Great detail Bob! Looking very good.
Will you print these parts in brass? Or due to the detail must they be printed in FUD or FED?

Thanks Håkan, The pumps have to be FUD for thr detail. And I still lost some. I'm trying to get the targets and throw arm done in Brass but Shapeways is balking.

Hi Bob,

I don't know anything about building locomotives, so I can't asked questions about that. I do have a Shapeways question thou if you don't mind. Are you only get a single part printed at a time? Does it cost less the more parts you print at one time?

Thanks,
Rob.

Sorry to be slow at getting back to you Rob but I was out of town for a day. I try and get as many parts as I can printed at the same time so that I can save on shipping. On the other hand though I don't want to delay progress by being cheap.

Hi All,
I got a shipment from Shapeways today.
Here are the side rods and other parts in Brass;

I'm pleased with how these came out. The thin parts picked up some curves that will straighten out easily. I might have to do the Main Drive rods because the eyelet on the neck end might be too small.
I'm also very happy with how the prototype pieces came out. Here's the running boards;

I'm very pleased with this prototype print. the detail came out sharp and the FUD is strong enough to handle handling and minor "incidents" but not a 48" drop into the Royal Grande and it's concrete bed(neither would brass). They also revealed a new wrinkle. My drawing was of one piece. All the checks I ran and the computer checks and models at Shapeways showed 1 piece, but when it printed I got two with the print separating where the components joined together. Here's a shot showing how they fit on the latest Boiler prototype.

These running board came out a little long and need some adjustments in the cab area to match and join the boiler and frame castings.

Next I would like to tell about a exciting product offered by DAVE'S MODEL RAILWAY STUFF.
He offers a set of wagon wheels;
https://www.shapeways.com/product/CS56UKPKA/wagon-wheels-assorted-ho-scale-x16-plus-pulleys?optionId=56254160
In FUD for 11.16, you get enough wheels for 4 wagons.

Here's a picture;






That's all for now.

The rods looks great as does the other parts! Like the fit of the running board to the boiler.
I have to check out the wagon Wheels. Thanks for the link.

Thanks a lot Håkan, I greatly appreciate the encouraging words. Shapeways shipped the Crosshead Yoke today so next week I'll be able to do some final fitting of these pieces.

I got more goodies in the mail today. Compare the drawing at the top of the page with this FUD print of it;


They are FUD so they'll break real easily but at least they're cheap. The throw arm is too thin to cast in Brass with Shapeways process.

Here's the other item, The Pumps;

As you can see these have some problems. In printing the arms and parts went a bit out of alignment. These will be glued to the Crosshead Yoke which will be Brass when final. The Yoke should holed the pieces of the pump square. I do plan to beef up the pump's design though. They're absolutely in scale right now and also can't be printed in Brass.I might make them a tiny bit large so they can be. When I get the prototype Yoke in I'll be able better to know what I have to do.

Enjoy

Very nice Bob! On the targets, try to dip them in thin ACC before you paint them. It helps strengthening them.

Right on target there, Bob. Another bullseye. Good stuff.
