I thought I would start a thread to throw up some pictures on of the Stuart triple expansion engine i've been working on for, well, forever.
Here's the completed Hilmar thread. I call it a Hilmar thread because had Hilmar not gone out and single point cut the 3/16 20 double start internal thread I wouldn't have believed it possible. I actually almost got it cut in the lathe and then through a moment of mental fraility broke the itty bitty tool (not by cutting, just a very dumb movement). This stuff is small boring bar only .100 in dia! I made a tap to chase it to finish it off.
I'm further along than the following pic shows but had the engine apart to clean and fit some recently manufactured parts. Anyway, at this point of assembly, I took some pics using a technique called light painting. Basically you leave the shutter open in dark room and use a moving light source to create the exposure. This lets you emphasize and control. For a model I was trying to create some contract, more of a dramatic looking pic and also deemphasize or fade out the background. High f stop for lots of depth. This a new technique for me but its interesting, gotta learn more
