square aluminium, milled to fit inside the box-sections and drilled 8.1mm to fit the studding. The outer faces of the pillars were fluted with a 4mm dia ball-nosed slot drill, just to add a bit of decoration. The slots in the end-caps provide support for the face and end panels panels.
More to follow.
Regards, Steve
