Hi! I'm returning to active modeling after a hiatus far longer than I'd care to admit. I'm trying to build an MDC HOn3 kit of the D&RGW C21 (outside frame). I'm having trouble with the side rods binding and can't figure out what to do about it. One of the side rods gets real tight when the cranks are in the horizontal position, which suggests that the spacing between the crank pins and the holes in the side rod are not the same. I've swapped the side rods and the problem remains on the left side of the loco, so it would appear to be a problem with one or more of the cranks. Beyond that I'm stumped. I followed the instructions about keeping the punched side of the side rods in on one side and out on the other, but have also tried other combinations to no avail. Does anyone have any ideas on how to fix this? Thanks in advance!
