Bob,

Looks like you’ve mastered Sketch Up, especially if you can pick it up smoothly after being away for a while.

Thank you Mike. I don't feel like a master. More like an apprentice blacksmith who is just pounding away tell it looks right.

I'm with Mike: Looks like you've gotten pretty salty with Sketch Up!

Thanks Andre,

I change some details and added others. I had to adjust a few walls as they were too thin for Brass. This was the final design:



I submitted them earlier this evening and to my surprise I just received a E-mail telling me they passed the human checker. They promised them by March. They most likely won't take that long. Shapeways has changed their pricing. They now charge a minimum order for small orders and surcharges to expedite orders. It will change the way I deal with them. I will group together as many prints as I can. That will save me on postage too. These crossheads will be the last brass casting I'll need [I Think]. I need to do the lead truck frame but I'll try Shapeways new Plastic for that. That will lessen the possibility oF shorts. The crossheads and all drive rods will be nickel/silver plated.

Bob

I was having trouble with one of NWSL's gearboxes. The Idler gears had a dead spot in it from misformed teeth and in the process of Trying to fix the blind spot I destroyed the gear box. The gearbox was also giving me trouble because it was too tight on the driver axle and I didn't know how to handle that. Well, NWSL has an idiot guarantee (they call it a disaster plan) in which, they will replace what you screwed up. So I took them upon it and a week later I had new parts in the mailbox. In the meantime I was researching and asking around about how to fit the gearbox. Today I was finally able to work on the new gearbox but when I assembled the gearbox around some 1/8" axle stock I was delighted to find the axle stock spinning freely. Apparently NWSL had improved the product since I bought the gearbox.

Thank you NWSL.

Bob:

What gearbox did you settle on? What ratio?

Eventually I will be needing to use a gearbox from some of my steam kits (Arbour) and projects.

Thanks.

Thanks for the info, Bob.

I'm looking forward to your impressions about its running characteristics once you reach that point.

Nice drafting Bob. I believe Shapeways was sold recently.

Thanks a lot Frank. I do appreciate it.
On Shapeways, I don't know about their ownership. They started adjusting their business pro folio for about a year ago. The first thing they did was change their shipper to UPS/USPS which just added a day to the service. About six months a go they change the names of their materials and eliminated others.
I guess they didn't like people using the acronym FUD so they renamed it to Fine detail Plastic. I'm going to start referring to it as unFud. The materials they eliminated were IMHO inferior materials that I don't miss. Then in December came the price changes. They are not the only printing service out there and the changes have not annoyed me to the point that I'm think of dumping the Devil I know for one I don't.

Why do New Yorker's always get greedy?

So much great information in your recent posts for me to absorb as I slowly plan a locomotive build. Thanks for sharing.

Ryan, Thank you, I'm happy that you find my humble efforts helpful.

My efforts to learn Fusion 360 is proceeding smoothly. Here's a sample;



Please take note of the taper boiler section. Using Sketch-up to draw that was a real pain in the....Well you know. In Fusion 360 it was two clicks. This is version one, lots of details need to be added. I made some changes to make it printable and sent it to Shapeways so I can make sure it fits the brass boiler centers. It was really nice not having to covert file formats or us another program to fix the drawing. I hope I'm no counting my chickens....as I have not heard from the human checkers yet.

Enjoy
Bob

At first glance I thought it was a flux-capacitor.
