Every now and then this hobby of ours throws up some pleasant surprises.

one such turned up by courier from Shapeways in Holland the other day. Inside the parcel was a black cloth draw string bag (classy touch) containing a 3D printed bodyshell for a GE/Ingersoll Rand Boxcab diesel shunter. I had already got printed in FUD on Stonysmith's shapeway page but Walt, on his SouthernNscale page, had done one in 3D brass with nearly every detail printed in. It was stunning.



Like stonysmiths it was designed to fit the Rokuhan shorty chassis but being in brass there was the advantage, straight away, that the weight was going to transform the performance of the Shorty



There are some rasterization lines (layer lines) visible but to be honest they did not bother me much and would be a lot harder to clean up than a similar shell printed in FUD. The rest of the detail was very impressive with the radiators, grab rails and roof detail all present

Although Walt designed it to fit straight onto the Shorty chassis it sits too high if you use the locating lugs on the chassis so I cut them off and added packing pieces on top.



extensive track testing on 'Hakuho' did show that it tracked really well and would pull a decent amount of stock. there is enough space above to fit a decoder and lighting board

Seen doing the job I had in mind for it , working on the forest line

Now I don't have the heart to paint it yet. So I'm going to leave it unpainted for this autumns shows and run it just to show other modelers just how far 3D printing is going.

i know that some of the guys in the USA are already planning on doing one of these in the New Jersey Central livery the preserved prototype carries

Amazing.

I guess brass printed stuff is more sturdy that plastic for fine detail?

Latest

Chichibu Railway (An Industrial Limestone railway in Japan) DEKI 500 electric. Again made to fit the Shorty chassis



Once I've got the shows out of the way I'll start looking at what Pantograph to fit

Real railway here

Chichibu railway

I've managed to get enough info to have a go at the Limestone hoppers with their distinctive brake cabs built into the hopper ends


I've also got the 3D printed Brass chassis to fit Walt's Fairbanks Morse switcher which takes all the bits from a Shorty chassis and extends it.

Looking at it I'm already thinking about doing a Class 20 using the same technique

more soon

So this is the 3d brass chassis from The Z maker designed to take the components from the Shorty chassis. It was a really simple conversion and the only blemish was I got the motor wires the wrong way round and it goes backwards! Seen with two 'Failure' bodyshells



As the bodyshells printed in FUD, or whatever they cal it this week amd cost less than £10 they are cheap enough to mess around with until you get it right


I finally painted the boxcab. I didn't do it in its original Central New Jersey green as that would tie it to one time and place so chose a generic green (Hycote Ford meadow green) as the loco can work the highline on Republic Steel, the dock on Cuyahoga and the forest line on Hakuho



needs a little touch of weathering



Painting sequence was left to soak in white vinegar to etch it for about 30 minutes. two coats of Hycote self etch primer. Two coats meadow green and one coat of Hycote gloss lacquer. Left for a couple of evenings and the running numbers aded and grab rails picked out in tamiya yellow and a final coat of Hycote matt lacquer
