Shapeways report
Tom Madden
On September 8 I wrote:
I've submitted a part to Shapeways to be run in the Frosted Ultra Detail (FUD) material Kent mentions. It looks to be 3D Systems' multi jet process, which is similar to the PolyJet process I have access to. The part is a heavyweight Pullman bolster assembly, the design is visible here:-------------- The parts were finished and shipped on Wednesday 9/19, as advertised. I received them the next day (yesterday). To reiterate, here's what the design looked like: http://www.shapeways.com/model/694311/bolster2.html?key=a29def8060cf357026fd64e7f1847f40 And here's the part: http://www.pullmanproject.com/Shapeways4.jpg Not bad at all. That photo shows the part cleaned and primed so you can see the surface. Here's a photo showing one part as received, and the other all cleaned and degreased: http://www.pullmanproject.com/Shapeways1.jpg The glossy substance is residual support material, and there was a good bit of it down in the cavities and corners. It's wax, but I didn't want to heat the part at that point so I tried a succession of ultrasonic cleaning steps. First was with water only, then water with a shot of Dawn dishwasher detergent, then Chameleon paint stripper, and finally 70% rubbing alcohol. Each worked to some degree, judging by the clouds of debris issuing from the part at each stage. At the end, the part was pretty clean and heavily frosted. The remaining debris down in the cavities in the center sill was easily removed with a dental pick. I'm not suggesting this as *the* cleaning sequence, or even *a* cleaning sequence. I just wanted to start with the least aggressive cleaner and work up from there. The frosted appearance may be due to etching of the acrylic part by the alcohol, or just the appearance of the material itself when fully cleaned. (It *is* "Frosted Ultra Detail", after all.) I have one more to do but want to show it at work before I clean it. These next two photos show the part after a light coat of gray primer: http://www.pullmanproject.com/Shapeways2.jpg http://www.pullmanproject.com/Shapeways3.jpg Coverage within the cavities was incomplete, as anyone who has tried to spray into a small, blind cavity will understand. It did give an interesting optical illusion as shown here: http://www.pullmanproject.com/Shapeways5.jpg The vertical cavities look like they have tapered walls, but I can assure you the walls are straight to the very bottom! OK, some specs. I measured the overall length, from the edge of the vestibule floor to the tip of the mounting tang, the length of the "center sill" portion of the bolster, and the overall width. Here are the dimensions, with the design dimension shown first: Overall length: 2.128", 2.135" Center sill length: 1.465", 1.470" Overall width: 1.223", 1.223" Width is dead on, some "creep" in the length. Still, not bad at all. There was a bit of "cupping" of the vestibule end of the part across the width. (The right end as shown in the photos.) These were the portions of the part that were relatively weak, in that there were no big gussets leading from them. I got rid of the cupping by heating the part in a microwave (33 secs on high), which softened it enough to let me hold it against a flat surface until it cooled. That was after cleaning but before painting. It has stayed flat. I had run this part on our PolyJet machine, albeit in its low resolution mode. The PolyJet vertical walls were really rough. The vertical walls on the Shapeways part were surprisingly smooth. Actually, astoundingly smooth is more like it, with very good definition of details on the vertical walls. The lips around the apertures in the side walls (the apertures go all the way through on the prototype, but that would be an impossible part to cast) are very well defined, whereas on the PolyJet part, if you didn't know they were supposed to be there, you wouldn't see them. There is much less stairstepping on the "off-horizontal" surfaces than I expected, but there is some. There is also stairstepping evident on the non-orthogonal flat vertical surfaces of the tapered crossbearers, but not on flat vertical surfaces aligned with the X & Y axes of the design. Particularly impressive are the vertical walls of the cavities, and that little curved portion of the top of the bolster. I think this particular process is perfect for models of foundry cast parts, like this bolster pan. Such parts are tough to scratch build, with their blended surfaces and coved corners. The surfaces of the FUD part have a slight granularity which adds to the casting effect. The key to successful use of any tool or technique is not to ask for more than it's capable of giving. Really fine detail ("The Full Culotta") is beyond the capability of Shapeways' FUD process. On vertical walls, impressive as the ones on my part may be, it would be prudent to leave off all but the coarsest details and add them later. And the waxy residue issue no doubt comes from Shapeways' keeping costs under control by using "one size fits all" secondary processes. Don't expect Shapeways' staff to spend any time critiquing your design or offering suggestions for improvement - if it passes their up front screening process, that's what they'll make, even if there are design flaws that render your part unusable. They will suggest a process and material, but the ultimate choice is yours. Learning and applying 3D CAD tools is not for the impatient, but the rewards and satisfaction are great. Holding a part you designed in your hand is a real kick! I can't wait to submit some more parts. Standard disclaimers apply, not connected with Shapeways in any way. In fact, they're really a competitor! Tom Madden

