They were just eyeballed and bodged from a picture of a completed Iron Mtn kit and a picture of something similar in Dakota (or was that the Iron Mtn line?) I did have some plans from Garden Railways to give an idea of size, but didn't follow all the details - in particular mine don't have operating doors.Shawn said:like the way these ore cars came out. What did you use to make these? (looks like a HLW flat) did you use plans or just eyeball it? Im thinking about making a set.
The starting point was some (incorrect) axleguards that came off a bad buy on eBay - they were the only usable bits on two small vans which turned out totally toylike; luckily I got them very cheaply. Having cut them off the donor vehicles I fixed them to some pine stripwood chassis members with glue and pins, then glued these to a floor of 80thou styrene with the plank ends scored in and slightly distressed. More stripwood was used for the chassis ends. The body panels were from more 80thou styrene. The upper framework was some slightly smaller strips of pine. Brake and door release wheels by Ozark, grab handles from soft garden wire.

I also built the three larger ones to fit some Playmobil wagon underframes that I cut down in length.

This picture shows the original chassis behind one that has been modified. I added lengths of plastrukt I-beam girder to strengthen the join in the underframe and make it look like a wagon built to carry a heavy load.

This one shows one of the larger cars, unpainted. The smaller top frame was balsa, painted with several coats of button polish to harden the wood.
