OK so, here's a few photos of the smokebox/boiler barrel and firebox of the Jamieson V2. Note that all you get is the bare outline - no boiler bands, washout plugs, mudhole doors or rivets:

Thanks. Helpful pictures. Funny sound of whirring cogs here as I think about possibilities.

Tell you what Ivan, that Jamieson part must be a good twenty years older than the Bachmann tooling and it captures the shape so much better.

In-house design and manufacture by people who understood what it was supposed to look like, as opposed to literally a game of Chinese whispers with technicians and operatives on the far side of the planet who had never seen the real thing and were probably not very interested in anything beyond the production of an item that would sell?
By the way, for those who have asked, yes you'll be able to have V-front cabs if you want them, when I've managed to cast some. I glad it is a popular move.
Here it is, almost ready for mould making. I shall try to remember to mark the underside of the floor for drilling sockets for crew seats and reversing stands transferred from a Hornby super detail cab, before I make the mould, which won't happen until my supplier manages to re-stock reasonable sizes of liquid silicone rubber. As the method I plan to use will accommodate the change, I've enlarged the spectacles which previously narrowed down to a slit "inboard" so that they now have the correct five sides. Larger still might have been better, but the thickness of the plastic and the desire to shutter them on the the inner face for casting purposes created certain limits. All that window and rear edge shuttering is only 5 thou by the way so will produce fairly thin flash of the final castings, easy enough to break/trim away. The presence of the shuttering does howver make it easy in principle to produce a tidy two-piece mould in a predictable and reliable way. The cab will firstly be bonded "nose up" to the floor of a moulding box, those shuttered rear edges stuck FIRMLY down, my lesson having been learned from the buoyant GC bogie wagon debacle! A first pour of rubber to completely immerse the cab and create the whole outer mould will be allowed to set. I can then turn the whole thing over, release the base from the rear edges of the shuttering, and then (in the moulding box again) apply release agent to the exposed rubber face then pour a second half to the mould, procducing the cab core and an ovelapping rear closure layer that ensures accurate alignment of the two parts of the mould. I've arranged everything inside the cab, inside the firebox, and under the cab to suit the way the mould pieces will fill and subsequently pull apart. The slot in the bottom of the backhead for fitting to the rear lug on a Hornby chassis is still there, although I may not be able to cast it to full depth without soon losing from the mould the "tongue" of rubber that creates the slot. I may have to cast just a shallow slot -users can deepen it by linked drillings if desired.
The pump clip design rather took my eye last night by the way.........

Why don't I just send you the entire Jameson kit, and you can then pick and choose the parts that might be suitable as resin masters? There's a pre-shaped footplate in there as well...

Excellent!By the way, for those who have asked, yes you'll be able to have V-front cabs if you want them, when I've managed to cast some. I glad it is a popular move.
I am sensing the emergence of an almost full V2 resin kit appearing...which would suit me fine as it would solve a lot of the problems of the Bachmann V2 by simply dispensing with the bodyshell in its entirety.Horsetan wrote:Graeme:Atlantic 3279 wrote:Thanks.

To get an accurate Bachmann V2, buy a new one, then throw the body away...S.A.C.

It's a shame, we have a very smooth running mechanism and decent enough tender but have to do so much cutting and shutting to get an accurate V2, but there you go.

...which, with apologies to Toyota, is why Hybrid Synergy Drive is the answer.

Please explain, Horsetan?
If I ain't here, I'm in Bilston, scoffing decent chips at last!!!!
Re: Atlantic's workbench, inc. RTRconversions - now some etc
Looking good there, can't wait to see how the castings turn out. Although I'm not sure about the two tone blue-grey colours - very attractive though!

Yes, but someone had to solder it all together first......!S.A.C. Martin wrote:Tell you what Ivan, that Jamieson part must be a good twenty years older than the Bachmann tooling and it captures the shape so much better.
Simply this: the mating of parts from different sources which drives the "look" of the model you want to capture. Hence Hybrid Synergy Drive.Blink Bonny wrote:Eh?Horsetan wrote:...which, with apologies to Toyota, is why Hybrid Synergy Drive is the answer.

It's great to get all your ducks in a row.

Re: Atlantic's workbench, inc. RTRconversions - now some etc
Meanwhile we wait to see whether Graeme wants to make use of the kit. It must be at least 40 years old now, possibly even older.
