Second Place fFreight car from the NNGC

Modeling Rolling stock
#1

My model of Rio Grande Stockcar #7403 won the Second place in the Freight car Modeling contest at the National Narrow Gauge Convention this past week, and i thougth i would share some photo’s with you. As displayed

Truck Detail

Brake Cylinder detail

Model is completly scratch built. only comercial parts ar Bob Hartfords Bettendorf Truck side frames and detail kit, and brake clevises, and various mfg’s NBW castings. the brake cylinder is a new casting of the correct size cylinder, the wheel centerswere spin cast, tires and axles were turned on my lathe. all the new castings were designed in 3d in a program called Solidworks and the files used to create Rapid prototype masters. the base carbody was laser cut from my own 2d autocad files. the photo etched components were made using Micro Marks Pro Etch. also note the cotter pins in the brake rigging. Enjoy

Yea! Way to go!

EDIT - that is ODD - first trip to the page, no images, just the links to them,
Wrote and posted this message, then while message was printing pictures showed up.

The pictures are huge but displaying fine for me.
Congratulations, Al. A beautiful job.

Forrest,

my first use of the freight sheds feature, realized the issue was spaces in the file names, and i fixed. thats all there is to it

#5

Wow, great model!

#6

My word, that is just gorgeous. Lots of work in that one and it turned out very nice.

#7

thanks for the kind words. belive it our nor it runs just fine on my layout which includes 5ft min radius curves, with the full brake rigging in place.

#8

fantastic build, congratulations

#9

Al,

Stunning model!!

I have been considering the same technique (solid modeling package and rapid prototyping). If I am not being too nosy, about how much were the rapid prototypes? I can guess from the pictures how many.

Wow, that is a BEAUTIFUL model! Great work! Congrats!

#11

Looks about ready for the fall stock rush…:wink:

#12

Nice
:slight_smile:

#13

Nice! Nice! Nice! A beautiful car for sure. I can’t help but wonder what could have possibly beat it out for first place.

#14

Wow, looks real! I was wondering the same thing that Richard did, what the heck beat that out for first?

#15

Well i do not have a picture of the 0n3 D&RGW drop bottom gondola that took first place, my opinion is that it fell under the “local favorite/modeler” classification. will have to wait to see picture in Gazzette. as to the cost of the Rapid prototypes let me say that they are expensive, but i plan to build at least a half dozen variations of the same. the underframe was used on boxcars, stockcars, flatcars, refigerators and gondolas. these parts will be avalible thru hartford products in the near future, the trucks are avalible now. the trucks are also sutable for truss rod C&S / RGS class 2 cars.

I use Solidworks at work (poorly) for simple shapes it’s great for me but I’ve got trouble wrapping my brains around the more amorphous shapes we sometimes design. I’m working up to it but the lerning curve is tough on your own. We rarely do rapid prototyping though.

Nice work on the car though!

There are several guys experimenting with rapid prototyping over on the Finescale forums, including some comparisons of different processes/services. Also some good discussion on using the software, etc.

#18

ANOTHER forum? No thanks!
