Got another build update.
I have painted the boxcar and trucks, and installed Kadee style 743 couplers. The couplers are gauged using a Kadee height gauge.
The car couples and uncouples smoothly, and rolls quite freely. Final weight is 13.70 ounces.
Some more quick lessons learned:
I forgot the turnbuckles before painting.
The Bolsters are a little off. They should have been a little more toward the end. The trucks are sitting a bit to far in for my taste.
The paint is Scalecoat 1, Boxcar red #3 from a spray can.
All that's left is to apply the decals, and then hit it with Dullcote. I should have final pictures later this week.
