Drag
by John
Not what you thought.
Today I made the rest of the drag links for the triple expansion steam engine, and just for fun I made one spare.
I ran out of BA10 nuts. Ordered more. 1.6mm thread, 3mm overall diameter, 200 of them weighs nothing. But if I drop one, that is another 25 cents down the drain, because individually they are invisible.
