Weekend Update 11/9/2014

Scott, you just blew my mind. How did you "scan" a real rock face?!
Last week, a guy that I coached with on my son's basketball team is a surveyor and he just mentioned to me that he has some kind of laser/photo setup to create 3D files of buildings. Maybe I need to ask him to go out to some of my favorite rock cuts!

...cast a lot of rocks including my new mold that came from a 3D print of a real rock face.

Looks good Jim. Looking forward to seeing your tutorial.

Glad you enjoyed the photos MC, you were missed. We enjoyed running on all your modules though! A big thanks to Steve, Spuds and Eric for making the trek to Roseville for the show with all the modules and to you and Rick for loaning out your modules.

My boys play on the same soccer team and were luck enough to have a 9am game on Saturday in Rancho Cordova so we were out of there and to the show as quickly as they could push me.

Nice progress on the HO layout!

Ryan: thanks for the photos of the Free-moN setup.
Wish I could be there, but both kids have 4 soccer games this weekend (one up in Sacramento, crazy enough) so wasn't able to make it.
At least Steve was able to take a bunch of my modules up!
And at least November in California is a lovely 65 degrees & sunny!

Ryan,  It was part of a project for work where we used a laser scanner over a few hours to map the rock face at different angles.  It was converted to a 3D solid and printed with a lab 3D printer. The advantage to the lab printer was that there was no limit to the details in 3D model and the resolution was very high.  While we were at it we used a conventional camera to do points by motion and it also worked.  It might be more practical since laser scanners are quite expensive.  Kind of over the top, but the section is neat and the mold of the 3D print was something I did at the end for myself.

I finished remotoring my brass Baldwin DS-4-4-10 with a Mashima 12x20.
The new motor is a bit tight inside the shell, but there isn't anything I can do about that.

During reassembly I installed a TCS Z2, which resides in the cab.
The engine could use a headlight and taillight, but I don't have sufficient equipment to solder magnet wire to the 0402 SMD LEDs that I don't even own.

The engine runs quite well, and it doesn't seem to have much of a pick-up issue.
I guess for once I not only completed a project, but didn't screw it up in the process.

Yeah, definitely over the top! But I like it
I will check with my acquaintance to see if he would do something like this. I don't have a place to print it...do you think Shapeways would be able to handle it?
Thanks for the info Scott.
