C&S 911

[linnwm]

Not sure if I am allowed to "advertise", but I have a model of C&S 911 business car on Shapeways.

Now that's beautiful!

Is it possible to scale the printed car up to S scale (1/64 scale)?

Whats the upside advantage in printing the car in "Frosted Extreme Detail" vs "Ultra Detail"?
Is it worth the extra $40.00?

[Robert McFarland]

How about a DSP&P Pullman(as originally built) in On3,Sn3,and HOn3?

Not sure if I am allowed to "advertise" . . .


You keep coming up with printed C&S passenger car bodies in HO and S scales, you can post here as often as you like, as far as I'm concerned!

There are so many C&S cars needed in all scales: Baggage cars, RPOs, Combines, RPO-coaches.  

Unlike all the D&RGW fans that have multiple choices of brass imports and now Blackstone J&S coaches in plastic, we C&S folks only have C&S coaches 70-76 in O, S and HO scales and only RPO 13 in S and HO scales . . . that's it, all relatively rare brass imports from Overland from years ago.

Ken Martin has a great book of plans for all the C&S passenger cars, and I'll be happy to send you a copy of the C&S Passenger Car Folio to get you started (hint, hint)

I may have to buy one of your HOn3 business cars, just to satisfy my curiosity!

[Robert McFarland]

Don't forget On3.

[Jim Courtney]

That's a good question, Robert.

How does larger scales impact the 3-D printing process?

Is the mass of material required for an On3 (or even Sn3) passenger car cost prohibitive?

Looking around on Shapeways, most printed passenger cars are HOn3 or even Nn3. Do such large bodies in larger scales introduce warping issues?

[Keith Hayes]

Jim, don't forget the Cimarron resin kits for coach 62 and Business Car 610 based on a Pullman design. I have these two kits in the cabinet waiting for a future build.

I have not evaluated the difference in the Shapeways materials. I have found the lesser cost material sufficient for my purposes. The chief issue with larger scale is the sheer size of the model. If small features like the sills rendered well in HO, enlarging the model should not be an issue--it may be necessary to check the wall thicknesses--these may be able to be reduced in some cases.

Some baggage cars, and a model of RPO 10-12 would be nice. The latter are more difficult due to the arch top doors and windows and the broad quarter round trim at the openings.

Linnwm also has some neat HOn3 C&S switch stands:  https://www.shapeways.com/product/JYHT3LWM7/slide-switch-stand-cored?optionId=63646609&li=more-from-shop

PRODUCT DESCRIPTION
6 C&S switch stands cored to slip over a 0.118" square slide switch handle.


A nifty idea to allow manual control of the switch, complete with electrical contacts.

Hmmmm . . . if only they were printed in 1/64 scale.

[linnwm]

Most people say there is little difference between extreme and ultra. I believe the difference is in the Z axis having thinner layers. The car in the photo is ultra.

HO scale seems to be the largest practical size cost-wise for a complete model in the Frosted Ultra Detail material. S and O would get pretty expensive though it is possible that scaling up would allow the car to be printed in the strong and flexible material, which is less expensive per a given volume. Same could be said for the switch stands, though they are designed for a specific size button. I am not sure what the minimum throw is for S and O. Might need a larger slide switch. Obviously, they could be used without a slide switch.

Maybe I'll fool around with 911 for S and O and see if it is practical. I hope to continue making various cars that have not been available. An EBT boxcar is being printed as we speak, and so far it looks pretty good. We'll see.

I know that On3 and P:48 point throw are available on line in the NMRA Standards and RPs. I believe that the same holds true for S/Sn3.

What about separate sides ends roofs and floors.

[linnwm]

Printing separate sides could be advantageous provided they can be connected and printed as one part, if the x/y area is large enough.
