Wow, cool looking etching. I've looked into getting an etching setup for a bit but haven't yet pulled the trigger on it. What do you think of it so far and which kit did you get?

My wife bought me the Micro-mark kit. It was very easy to use, and the instructions cover everything you need to know. After one misfire, due to me not following the instructions closely enough, I had success. And the second time around was much easier and quicker as I already knew most of the steps.

I would say the most time was actually spent creating the artwork. I used a combination of Adobe illustrator and Solidworks ds.

Almost have my first piece of motive power. All that's left is paint, lights, and sound. It was definitely a fun experience. This is the first kit I've ever done like this, and I ended up modifying it quite a bit to match the prototype, also a lot of fun! I made the cab roof removable in case I want to add an interior at some point.... Let me know what you think!








The next shot really highlights the narrow gauge!

Nice job on the loco and the etching! 

How thick is the sheet, and how long did it take to etch through?

Thanks Herb!

The brass was the .005 inch thick sheet that came with the etching system. It took about seven minutes to etch completely through one side, and I just dangled the unfinished side in with the pair of plastic tweezers for about two more minutes to complete it. Believe it or not, folding the dang AC unit without deforming it was the hardest part of the etching.  All the soldering except for brass to brass was done with cerrosafe. I made thin soldering "sticks" by ladling a thin line of it out on a sheet of glass.

Well--an old dog learned a new trick!!
 


Been soldering for about 70 years--my dad was a tin knocker, and showed me early how to solder-- but I never tried soldering with any of the Cerro alloys.

Great idea---THANK YOU!!!

Well I can't take credit for the idea. Railmaster (the kit manufacturer) recommends a low melt cerro alloy for soldering the pewter parts together. I did come up with the idea to create the sticks though, works really well. I used stay-bright acid flux, soldering REALLY speeds kit construction, plus it makes filling gaps and fixing mistakes a breeze. I did use JB Weld for a few details that would have been difficult to solder, it is as durable as solder, plus you can solder right next to it and the heat won't bother it unlike epoxy and CA.

Good job on the loco mate:thumb: There's gotta be a special blessing for someone who runs Alcos:P

For those who were wondering, that's an Alco/MLW, originally built for the White Pass RR.


Just a thought, why not make a master and cast the dump cars in urethane?

Thanks moss!  Yep, there's just something about those Alcos...

Yeah, probably the best way to do the hopper cars is by casting. I'm going to need at least a half-dozen of them, so in the end it will probably be faster, but that means I first need to learn how to cast in urethane. I originally considered doing them with etched details and brass shapes, but it would likely take forever. So I began the water car in the the meantime. Since I only need one, it makes sense to just do that one in brass.

That loco is very cool. Nice to see someone take the time to do something unique.
