While I was recently conflicted between HO gauge projects in 1:32n20" and 1:24n16", I decided to build some long dormant Gn15" Heywood 3' x 6' cars that I thought would look reasonable in either scale. Starting on the kits renewed my interest in 1:12 scale modeling, with the kits representing half-scale models of Heywood cars in 1:12 scale.
These were multimedia kits offered by Jeff Saxton many years ago, designed to use NWSL On30" wheelsets. I modified the kits by cutting notches in the end beams to accept Kadee S-scale knuckle couplers, with the magnetic activating parts snipped off to allow mounting them at conventional HO scale coupler height. These were fit in and then secured in place with E300 adhesive applied with a scribing tool (cheap plastic dart from K-Mart with the plastic fin assembly unscrewed and discarded). To test size, I decided to build one each in 1:32n20", 1:24n16", 1:18n1, and 1:12n7.5".https://www.flickr.com/photos/serpent_vision/22432194655/in/dateposted-public/
Liking the effect in 1:12 scale, I made a couple of cradles to allow them to carry a pair of toy barrels that I had acquired over the years. The barrels are accessories for Lord of the Rings Bilbo Baggins action figures, when he celebrates his 111st birthday. These are pretty consistently available in the $10-15 range (US shipping) on eBay (search "111 bilbo"), and more rarely can be found for a bit less. They are a bit toylike in the level of detail, but might be improved with a better paint job.https://www.flickr.com/photos/serpent_vision/21811087173/in/dateposted-public/
The cradle pieces are cut from 1/8" thick basswood, with NBW pieces from Grandt Line added. 1/8" thick strips were cut from K&S sheet brass, bent, and glued onto the sides to straddle the deck of the car. Grandt Line 0.063" round rivets were glued onto the brass strips. The cradles were painted Polly Scale Tuscan red-brown to match the 3x6 cars, and the hardware was painted Testors acrylic flat black.https://www.flickr.com/photos/serpent_vision/22432194195/in/dateposted-public/https://www.flickr.com/photos/serpent_vision/22406211756/in/dateposted-public/https://www.flickr.com/photos/serpent_vision/21809477954/in/dateposted-public/https://www.flickr.com/photos/serpent_vision/22244254360/in/dateposted-public/