Re: RC SOO DD
Tom Madden
Ted replaced the side sills with deeper ones, and left the hand brake off his model until the correct Klasing brake wheel becomes available. He also used InterMountain's ASF trucks. If you find a set of his doors the package should contain an instruction sheet telling all of this. Or, as Brian says, get your hands on Prototype Railroad Modeling Vol. 2.

All I know for sure is that I'm giving an updated version of my Santa Fe "Fast Mail Express," talk, illustrated with my efforts to model representative train consists from 1947. These include express box and refrigerator cars, for mandatory almost freight car content. I don't have the schedule from Joe, yet, either, so I don't know when I'll be presenting. – Andy

B&O C16 Decals
Bill Lane
In the past week or so I been working with Jerry Glow to make some B&O C16
(M53 in express service) decals for me. http://www.lanestrains.com/B <http://www.lanestrains.com/B&O_C16_Express.jpg> &O_C16_Express.jpg We are done. I am just waiting for my order now. If you are interested in getting some of these new sets please contact Jerry directly. jerryglow@... Jerry will make them in whatever scale you want. Mine were sized to a S Scale urethane M53 kit. I gave Jerry the spacing between the ribs. You may want to do the same to ensure a good fit. We also recently did the N&W G3 gondola to fit on my PRR G26a cars. From first contact of requesting the set to be made for the G3 to having decals in hand less than 3 weeks total. I am expecting the same for the C16. Usual disclaimer - I have no financial gain here. I am just a **very** satisfied customer that Jerry made these sets for me in such a limited quantity for a very reasonable price. I am just trying to help Jerry hopefully get more sales on the sets we made. His list of available sets are here: http://home.comcast.net/~jerryglow/decals/decals.html Thank You, Bill Lane Modeling the Mighty Pennsy & PRSL in 1957 in S Scale since 1988 See my finished models at: <http://www.lanestrains.com/> http://www.lanestrains.com Look at what has been made in PRR in S Scale!

Re: Naperville
Clark Propst
Joe has the event schedule up on his website, but no speaker list. The list in the on-line magazine referred to here must be from last year. I talked to John Golden, he's not doing one, also doubt if Stan Rydarowicz is either. I asked him some time ago if he wanted me to do a new Power Point show for him, he wasn't sure what he'd do. Maybe he got someone else to do it? Doubtful...

New Intermountain 42' flats - CofGa
Lee Gautreaux
I see that Intermountain has just released a 42' fishbelly side sill flat decorated for CofGa:
http://www.intermountain-railway.com/reservationflyers/RF0912HORCFlatcars.htm I have found that the CofGa 11101-11140 series flats were actually rebuilt from their 17001-17200 series gons. http://www.railgoat.railfan.net/other_cars/cg_cars/cg_number/017001-017200.htm However, Intermountain offers the cars numbered for some numbers above 11140. I list 30 cars above those in two series that appeared at some point during the 1950's as follows: 11141-11155 50'-0" 50 ton 11156-11170 42'-6" 70 ton I guess the numbering was just an oversight. Does anyone have info on the two above series of flats? Lee A. Gautreaux - The RailGoat http://www.railgoat.railfan.net/

Modeling this combo would be an excellent reuse of a poorly detailed heritage model (the PT) and a great fit with my current rail marine interests. The Tichy 40' flat might be a starting point for a dice & splice conversion but I'd like a straight kit build if it is available.
