Thanks David, As a modeler modeling an era where stub sill tank cars are the norm, I'm not up to speed regarding the nomenclatures for the different type of frames associated with older tank cars.

G'Day to you Darrail I cannot tell you with certainty what under-frame was used on 168. When I was much younger I was well acquainted with Stanly D. Grace the son of the founder of the John H. Grace

The underframe is a typical ACF Type 27, as is the tank. The vertical rivet rows are for the internal bulkheads that separate the tank shell into two compartments. David Thompson

Hard to believe I am sure but I am not planning to model either a builder's photo or a train wreck. Bill Welch

There is still a problem with banding, very visible on the end doors of the lower two ends.. Not a problem is used for resin masters, but not ready for prime time without a lot of sanding. Cory's Utah

Tom Maddenwrote (in part): This reminds of what printers used to say to publishers, who naturally wanted the very best deal in every dimension: "Quality, speed, price. Take your pick." Tony

I believe Corey Bonsall, who does the D&RGW and Utah Coal Route gons, uses a Form 2 "upside down" SLA printer where the part is built from the bottom up as it's lifted, layer by layer, out of the

Eric, Bill can always 'model' a wrecked car laying along side of the right of way ... that way the under body details will be easier to see. *W*

Maybe whitewash them as if a car set up for a builders photo was not repainted. Then it would be quite visible. 😀

I see that that round "apartment building" is in the background of the photo I submitted. Ed Edward Sutorik

The truss rods and turnbuckles look great, Bill. Seems a shame to hide this work in the murkiness under the car. Eric Hansmann Murfreesboro, TN

... Of course you can't find them because they were Utah Coal Route cars... Geesh. Link to message with pix Dennis Storzek

Thanks Tom, very informative. This proves to me that Shapeways is just maxed out and still found wanting. It's no longer an issue of resolution, but designing around the "wax tracks". It seems the SLA

I've put together an explanation of why the "corrugations" are present and how 3D printing of highly detailed vertical surfaces is still problematical. (Sort of a warm-up for my Cocoa Beach clinic.)

G'Day Gents, I'm always on the lookout for photos of steam era freight cars that will fit my August - September 1979 timeframe, and the other night, I came across this photo of a GYRX

Thanks for sharing Ted Fenton

Yes, it is. The one I photoed was on a storage track in the B&O’s Indianapolis Belmont Street yard in late 1969 (I was home from college and on my way to a nearby hobby shop). It was in much
