Walthers also had a beer can tank car kit (and no I do not refer to their tongue in cheek model with an actual beer can) - it is listed as a 30’ funnel flow and the actual tank itself is 24 scale feet long.
I suggest you find the February 1977 issue of MR which has an article by Jerry Pitts about kitbashing a beer can tank car using full length tank cars cut down. Pitts says the beer can tank cars varied between 23 to 29 feet. He used the AHM 50 foot heated tank car model because like the beer can tank cars, it lacks a center sill and has no side walkways. He cut scale 11’3" from each end of the tank . The end result was a nice looking car although I would have gone further and replaced the plastic end railings with wire. There is no prototype drawing with the article so you’d be modeling off a model which I know some guys do not approve of. But any port in a storm.
Thank you for all your suggestions, recommendations and support.
I prefer to scratch build my rolling stock out of items I’ve found. I build my frames out of wooden stir sticks and regular and jumbo size hobby sticks; ice cream and tongue depressor size, found at most big box home improvement centers.
For the tanks I use various sizes of PVC pipe with styrene ends. If I need rounded ends I use spent CO2 cartridges of various sizes. I also fabricate loads out of pieces of the same PVC pipe and CO2 cartriges.
For car weights I got a piece of flat rolled steel; 3/16"x3/4"x36" and cut it to the specific length and weight I need. To fine tune the weight of the cars; to NMRA specs, I use BB’s. For the tankers I just put them in loose. For other forms of rolling stock I suspend them in two-part epoxy.
A while back I picked up a box of miscellaneous rolling stock detailing parts for $10.00. So I do have an ample supply. I buy my couplers in bulk and from the rolling stock I have refurbished I do have an excess of trucks that I’ve already paid for.
With these items I have managed to scratch build box-, flat- and tanker-cars along with gondolas.
In addition to the satisfaction I get from scratch building my rolling stock I can customize any car from the ground up rather than kit bashing.
When I enter these in contests, if the score is sufficient, the credits go to my NMRA Achievement Program.
I think we’d all be interested in your contest quality models built from those materials. Please post some photos so that we may learn from your techniques.
