I think he's still able to get his ingredients. Alan I believe Gavin will do 7mm prints. His home resin prints are superior to Shapeways and very significantly cheaper. When I re-order, I might take the loco and tender chassis from Shapeways in WSF, but ask Gavin to print the bodies. This is one supplied to the West Norfolk Railway, so may be a mix of Cambrian and Furness details, but Gavin does both. This is his home print (in 4mm). Very good.

To short for an LMS Standard 3F (a particularly large 0-6-0T) but too long for most others! Closest I've got is the GWR 5600 0-6-2T. Correct wheel size, but 5" out on the w/b and I wonder if that makes it better or worse than the Old Hornby Jinty? Of course, I realise that don't know the wheel diameter of the Hornby chassis. 5600 4’7 ½” 7’3” + 8’ = 15'3" L Class 4’7 ½” 7’6” + 8’2" = 15'8" 1 Link to comment Share on other sites More sharing options...

I don't know if things have improved recently, but the centre wheel on the Hornby 0-6-0t has a vestigial flange only and I think it is either a touch smaller or set higher. As your daughter might say, not a good look. 19mm scales out at 4'9" the diameter on an LMS 3F was 4'7". Additionally, for those thinking of tinkering with a second hand example, the drive can be either to the front axle or the middle one.

Alan The example I measured is moderately recent (2010/2011) - Made in China, centre axle drive, all wheels flanged and of the same diameter. Going further back there were various dodges; the Triang version simply used the wheel centres without the flanged steel tyres on the centre axle - essentially a jack-shaft driven 0-4-0! 1 1 Link to comment Share on other sites More sharing options...

Nearholmer Posted May 4, 2020 Share Posted May 4, 2020 (edited) Pedantic voice (no change there then): an A-1-A has the two outer axles separately driven. TBH I have no idea what the notation would be under the UIC system if the centre axle had actual carrying wheels; there may not be a notation for it.

RMweb Premium Compound2632 Posted May 4, 2020 RMweb Premium Share Posted May 4, 2020 There's that weird Belgian locomotive that breaks the system. A six-coupled tank engine with carrying wheels ahead of the trailing coupled axle. Hey! that was easy... Perhaps the old-fashioned way perpetuated by HM Inspectors has merit: four-coupled with tender = 2-4-0 unless otherwise qualified bogie four-coupled with tender = 4-4-0 etc. 3 Link to comment Share on other sites More sharing options...

Have you seen the horror of the old Lima n gauge B-B chassis, thats actually the standard 4w motor bogie with a pony truck each end and fake bogie siderames. Lima were responsible for quite a few crimes against wheel arrangement notation 3 Link to comment Share on other sites More sharing options...
Nearholmer Posted May 4, 2020 Share Posted May 4, 2020 (edited) The four-wheel motor block in the middle plus two pony trucks dodge has a very long and respectable heritage in tinplate trains, both for “bogie” electric locos (which could well be clockwork) and for steam locos: see the picture of the Flatiron that I posted before. Some didn’t even have the pony trucks, just the dummy side-frames. I think the Hornby 1920s Met electric is like that, although above the running plate it’s not a bad representation of the real thing.

Knuckles Posted May 5, 2020 Share Posted May 5, 2020 (edited) Thanks for the shout out. Will just clarify I still have several liters of resin and around 13 of alcohol so good to do 3D printing still. The chassis I'll be making Shapeways only as they turn out better but the body kits n details still fine to print here. Have covered most the Cambrian and Furness variants for the loco's in question. As to 7mm prints on the Photon, due to small bed the bodies likely would have to be chopped in half but could have a look to see what's viable if anyone is interested here. Tenders will fit anyway. So far I chopped up one of my Pacific bodyshells and printed it in two halves. Join line wasn't bad but does need a dab of filler as expected.
