Alco PA

Alco PA

Postby j p » Sun Mar 26, 2017 9:20 am

Jes made a very nice shell for Alco PA. I bought his model from Shapeways.
I tried to find suitable trucks and drive for the engine and found Tillig's BR103 close enough (Kuehn's BR103 could be another option). Maybe not 100% perfect, but within my tolerance. The trucks need new (smaller) wheels.
The frame needed some extension and adjustment for the fuel tank.
The pictures show the shells, the frame, the trucks, and comparison of BR103's and PA's sideframes.

Pretty cool. You guys in Europe get MUCH better quality out of shapeways. Keep us up to date on the build!

It starts looking as a locomotive.

Great project! Can't wait to see this loco up and running. BTW--how do I get a PA shell like yours? :drool:

Hi Pat!
It's from Shapeways-
https://www.shapeways.com/product/NPBN4 ... d=60322648

If you do decide to order one, check it out carefully when it arrives! Jes has done a great job designing them, but sometimes Shapeways quality control is out in left field. If you get a bad one contact them, they will make another one (and every time they have done it for me it's better!).

Has anyone in TT'dom attempted to 3d print a loco shell on his/her own 3d printer? I've seen stuff printed from Shapeways, but I'm wondering if there are any $500 or less 3d printers out there that can "print" diesel and steam loco shells/parts on one's own kitchen table? :think:

For $500 you are going to be very far from acceptable results.

For quality shells.... You are missing a -zero-... $5000

I HAVE signed-up to receive the long-delayed ONO 3D printer... https://www.ono3d.net
which has a maximum 2.8 by 4.8 in build area...

The ONO sits on top of a user-supplied smart-phone... and uses the smartphone screen to image and fix liquid resin.
This means that the x-y resolution is whatever the screen resolution happens to be on the smartphone you provide.

If it works as-advertised... it could be useful for small runs of TT-scale parts, such as doors, ends, etc... and even oddball truck side-frames (Chrysler?, Caboose?, Vulcan???)
