Jawn Henry

[propmeup1]

Think we'll ever see a N Jawn Henry ?

The RSD trucks from an Atlas C628 would make it a whole lot easier to make than the C&O steam turbine.

Are you going to make one?

[Mark5]

Up to now I only thought we'd see it in brass. But who is making brass these days?

I imagine that sooner or later, virtually everything in the historical record will be done in 3D printing, you'll just need to figure out a mechanism.  I never figured to see Baldwin DT-6-6-2000s, but that was among the first shells done on Shapeways. 

[Mark5]

When the shells get better than the crap on Shapeways, I'll be interested.

Eventually the frames, and gears, will be 3D printed, leaving only the motors, and possibly the wheels, to be made in traditional ways.  It's just a matter of resolution.   They could probably print frames today, with some of the metal-filled materials.

I know. Wish they would just offer the files for sale. I could pay for the file and have it printed by the next day. And it would be a better print... with no crystals to boot!

No argument there.  One of the things holding us back on using RP in modeling is that Shapeways has what seems to be "old" technology.  But even with that said, the most recent Shapeways parts I have (from Keystone details) are several orders of magnitude better than the first ones I ordered (that Baldwin shell being part of the first order).
It won't be much longer before we  will be able to pick up a high res printer at an office supply for 500 bucks, with readily available parts, and vastly overpriced resin in little containers (ala a laser printer nowadays).  And not long after that, there will be a $99 version on the shelf at Walmart.

Back in 1988 Pete Peters of the S.D. SONS was building one with a pewter shell and a radiation depleted heavy metal chassis to compete with Jim Fitzgerald's Cotton Brute in long train pulling contests at N Trak conventions. The contests fell out of vogue and so he set it aside for other interests. I've seen it, and it was 85% complete, I cannot say if he ever finished it. He was also in his 70's back then, so I cannot say if he's still around today. The S.D.SONS would know........

Whats the grudge against Shapeways..... if you clean/gridblast/prime their prints properly they come out nicely detailed and smooth.
Having the print orientation right and as many flat parts as possible also helps.
Its not injection moulding but you can have/make/buy models which are not available otherwise.
Their Projet 3500 HD Max printers are good machines and cost a bundle.
If you want to invest yourself, buy an Anycubic Photon S for $450 or a Formlabs Form 3 for $3000: they also produce (in my opinion) decent prints.
I have a lot of brass N scale ATSF models but I think no one will produce another new N scale model in brass and  nowadays 3D printing produces much better N scale models than 20/30 year old brass 20/30 and at much more affordable prices.
The biggest remaining problem for engines is finding/making/adapting the correct drive train...........

Happy N scale modeling........... Dirk Blikkendaal........ ATSF N Scale Models.

Was this built by Baldwin? Because I feel like a locomotive named Jawn could only have been built in Philly.

Yup!

Because they can take up to around a month to get parts nowadays. And I'm perfectly happy wit the detail of FUD, but over time (less than a year) it starts to form crystals. Something they can't explain.

[Ed Kapuscinski]

Yup!

Hahaha, awesome.

Dirk, et al....

I've seen several people mention use of "grit blasting" or "sand blasting" to rid Shapeways models of their artifacts. What product do I need to use to do this without damaging louvers, and similar cast in detail?  And what filters do I need to keep this stuff out of my lungs, spray booth motors, etc. (cause anything small and fine enough to not take off detail is going to be inherently dangerous if inhaled and make a mess out of ball bearings- etc).
