I am using Derrell's drawings for my dimensions, so I've got that going for me...
Jim, to your point about the double taper - if it's your imagination then it may be mine as well and I'd have to agree. In your second image it looks like the near-end side stake (what?) looks tapered while the others are straight, though that may be an illusion. These cars, much like any car (especially narrow gauge), underwent repairs and rebuilds and became unique unto themselves. If we want to build a half dozen, we're likely to miss a few details particular to each car. Oh well... Here's a photo of 4360, from the 4246-4407 series built in 1902, all the stakes appear square (straight) and the u-bolt plates appear narrower and the same length, except the plate on the stake at the far left which appears a touch wider, perhaps from another car. Some of the stakes have extra bolt holes suggesting re-purposed stakes or narrower replacement upper side boards. A few of the u-bolt plates appear to have a highlight suggesting they were bent to fit a taper at one point, then pounded straight. Am I putting too fine a point on it? It's one of the things about this hobby (and this forum) that really appeals to me, this examination of minutia in the interest of historical accuracy. I love it! And a detail about the original 4090 photo that I just noticed this morning... the end grab iron - how it is bolted to the end stake and wraps around the corner and attaches to the side. Most likely an unremarkable detail, but I just noticed it and find it remarkably cool. I guess my point is: if I'm to make 3d models of these stakes, which do I make? Mike McKenzie |

Mike,
In answer to your question: "I guess my point is: if I'm to make 3d models of these stakes, which do I make?" I guess we Sn3 modelers need to step up and vote. I know of only one modeler who works in c1900 C&S in Sn3 and that is Bill Meredith at The Leadville Shops. Only two of us, Darrell Poole and myself, build c1909-1910 models of the C&S. (To be honest, Derrell actually builds models; I seem to just collect plans, parts and photos and then think about building models. ). Folks like Darel and Keith work in the 1930s. Per Derrell's notes on his plans, the end stakes on the St Charles coal cars were removed prior to 1907 (perhaps when the cars were converted to automatic couplers, c1903-1904). Folks modeling post-1925, probably shouldn't have any cars of this class on their layouts, as most of these cars (90) were sold to A. T. Herr Supply Co. in May of 1925, for salvage of parts or resale. My take is that you should design and print sets of side stakes for both classes of coal cars, the 1899 St Charles cars and the 1902 ASF cars (Derrell has produced plans for both). The lettering sets for both early classes of cars are available from The Leadville Shops. I would purchase five sets of stakes (including the end stakes) for the 1899 St Charles cars. I would purchase six sets of stakes for the 1902 ASF cars. Since these cars were rebuilt with 4" square stakes over the years, accurate models likely would require complete sets of both tapered and square stakes, allowing the modeler to follow photos of a particular car. Once drawn, the sets could also be scaled to On3 or HOn3 if modelers in those scales have interest. One other point, perhaps a mounting pin should be included on the back of the stakes, where they mount to the side sills, so the modeler could lay out mounting holes for construction. Perhaps if sets of stakes for both classes of C&S coal cars were available, The Leadville Shops would consider collaborating and produce laser cut wood components for the frame, floor and sides-ends. The wooden bodies of both classes of C&S 4 board coal cars were near identical in dimensions. Dr. Stears, what do you say??

Now that sounds like a plan. I can set up files for both and upload to Shapeways for pricing, then order a set to check for quality. Shapeways has the better pricing but the quality may not be up to what we'd all like. Their Extreme Frosted Detail plastic my fit the bill, we'll have to see. Certainly don't want people throwing money at 3d parts that aren't quite good enough.

Mike,
Just another thought: Why not set up three CAD files: 1. 1899 St Charles coal car stake set (including end stakes) 2. 1902 ASF coal car stake set (no end stakes needed) 3. 4"x4" straight stake set, for those modeling later years Each set complete with enough regular (8) and needle beam located (longer) stakes (4) per set. Thus each modeler can buy sets needed to mix and match square stakes as required for specific models. Consider 1 each additional regular and long stake per set to allow for modeling screw-ups. We will also need extra stake pockets for the St Charles cars, eight per car--I'm not sure that Grandt stakes are correct. Unfortunately, the St Charles side stakes seem different from the ASF 1902 flat car stakes (perhaps another project in itself). Jim

Here's where we're at with the 3d printed stakes...
I uploaded my first try of the tapered 1898 stake with 9 standard length, 5 long length and 5 end stakes, which gives the modeler 1 extra stake of each. This version had problems, some shapes were too small. Fail. So I went back to the models and made some adjustments, removing the washers on the NBWs and increasing the size of the nuts and bolts slightly. I used my PBL high-side stakes as a guide here, which are fairly bereft of detail but look great. This version passed the initial automated preflight, so we got that going for us... Looking forward to see how the Frosted Extreme Detail tun out. I placed an order for these stakes and I should have by September 2nd or so. I don't intend to put them up for sale until I see them. Price for the Frosted Ultra Detail (FUD) = 8.27 a set, Frosted Extreme Detail (FXD) = 10.61 a set. These prices are set by Shapeways, not bad though. I'll set up the other stakes when I have a chance, they should be cheaper without end stakes. I'll keep y'all informed as to how they turn out. Mike |
Thanks for working on this for us.
Looking forward to obtaining some coal car stakes and the Cooke domes when ready. Jim

