Because Walthers 45' log flats are near impossible to get now and because I don't want to fork over $20 per car for a Custom Finishing car (Which are very nice,) I've decided to build kitbash my own, much like many late loging roads did. I bought some Details West PC&F log bunks the other day at my LHS that are especially built for converting normal flats into logging flats. Question: Directions say to remove a scale 33'3" of the decking from a 40' or 50' flat. How do I do this with out ruining the rest of the model. Since Athearn Blue Box kits are hard to find right now (Never thought I'd say that) I was thinking about using Red Caboose 42' flats. Do these have seperate decks or are they molded one with the body? Thanks.
