EDIT: almost forgot, n scale! man, don't you just love those drm logging cars. but woa! the price. decide to see what i could do with styrene. .020 v groove for deck, .080x.100 for side frame and .40 strips for ends. a couple sizes of tubing for bolsters. ah, the bolsters, the tricky part. glued a tube ina tube (sorry don't remember the dia.) glued this to car bottom, filed to correct height checking with mt truck. drilled to .076". mt bolster pin fits real nice. details on order. will have to use load for weight. used an atlas 50' flat for reference. half the length and a wee bit narrower. i can knock out the basic car in 15 minutes. other cars on this built on this basic flat are planned. 75% of the cost is the mt trucks. david i gotta buy a camera. never thought this would be so easy.
