Re: digital steam engine indicator
Webb's compounds were known for not starting because of the axles not being coupled. Wise station masters would arrange for a shunter to be strategically place to offer a helping hand, such was the power and influence of Chief Mechanical Engineers in British railway companies. Now't to do with engin...

Re: A Windemere Kettle
The image looks quite coppery, must be the light from the door behind. I know what you mean about copper pipe. Its just copper is more reactive at high temp, the hot water in this house is distinctly off in taste, even when cool, and it is not uncommon for Cu hot water tanks to waste from the inside...

Re: A Windemere Kettle
Lovely sight, Have you thought of tinning the interior, not with plumber's solder but with modern pewter or pure tin, saves ingesting too much copper.

Re: Feed into twin drum watertube boiler
As Mike is local I thought he might like to know the Daniel Adamson (3 furnace, coal, riveted Scotch weight about 20 tons) has been fitted with an electrically powered hydrokineter to overcome the problem of a "cold bottom" mentioned by Fred earlier. The original feed pipes were taken up to the wate...

Re: Feed into twin drum watertube boiler
Hi Mike Its a good idea to give feedwater plenty of space to get rid of dissolved oxygen before it impinges on a tube or other part you don't want oxidised away. I've noticed on 3 and 4 inch traction engines that tubes opposite feeds can rust out quickly and know of one instance it was in four years...

Re: Injector Designs?
Pity you had to go because DAG Brown brought along the brazing up jigs he uses for the bodies as well as his cone reamers. His book "Miniature Injectors Inside and Out" (Camden OS, Tee In Stock on website) contains enough to do some sums to calculate nozzle areas for larger examples plus photos of t...

Re: K. N. Harris' Twin Launch Engine
Hold the book open at 90 degrees, light it evenly and use a camera. If you organise it properly you can keep the page flat using strips of lead covered in cloth placed along the top and bottom edges. If the lead is in the form of an L it will not slip away. You don't want to break a spine. Interesti...

Re: Steam water heater
Daniel, there is nothing to stop a lifter being used to take water from an internal tank, you might want to put a very light non return valve on the supply side. It has the immediacy of a pre heated Wm kettle without the danger to the skin. Windermere water isn't so great when the blue algae bloom, ...
