enginear joe Posted August 1, 2016 Share Posted August 1, 2016 Very interesting design. I haven't seen any like that over here. I usually have to pull the springs to swap out wheelsets. Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted August 1, 2016 Author Share Posted August 1, 2016 Thanks. The thing is - I have no experience with this, so I don't know if it's actually a good design. I go with my gut feeling and try to make a model that is easy to deal with - even for an inexperienced modeler. That means I do take the time to search for alternative and maybe simpler solutions to problems. Jens Edit: I'm told that the German manufacturer MBW is using the same scheme - albeit with tighter locking on the bearings - so it would seem I'm on the right path. Makes me think maybe I should tighten the locks in the cutouts as it's easier to remove material than to add it. Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted August 4, 2016 Author Share Posted August 4, 2016 Still having some issues with modeling the 3D solids. Looks like I may have run into the limitation of the CAD software, so I need to find a way to work around it. The good news is that preliminary testing (still only in CAD, mind you) shows that the trucks pivot unrestricted when put in place under the cars, so the minimum curve radius that the cars will handle should be very small.

SteamPower4ever Posted August 5, 2016 Author Share Posted August 5, 2016 Still need tweaking, but I tried uploading a test model this evening, and I'm very close to my target price Quote Link to comment Share on other sites More sharing options...
enginear joe Posted August 5, 2016 Share Posted August 5, 2016 Are you ready to announce that price to the public? Just wondering how much they will be. I will keep watching. Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted August 5, 2016 Author Share Posted August 5, 2016 Not quite ready, but it's comparable to Accucraft trucks. Jens Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted August 7, 2016 Author Share Posted August 7, 2016 Alright, here goes nothing I've ordered a test print of one truck. Looking forward to see what I actually get in the mail ... The current price for the print of one truck is 42,57 Euro or 47,31 USD at today's exchange rate. Subject to change and not including shipping.

SteamPower4ever Posted August 17, 2016 Author Share Posted August 17, 2016 Here's the truck with bearings and NWSL wheels mounted and sitting on Märklin code 200 track. I haven't made up my mind yet, but look at the springs and it rolls like a champ. Let's see when it gets a coat of paint and braces at the forks mounted ...

enginear joe Posted August 17, 2016 Share Posted August 17, 2016 I'm in! Has a tuff look to it. Maybe you'd make many extras for people to help rid the shortie trucks that are out there? Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted August 17, 2016 Author Share Posted August 17, 2016 It still needs tweaking, but when I'm happy with it, I'll make it available on Shapeways, so anyone can order as many as they like. My plan is to also release the CAD drawings as open source, so anyone can make modifications or print the trucks elsewhere if they find a cheaper or better service.

SteamPower4ever Posted November 16, 2016 Author Share Posted November 16, 2016 I've made some minor modifications to the truck and ordered a mk2 print from Shapeways - also to try a different surface, what they call "strong and flexible polished". The polishing is actually some sort of media blasting, so intricate details may be lost. Good news and bad news. I still haven't nailed the brackets below the axle boxes. The studs have broken off - probably in the polishing process, so I need to rethink again and there'll be a mk3 version. The 'polished' surface is much nicer though. Not like a mirror, but much smoother than the ordinary "strong and flexible" material. Here's a truck fresh from the production line: And here it is with the NWSL wheels and bearings mounted. A great thing is that I got the mounting right first time. The bearings clip right in with a gentle squeeze with pliers and they stay in place nice and tight.

enginear joe Posted January 22, 2017 Share Posted January 22, 2017 I really forgot about this. Are the trucks available yet? Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 22, 2017 Share Posted January 22, 2017 Those are some beautiful trucks, nice work, no, fantastic work, I like it. Bob. Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted January 22, 2017 Author Share Posted January 22, 2017 The trucks are still incomplete. I need to figure out how to design the lower axle box braces. However, the entire project is on hold for the time being. Jens Quote Link to comment Share on other sites More sharing options...
du-bousquetaire Posted March 6, 2017 Share Posted March 6, 2017 I hadn't been following this as I had an operation, this is a really fascinating evolution although I am interested more in the standard single level Budd design. Congratulations on the design process. A word of caution about wheel standards though, I wanted to go finescale in gauge one, but stayed within the Gauge 1Model Railway Association standards, so that I could hold get togethers on my track. Otherwise I would have had a "captive layout" and no friends could come and run. This is most important for live steamers. Some French friends who are developing a French (NORD design) truck from laser cut brass parts and castings had the very same problem with wheels thicker than scale wheels. I will be holding a steam up on the 28th of may of this year for those in Europe. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted November 3, 2017 Share Posted November 3, 2017 Jens, I am thinking about stretching some Great trains Superliners and remembered in a previous post that you said that you might allow the use of the your 3d files for the Superliner trucks and am wondering if that offer is still good? I don't expect to use it for free, and I am willing to pay for it. Have you set it up with Shapeways for sale? I don't know exactly how that works, but either way, I am very interested. I might be buying a 3d printer as your models look fantastic. Thanks, Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted November 3, 2017 Share Posted November 3, 2017 After wanting to use your beautiful trucks, I found out that the Superliner II uses different trucks than your earlier ones, so it looks like I will have to design my own, but thanks Jens.

Fonzie Posted April 1, 2021 Share Posted April 1, 2021 Boy this is a great project as especially like the idea of extruded aluminum bodies! Wonder if Jens ever went ahead with this project? Quote Link to comment Share on other sites More sharing options...
