I'm now laid up in bed after a minor op and can't do any modelling, so I've just been having a go at posting them on that Facebook instead. Normally I find social media too much like hard work. I'm only 50, so I think it must be neurological! too many notifications from too many directions. I don't think I will be able to maintain this flurry of activity, and look forward to a return to vertex shifting soon. 1 Link to post Share on other sites More sharing options...

I have to say that I have been looking at this thread and find Blefuscu's work amazing. While home 3d printing is not my area of interest per sey, I am absolutely loving the output. The Deltic and its paint job is fantastic. The PEP derived EMU's are amazing, just think, a classic minories city terminus, either london or merseyside, with 313 or 507/8 and dmus plus a loco hauled parcels, would be immense.

And I love the 3mm dreams! I think I mentioned somewhere my own dream is Hornsey station and depot, 1980, or trying to squeeze as much of it as I can into my loft - if I had a little bit more space I'd be tempted to print them in 3mm too... then i look at the railmaps and overhead photos i think it should be 2mm. Maybe that's how i ended up choosing tt, and modelling a deltic with no wheels 🤔 Whatever scale, it's great to hear other people take on these designs. As the number of designs out there increases, so do the possibilities... combined with the really interesting stuff happening with Templot, I think these are good times. 2 1 Link to post Share on other sites More sharing options...
Blefuscu Posted February 14 Author Share Posted February 14 Some BX1 bogie designs. I seem to have identified four variations... These are just under 3cm long at 1:120, so I haven't gone overboard with rivets and cables. I have also back filled some of the space between components to (hopefully) give them a bit more mechanical strength. Hopefully these will look ok when the empty areas are blacked out and the components are picked out with frame dirt and brake dust. The base I sketched out is mechanically compatible with a Piko one I had to hand. It's not very finished and subject to change, as I am thinking of use an M3 bolt to hold the bogies, or use an existing bogie and change the sides... Obviously, whatever I do here - I will make the free sides available. 2 1 1 Link to post Share on other sites More sharing options...

I noticed that https://www.nbrasslocos.co.uk/ have n gauge top hat bearings too, which I presume would be ok. I made a note about accommodating a recess for a brass bearing on the designs... but there are implications there when scaling the model up or down, so I just have the pinhole marks as a guide for now. 1 Link to post Share on other sites More sharing options...

Blefuscu Posted February 16 Author Share Posted February 16 15 hours ago, TT-Pete said: 3smr have 2 types of bearings Thanks - I'll probably use one of those ultimately. I think there is going to be a bit of tinkering with the design before I fit the bearings. I'm about to try a test print of the bogies... Meanwhile I've added the .stls to the Class 313 on cults3d and have also listed them separately as a free design in case anybody wants to have a proper look at them. https://cults3d.com/en/3d-model/game/tt120-scale-bx1-bogies-for-class-313-emu 2 Link to post Share on other sites More sharing options...

Blefuscu Posted February 24 Author Share Posted February 24 ...and the ST. The front bogie shown is the 210mm Halling H0m https://shop.ferro-train.com/hallingShop/Article/ANT-ALX-210-H0M I'm not intending to put a powered bogie on the second trailer, I was just offering it up for a look see. You can find the 3D models of the Halling bogies here (they are in STEP format but easy to convert to .stl using freeCAD) https://www.halling.at/Drehgestellantriebe-.html 5 Link to post Share on other sites More sharing options...
Blefuscu Posted March 1 Author Share Posted March 1 Printed, they look something like this... This was the second attempt as I'd used the wrong abs-like settings. "V2" feels very different to "+" too, they are quite different resins. I increased the supports 2nd run too.... Sometimes this printing game feels like witchcraft. The bogies were damaged in the first print run... where two chassis adhered to the bed!! They are salvageable, but I want to add a recess for my bearings (Peco n gauge ones) which have arrived. Don't have a bogie yet. I'm still considering the Halling 21mm coreless one, as above... but need to sell some stl files first! 3 4 Link to post Share on other sites More sharing options...
natterjack Posted March 1 Share Posted March 1 To pick your brains, what sort of 3D print material would give the flexibility of modern RTR bogies which can be eased apart for wheel insertion etc. & which seem to be some sort of polypropylene?

Funny you should ask, but I just did a test fitting of Piko ICE3 wheels. These bogies are printed in 'Anycubic ABS-like V2'. This was my first go with ABS V2, but it's very popular with in the Templot forum for printing chairs. This wheelset popped in quite easily - but the resin hasn't been fully cure yet. It might be that it becomes too rigid and cracks once it's cured. However, it's predecessor, the 'ABS-like +' , remained slightly pliable even after curing so I'm hopeful that it will be ok. I tried to fit a mueller 8.3mm tillig/bttb wheelset, but they have slightly longer pins. I'll need to re-version the bogie for those wheels if I use them and I'm also going to add holes for Peco NR-91 bearing cups anyway... these bogies are designed for the bin ultimately*, so that's no loss, but it's a promising start. (*There's also a weird print defect on the back of the bogies where it skews off at 45 degrees before finishing off the print.) 2 1 3 Link to post Share on other sites More sharing options...
Blefuscu Posted March 3 Author Share Posted March 3 I've just cured the chassis, and it's still quite flexible at 2mm section.. The thicker bits seem very strong. PS I've been curing them lashed to a wooden splint to prevent them turning into bananas, and that worked. 1 Link to post Share on other sites More sharing options...
