Westcorkrailway Posted February 23 Posted February 23 Saw these on FB, maybe the poster is active on here, but couldn’t help but share these 3rd printed models of GSR 299 7
Colonel Posted February 24 Posted February 24 Remarkable what the alchemists are getting up to these days. If the chassis is separate, or can be cut out, suspect there is a HighLevel motor gearbox that could fit. Certainly looks like it would be possible in 7mm scale: Slaters do this style of wheel and they come on 1/8" axles, ideal for aforementioned gearbox 2 1
Horsetan Posted February 24 Posted February 24 Manning Wardle type driving wheels are available from Alan Gibson Workshop, as are universal coupling rods, so "all it needs" is a chassis to match if the wheelbase is known... 1
Westcorkrailway Posted February 24 Author Posted February 24 In my mind I would be happy to have this static, sitting in a siding somewhere 1

Westcorkrailway Posted February 24 Author Posted February 24 I don’t think I have ever seen a photo of it running, granted it did move, and was largely being repaired for fenit harbour work at some stage in the 50s, but in CIE times it was seems to always be a static exhibit.

Lurking in a backyard shed in west Dublin? I can't imagine that there was ever a comprehensive set of drawings for it! 1

I think it shunted the west-side quay sidings friom Albert Quay at one time. Whether it ever went "out" on scheduled services there I would think exceptionally unlikely. 299 would be easy to paint anyway; just drop it in a vat of very dark grey paint! Or, actually - serious point here; I know nothing of 3D printing but sionce that thing is bright green, does that mean that someone doing this can print something in a colour of their choice? If so, if a very dark grey plastic was used, and it wasn't translucent, all the modeller would have to do is paint the chassis wheels grey to match and away ye go.

There are fairly set colours when it comes to 3D printing, you can’t, for instance, Just set the printer to a colour. You get a roll of Meltable plastic, usually either a bright colour to help during testing. I have used 3d printing filament that is similar to GSR grey, but I’d deffo reccomend painting it to improve the rough finish of some 3D printing! 37 minutes ago, Horsetan said: I'm not sure there were any drawings.

As somone pointed out recently, I wonder did sambo have drawings at all, considering its construction seems to be of mostly spare bits and sheet metal

I am unfamiliar with the technology, but appreciate its continually improving results. As for Sambo, yes, bits and pieces, like "Pat" in Cork. Almost certainly no drawings for either.

I made this model and printed it not too long ago, I now have a motorised chassis on the way in the post to hopefully mobilise No. 299. I’ll post the progress int his forum soon.

I might have a side profile drawing of the loco in my LOCOS OF THE GSWR book. I’ll have a look 4

No front or birds eye view profiles unfortunately, just this view. 1
