Looking good Chris !! Remember Cliff has almost finished his mine 6 months ahead of schedule

When it comes to deadlines, I prefer Devon’s approach.

I love deadlines. Especially the whooshing noise they make going past.
I have the fuel tank all together and primed. I have a couple of minor details to add but it is mostly complete.
Tank itself is 3D printed ABS plastic on a FDM style printer. Sanding and filler primer removed the lines with the exception of a few on the very bottom that you cannot see anyway. Top sheets are .020" styrene. End sheets are laser cut .75mm acrylic. All the rest of the details are 3D printed detail plastic from Shapeways.
The vent pipes will be glued to the underside of the frame when the final installation happens.
The mounts, waste tank and drain bar all pierce thru the acrylic end sheet and into the printed tank.
Tank assembly mounted to the frame.
The tank is screwed to the frame. The drain block will be plumbed to the waste tank during final assembly.
Probably be it until it gets to cold to work outside.
Thanks for looking,
Chris
I hope I’m still allowed on your thread. (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)
That looks fantastic Chris.

Of course, I haven’t achieve the Rock Star status you got from the wide body build.
Nice Work !!
very cool
Rained today so no layout work. Instead I put traction cables on the SD40N.
This is how they arrived from Shapeways. Each print represents one side of the locomotive. I designed a support structure as part of the print, which also helped it survive shipping. To get it to work they are split at the bolsters, and then a gap in the center. I had planned to fill the center gap, but that didn’t go as well as I thought. No worries, that space will be hidden by the fuel and air tanks.
Here are a few random shots of them installed on the frame.
Thanks,
Chris
this is really cool!
Did a little body work tonight, cut the nose off so I can make a new one. Here is what it will look like when extended out.
Damn it Chris, your not making it easy for me. Now I know I should add traction motor cables to my GP30 build when ever I get back to it. How in the Heck have you found so many up close detail photos to go by? Or are you just guesstimating the locations?
Don’t blame me Craig, it’s all Shane’s fault! Every time I add a new detail part he puts up a thread of a whole new loco he built!
I actually found a layout of where the traction cables are supposed to go on a SD40-2. Got really lucky on that. I followed them as close as possible on the model. In the end, probably be something most people won’t notice.
Most people won’t know or care, but weirdos like us enjoy those kinds if details…
These threads are not helping me. Currently my new garage is full of crap from moving. 1st priority is getting a workshop set backup.
Nose is designed and off to Shapeways. I also have filters, tank drain valves and chain brackets coming. Unfortunately they won’t ship until Dec. 10.
Currently I’m finishing up the new air tanks and ready to start the air plumbing. I also have 3D printed step light housing to install and my new truck mounts are being printed.
With the short daylight hours after work combined with cooling temps will get me back to working on this build.

The man speaks the truth as I currently blame Shane !!
My new nose arrived today. This one is the correct length for Union Pacific locomotives and is the type that uses a brake wheel. I made it to interface with the body in the same way the old one did.
What type of material did you use for printing? Doesn’t look like FUD (or what ever they call it today)? Looks like flexible plastic that has a bit more grain.
Looks like strong white flexible to me. Anyone tried this product to help with smoothing the grain out? http://a.co/d/eL1TMPh
I printed the nose in Shapeways basic white plastic, which does have a slightly grainy feel. It’s not to hard to smooth that out by sanding and then finishing with a little filler primer. I have been using the fine detail plastic on my small parts because they do come out nice and smooth, but Shapeways wanted $180 to print the nose in that material.
That being said, I printed the nose complete with all of the details, which makes sanding a bit more tedious. I am also a bit worried about blending out some of the details with the filler primer. Lucky for me, I screwed the nose up and made the brake wheel to low, making a correction and a new print necessary. I have redesigned the nose to remove the details and put pockets in the location where they go. This will allow me to print the bulk of the nose in the white plastic at a cheaper cost. I can also sand with no regard to removing the details. I will print detail pieces out of the better plastic and then glue them into place once the nose is smooth. All of this will still cost 1/3 of printing the whole nose in the better plastic.
Below you will see the new modular design. The gray will be the white and the rest of the parts will be the detail plastic.
