Hi Bernhard,
well, I didn't construct the whole locomotive before I started.
I made some drawings (simple CAD) of the wheelsets, trucks and frame. That takes me a couple of weeks and I used the drawings to create the list of material to place the order at the metal shop.
The only parts with some more detailed drawings are the steam engine and the steam boiler. But this were made during construction of the frame and I did'nt note the time that I spend on this. In the end, I made several designs of the steam engine and reworked it on a daily basis. Actually, there are some more improvments in the final steam engine, that are not shown on the drawing.
Most other construction is done in my mind only with some sketches on paper to note dimensions. It's easy for to take a block of raw material and to lay out all processing steps in mind to get the final part.
The only time count that I have is the total building time that I've spend - Actually 435 hours, in over 40 month. And I guess that there will come 200+ more hours, until the Shay is finished.
Cheers, Gerd
