Scratchbuilt 2-6-4 tank loco

[ge_rik]

It's a nice little block, but sadly VERY small when compared with 15mm/ft irish NG. I've never yet had time to prepare a datasheet, but wheelbase is 56+58mm and wheels are approx 37mm diameter over tread.

Thanks that's really helpful. The block may not be right for one of the larger Irish tanks but methinks it would look OK for a 15mm model of Southwold's 0-6-2 Wenhaston.

Wenhaston had a wheelbase of 3'7" (ie 53.75mm) and 3'8" (ie 55mm) and wheel diameters of 2'6" (ie 37.5mm) - which I think I could get away with. Although the wheel centres would be closer in 16mm scale (57.33 and 58.67) the wheels would be a bit too small (ie should be 40mm in 16mm scale). I think smaller wheels are more obvious than having the wheel centres slightly out, though. Only drawback is I'd have to construct the @*##$ valve gear!

Have to admit I keep on thinking down the same lines, though if I ever put one into production it would be a rebody of one of the Piko locos to save builders the valvegear grief.

What keeps killing it (most recently on Sunday, when I was stuck at home missing the G scale show) is that when I get out the Southwold plans, I'm suddenly reminded how small all their stock was. Genuine UK mainland 3' gauge maybe, but the loading gauge is more like festiniog dimensions.

In 15mm, Wenhaston comes out a mere 90mm wide and 133mm tall, though it is about 270mm over headstocks. Proportions to match otto and the toytrain range rather than stainz and starter set coaches . In 16mm it'd be a fraction bigger, but still on the small side vs most G stock. Which is why I keep shying away from both No4 and the Sharpies. The Harz lines used to have a couple of pretty series of T3-esque 0-6-0T (last survivor 99 5811) and a pair of 0-6-2T (99 5631/2), but they have the same problem - model them in true scale (1/22.5 in their case) and the things are tiny.

Any chance you could let me know the wheel dia and spacings for the motor block - or point me to a data sheet somewhere online? I'd like to narrow down a couple of possible prototypes.

Thanks
Rik
PS - not been able to find a photo of an original but here's a model of what I had in mind

That's a nice long, low loco.
The PIKO block has 36.5mm dia wheels and 57mm spacings for the axles.

The locomotive is one hell of a beast, love the photo of it head on. Like Rik I've always fancied an Irish 2-6-4 which I'm assuming will probably be about the same size. I've been collecting bits for it for about a year but think I'll use a Bachmann Big Hauler chassis as the diameter of the wheels are rather large on the prototype. I've never considered sound but after seeing your build I'd like to try that too

Thank you and everyone else who likes it and commented!

As to using a Bachmann big hauler - yes it would be better. Just for comparison, here's a pic of two of my models. Both the prototypes have the same basis - wheels , boiler etc, just one was built as a tank and one as a tender but with common parts. My tender model is on a Bachamnn chassis and the bigger wheels look better than the PIKO ones under the tank. Both models use the same pipe for the boiler.

Rik,
yes making cylinders and valve gear is a pain - that's why I chose the prototype I did!.
But that photo is almost my Lexie loco if you added cylinders!

I have to be honest Gregh your model looks better than the prototype . I do like your 0-6-0 tender engine thoughts have being going on to build one myself bsaed on a GWR deans Goods as to the piko 0-6-0 chassis I think its avery useful chassis for scratchbuilding etc I have been toyiing with one paticular loco an ex ww! ROD narrow gauge hunslet 4-6-0 tank engine I have a full set of drawings and I belive some were converted to meter gauge after the war . Nice model !!

 

[g-bits]

Think I agree with you there - the wheel spacing on the prototype is looks distinctly unbalanced compared to Greg's, even if it wasn't in reality.

The ROD 4-6-0T's are interesting locos - built for 60cm / 2ft / 2ft6, with some later converted to 2'6-1/2", 3ft and metre (think at least one of the conversions also changed wheel arrangement - there might have been drawings in continental modeller a while back).
