Re: K. N. Harris' Twin Launch Engine
The book says that details can be found in The Engineer for 20-6-13 so it will be in imperial measurements then!!! Is anyone subscribed to them and can check back copies?

It looks like it uses 2 Stuart 5a cylinders at £65 each

Re: K. N. Harris' Twin Launch Engine
I took that to mean that the design of Dendy-Marchall's locomotive was in that issue of "The Engineer", not Harris' twin, so hadn't followed it up. For those wondering it is not 2013, but 1913.

Re: K. N. Harris' Twin Launch Engine
Re reading the text I think you are right. The 1913 date is far to early to be relevant to the launch engine which is designed around Stuart parts which may not have been on sale back then, but I'm no expert on Stuart's time line on different engine designs.

Re: K. N. Harris' Twin Launch Engine
I've just noticed that figure 60 in the book is dated up at the top centre 6-7-62 (or 8) proving your line of thinking. I suppose that Mr Harris is assuming that the info contained in the book is sufficient for the engine to be built, which it probably is if you often design engines. If there had been detailed dimensioned drawings, he would have mentioned the fact as he did for the engine in chapter 11.

Re: K. N. Harris' Twin Launch Engine
I've tried scanning the drawing, hoping to increase the size and make it more readable but with little success. It is too close to the end of the book to get a clean scan (without cutting out the page. If I spot another cheap copy I might just do that).
Late Edit : - Perhaps a search of the Model Engineer around 1962/3 might throw something up?

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.
Interestingly this was the also way a certain large museum did it when I wanted some boat plans copied from a journal. Some of their lead weights were covered in chamois and the frame for holding the open book very smart. Mine is a piece of 3 mm steel bent at 90.
