Elegoo Mars as well (first edition not a Mars 2 or Pro or anything). It doesn't happen all the time, it maybe not be linked to the angle, perhaps a part of my hardware is wearing out and needs replacing. I'm currently out of resin so I need to get done more and work out where the problem is.

I've found some strange striations when I put a 20 degree or thereabouts angle on the object I've done a few things at 10 degrees or so which seem to be much better. A very slight angle in another dimension of less than 10 degrees doesn't seem to go amiss with my prints. If it doesn't work you can always go back to your tried and tested method.

I usually give a slight angle to my prints in 2 dimensions as it takes some strain off the FEP film. As an example of what I mean, instead of pulling off the entire square footprint of a wagon for each bottom layer, it would only pull off a fraction of that at a time, which takes less force to remove and therefore lowers the risk of tearing/deforming the film. It can also help the layers stick together-rather than the bottom of our wagon being flat layers that could peel apart, it is made of many more layers at an angle. That being said you've been very successful in your prints so far, and I'm sure you're more knowledgeable than me. Looking forward to seeing what comes next!

Better pony truck design. I think I'll test print this tomorrow, although with some resin I don't quite know how to use yet so it may come out awfully! I think for now I'll leave off the cylinders, I can always try and add some later. Looking forward to finally having a 00n3 loco!

Thanks for the numbers David and the suggestion Galteemore. I'd rather keep this loco skirts-free if possible, I've done so many trams in 009 it'd be nice to do a loco without covers. I may try and put some cylinders around the cuboid protruding from behind the pony truck (the original chassis buffer beam), but I'm a little worried about these obstructing the movement of the pony truck. The Barclay 4-6-0s on which this loco is based has 14" diameter cylinders which would be 2'4" for two, a very tight squeeze but potentially do-able? I'll see how I get on with adding cylinders.

I've been suggested a way to avoid pfaffing about with making cylinders and rods. The boiler is already higher than on the prototype so there is a bit more space to fit in inside cylinders driving the 2nd axle. A quick photoshop showed me this is vaguely plausible: It could even have the motion on the first axle, a bit like Dolgoch on the Tallylyn Railway. The size of the outside framed bogie would allow access to the inside cylinders. It could be an experimental design which didn't really catch on. As it's a freelance loco already I'm happy enough with this reasoning and it's always nice to have a little bit of 'backstory' to a freelance- if a real loco can have a history why can't it! Happy to hear any comments or criticisms.

I couldn't make the chimney thicker without making it look really weird so I've added 1mm to it and the dome's height and they look much better to me now. I've also added a few more details and drawn up the front pony truck, taking inspiration from the Donegal class 5 and IoM Beyer Peacocks. It doesn't leave much room for cylinders but I'm sure I'll think of some way to add them.

Thanks! Unfortunately I can't make the dome any fatter without it overflowing onto the tanks, but I'll thicken the chimney.

Looks good! You're moving at a much faster pace than I!

Did a bit of work on her this morning. As the boiler is pitched higher, and I'm trying to keep it with the same loading gauge as the 4-6-0s, the chimney and dome look a bit small. I'm sure it'll look fine when painted and moving around on the layout.

Thanks for this. She's based on the 4-6-0 drawings. I did have a look at a bigger TT chassis, but I think that they'd come with their own compromises, and so I think the next step in my 3ft modelling will be to make my own chassis. I'm planning to do a Donegal class 1 2-4-0. Perhaps in the future I'll do a half-cab no.4, as Dr Alan Gee has, as it's quite a pretty engine. So are Aberfoyle and Richmond, you're quite right! So many ideas... Thanks

This is how the project is ending up looking; it's taking form nicely: Going for a 2-6-0 wheel arrangement, as I've been able to regauge a 00 wheelset I had lying around. They're fairly big wheels and I may do outside axleboxes for interest, like the Isle of Man Beyer Peacocks. I'll leave the bufferbeams bare until I choose a coupling style, Branchlines' chopper couplings do appeal for that look of realism. Thanks for reading!

Thanks airfixfan, that lends credibility to that idea!

Over the Christmas break I hope to make a custom chassis for a Donegal class 1 2-4-0, which seems like an easy enough one to start with and something I'd like to have anyway. The engine to fit the Triang TT chassis I am more than happy to freelance, it will be a nice first engine I reckon and won't be the best 00n3 model ever, although I'm not trying to make it that. Looking forward to working on it more soon!

Thanks for the suggestion, I did consider it but I find the dome rather offensive. Did it have a different one at some point? It may have the same problem of the motor being too tall and sticking out of the front of the cab, I'll have to try it out if I can find drawings. Thanks for this suggestion too, and that would make up quite a smart loco. I'll see what I can do! I think it's here : https://transportsofdelight.smugmug.com/RAILWAYS/IRISH-RAILWAYS/LONDONDERRY-LOUGH-SWILLY-RAILWAY/i-Z9sr578/A

A bit of bored 3d modelling of a L&LSR/L&BER 4-6-0 gives me this, with the TT chassis dropped in roughly in red: As the motor is protruding from the front of the cab I think I'll extend the bunker back and move the chassis backwards, which will also give the space (I hope) for a shorter wheelbase bogie in front of the TT bufferbeam. If not, I could make a 2-6-0. Thanks for reading!

That rear wheel looks much more like it for the BCDR tanks

I'm hoping mine is okay. It seems to be relatively okay so far, and as my layout is flat I don't have to worry about the hill problems. A few times it hasn't started moving straight away, but after a second or so I hear a spark or something go 'click' and it moves. I have a similar problem with my 009 L&B Manning Wardle and I'm not sure if it's fixable but I can live with it.

That is a limited edition one, so I'm probably going to sell it for a less valuable one to make into a VS but that's absolutely on the projects list.

You have the Hornby version. I have an Oxford, which has an inferior chassis design however at £48 I thought it was a fair price. The Radial body will be recycled into the freelance 4-4-0 posted above I also have Hornby's no.3125 but I like it too much to cut up and I model Southern too anyway!

The chassis has arrived and is de-cylindered. I think this may have had an affect on the quartering. The wheels seem to slip out of sync slightly after a bit of running. I'm not entirely sure however if this came from take off the cylinders as I'm unsure how that would have that effect, but oh well. The trailing wheels are a tad small for a BCDR tank but I'm happy to overlook this. The radial body is now in bits and awaiting modifications to both the superstructure and to fit the chassis. Thanks for reading!

Those are nice engines too. I really like some of the GNRI tank engines, perhaps once I've cleared my mile-long narrow gauge and BCDR to-do list one will form on my workbench. Was there ever a 'handing over' of passenger or goods trains between the BCDR and the GNRi? For example a train to Bangor from Armagh or vice versa. That would make a nice tie between any GNRi and BCDR stock I make.

I wonder if it was inspired by success of the SLNCR locos...

Fixed the tanks and running plate on the design: While I was at it, I modified the cab to look more like a BCDR style cab, and I'll have a go at a more SLNCR one at some point too: I quite like the 4-4-0 Galteemore mentioned, but the a freelance BCDR one would mean I can run it with the same trains as my 0-4-2 and the proper 4-4-2! That seems the most sensible thing to do. Open to more comments/suggestions!

Just found this thread and it's been very interesting to read. Most admirable modelling indeed!
