650 Class Preview

[Mayner]

Some photos of the build of the study models for the ex-MGWR 2-4-0, this is basically to see if the model is buildable.

 

The basic assembly of the platework is complete, the boiler fittings are just plonked on for general effect, some modifications are needed before the kit is released.

 

The model is assembled in OO with Romford wheels resulting in the wheels being inside the boiler/firebox shell.

 

There was a mix up at the engravers the locos ended up in nickel silver, the tenders brass.

 

650 Class late MGWR early GSR condition, superheater round top boiler, round canopy cab, tender coal rails.

 

These cabs were used as a replacement for the "Flyaway" cabs on the 2-4-0s and some 0-6-0 but were phased out during the 1930s, they were low (a source of staff head injuries) and gave poor protection from the weather.

 

650 Class late GSR condition superheated round top boiler, Inchacore cab with round spectacle plates.

 

The GSR replaced the canopy and remaining "Flyaway" cabs with what was basically a standard Inchacore pattern and replaced the cast iron chimneys with a standard Inchacore "built up" variety.

 

 

Close up of the loco showing cab and smokebox riveting.

 

At this stage its difficult to predict the probable cost or release date, but I would expect Summer/Autumn 2014.

2014 maybe John?

 

She looks sweet, when would the late condition version have been withdrawn?

looking forward to seeing the finished product...shes a little beauty!

[RedRich]

That is quality John, it's definitely going to be a winner.

 

Rich,

Most lasted to the late 50s with 6 surviving into the early 60s.

 

They seem to have worked passenger and mail trains on the Sligo and Mayo lines, Dublin-Bray suburban trains (both routes) and Wexford Mail trains until replaced by diesel railcars/locomotives.

Excellent, I fancy a late one so, I take it these will be built for both OO gauge and 21mm gauge?

[jhb171achill]

I would be interested in a later one. Absolutely stunning kit. Would there be an option to buy a fully assembled one? Neither my modelling skills nor eyesight would do justice to a model like that!

[Mayner]

The loco can be built in OO or 21mm assembling a rigid OO chassis is fairly simple and she should be fit to go round 2' radius curves.

 

I will certainly look at doing a small batch in OO Gauge rtr.

Thanks John, I'll be interested in one.

me too

I've a notion that one of these was painted black instead of grey in very late days. I'll investigate which one (or if I'm even right on that one!).

[Horsetan]

It must be wonderful to understand how to use CAD. I have AutoCAD 2005 here, but I cannot understand how it is supposed to work or how measurements are reflected.

".....I've a notion that one of these was painted black instead of grey in very late days. I'll investigate which one (or if I'm even right on that one!)....."

 

I investigated the above, which I posted the other day - on perusal, I'm probably wrong, as the picture is strong in contrast. This often made grey locos look black, especially when combined with the sheen of oily rags polishing! I'd stick with grey for accuracy.

[Mayner]

Its hard to believe that its over two years since I started this thread and not so hard to believe I still haven't finished the locos:rolleyes:

 

I am updating the artwork to include inside non-working valve gear, but haven't had a chance to look at the drawings since July.

 

 

The gear is based on the Beyer Peacock GA of the earlier D Class 2-4-0 although the K Class cylinders are further forward of the leading axle and motion bracket than the earlier locos.

 

I will have to have a close look at the valve gear on my large scale Mogul or a full size loco to position the eccentric rods even half right.

 

I have used the same CAD programme for over 10 years and I am still learning and discovering new short cuts and features

Mayner, were you at one stage considering doing a small production run of these, made up? Or did I get my wires crossed somewhere?

I thought it was going to be a kit only?

[Mayner]

I thought it was going to be a kit only?

 

The demand for Irish kits of this nature is very limited, the next stage is to establish if there is enough demand to release the loco as a complete kit or simply the etched parts with the builder sourcing wheels, castings etc.

 

It should be feasible to build a few as rtr models, the main problem is finding the time to complete other unfinished projects.

[Horsetan]

Wheels may not be a problem for an etch-only pack, but castings will be.

[jhb171achill]

I want one too; I'm there.

 

Despite 04:20, just in from U2 gig and many very late pints.

 

Life is good.....

Was wondering why you had several late posts. It's time for Zzzzs ...., and I'm on Pacific right now

[jhb171achill]

Just finished "ZZZ-ing" and its almost 2pm.....