Hi Men,
Here is a picture of an On3 model of a C&S 1898 St. Charles coal car, as built. The model was built 12-15 years ago based on Derrell Poole's coal car plans drawn in 1988. The jig to the right of the car was used to taper the stakes uniformly. Cheers, Randy |

Mike, thank you for stepping up and taking on this project.
As you point out I model in the 30s, and according to the photos in Volume 8, all the PI coals appear to have straight stakes. I figure I will build 6-8 of these cars. I was hoping to start with some PVC PII models, but may end up throwing out more than I keep. I may need to build one of my BLW kits to really see what I have to work with.

Please Keith, revisit your copy of ngPictV-8 and recheck those pictures. Also visit the wonderful photo's in Mal's C&Sng. You'll be surprised, a lot of Ph-1's had mixed straight and tapered stakes: look along the top-board for the thickness to determine this. I think I see #4307 on the ramp at Como having the most tapered (5/6) I've seen to note. PS Darel, talking of PH-1's......I haven't forgotten

I think the safest route which will also give you guys the best choice will be to develop three sets of stakes.
1) Partial tapered stakes with end stakes, with one extra stake each of regular, long and end. 2) Full tapered stakes with end stakes, with one extra stake each of regular, long and end. 3) Straight stakes, no ends, with one extra stake each of regular and long. If you want to mix tapered and straight that option is available, simply buy a set of each and that should take care of two cars. I don't know if anyone wants the full tapered stakes, but it's no big thing to set up. My only cost is time and I'm happy to do it. Now I have to wait for Shapeways to print my first order. The time it takes to receive orders seems to vary. I should receive printed parts today for a different job that I ordered last Tuesday, while the stakes order will take just over two weeks apparently (hopefully sooner). I'll let y'all know how they turn out, I'm hoping for good results with the Frosted Extreme Detail material. 3d printing has a real place in the hobby and things will only get better - quality will improve and prices will come down - but there is a chance the quality of these stakes won't be good enough, we'll see. I'll probably do On3 versions, I've had good results producing 3d parts in On3 used in the recent San Juan Decals (not SJ Car Company) flat car kits. Just a matter of re-scaling. I won't offer HOn3, the quality won't be there, sorry. Mike McKenzie (Drain Daily) |
Guys,
A couple of questions if I may... First, what is the status of these parts, did they ever get to,the point of being offered for sale? Second, the drawings by Darrell, art these drawings still available and is there a list of what car drawings are available? Lastly, I recall reading in the past that the C&S cars, or perhaps predecessor road cars used some odd or non standard timber sizes for the sills. If these cars were similar to the sizes used on other narrow gauge cars does this mean these other cars had odd size sills too? Do we have a list of the various sill timber sizes say for a C&S phase I coal car? Thanks for all this good information... Best, Todd Ferguson Harrisburg, NC |
Hey Todd,
The stakes were done in Sn3 and are available here: http://www.shapeways.com/product/TSAEZQTPA/c-s-1902-coal-car-straight-stake-set-sn3?li=search-results-1&optionId=57782898 and http://www.shapeways.com/product/3S69WJAEV/c-s-1898-partial-tapered-coal-car-stake-set-sn3?li=search-results-1&optionId=57782528 and http://www.shapeways.com/product/YNRBK2HE8/c-s-1902-full-tapered-coal-car-stake-set-sn3?li=search-results-1&optionId=57782627 3d printing is not as fine as injection molded plastic of course, but they came out pretty nice. Still need to do something for the older style corner brackets... Keith and Jim have been very patient so far... Can't speak to the availability of Darrell's drawing, you'd have to contact him directly. Mike McKenzie |
I have the stakes and the styrene set aside, along with a bunch on NY brake cylinders. What I am waiting for is some Phase II kits to start with.

Doug, Thanks for sharing the info. Am I correct in assuming the 1902 coal car is what Harry Brunk calls the Phase I car? I need to dig out my Robb C&S book!!! Also, wondering what couplers would be best for modeling the C&S in On3? Kadee, San Juan or something else? Best, Todd Ferguson Harrisburg, NC Sent from my Wacked and Cracked iPad III, OUCH!!!

C&S used full size couplers so San Juan are appropriate.

Todd,
Yes, I can do these stakes in On3. I model them at 1:1 then scale them down, so it's no big thing. Just a matter of finding the time! I'll try to get to it within the next week or two, if not sooner. Life is going to be getting in the way of model railroading off and on for the next several days through the weekend. I'll let the forum know when they're posted... Mike |
