As I was starting to turn up the crank pins, I figured I’d better find out if they would fit through the holes in the rods. They don’t, but rather than keep dragging out the whole etched sheet, I parted them off. Then, thought I, well I may as well fold them over and solder them up so they’re a little more robust. So here they are: ahead of schedule.
I left the folding tab on the crosshead end of the main rods until I re-drill the holes as these filled up with solder.
I had conjectures that the two layers of half etch, plus an extra full-thickness area on the back bottoms would make these rods slightly more robust than those on #10. Low and behold, they definitely feel stiffer.
