Hi Folks SO it's crazy Ken form Cape Town Southern end of Africa
My brother and I attended a steam running day couple weekends ago and we chatting over a ice cold beverage. As much as we love our 5' engines and that we are both build 2 other engines each, we really need to get a 7 1/4 that can pull more people as ours can only handle 2-3.
So we both like the look of the Simplex and the real simplicity of the build would make it relatively easy and quick to build. So I have the plans and the Martin Evans book and I am busy drawing the model to 7 1/4 scale which is not to difficult. But now we have started discussing the 0-6-2 option and what would the benefits of the trailing bogie be. I presume the boiler would be longer and be more stable on the track.
So any comments, suggestions, pics etc would be welcome
So first question I have is on 5' the side frames are 1/8 or 3mm And if we multiply y 1.5 or 1.45 as I have seen id the recommended factor we get to 4.5 mm. Now here is RSA (Republic of South Africa) we work with metric size material. So is 4 to thin or 5 to thick

So a update on progress. One of our local club members at out club in in Cape Town put me onto the 7 1/4 Bridget which was serialized in ME 136 and 137 Lucky for me I have most of the ME from 1960 to 2000 and lucky for me they where top of the storage box.
I have moved the rear wheels back out of the way of the ash pan on mine. Bigger capacity and the grate just drops out! As she is Freelance you can do all sorts to her!
David and Lily. I once spent 3 days in Cape Town... 1968 Christmas.
Builder of far too many projects, but I love them all. The more Locomotives you have building, the more solutions to other Projects Problems get Solved. Reworking Simplex into a Fowler Complex. Making a Jinty more to scale. And going up a size in the shape of a Jessie.

So David did you build a 0-6-0 or a 0-6-2. Having easy assess for the ash pan is important. One option we are looking at though is to be able to have a gas fire option. We want to design a engine that has various option avialable . Begin able to do 0-6-0 or 0-6-4
Gas or coal
Side water tanks or water in rider coach
Injectors or axlepump or hand pump in side tanks or handpump in rider coach
So drawings are coming along nicely but spend a lot time thing about the 0-6-2 arrangement. I am mainly doing it because I like the look of the extra trailing wheels But what advantages to i get for it. I can extend the boiler But does this extra set of wheels make the riding of the engine better.
The 0-6-2 version was in an article by John Jones in ME 9th May 1997. The idea was to enable the size of the rear bunker to be increased for extra water capacity and to make the loco more commfortable to drive.
My own reasons for designing an 0-6-2 version was mainly to extend the boiler to give more grate area.
Morning World So was up early this morning. And spend some more time working on the drawings. I understand why most model builders have not bothered converting old drawings to metric. All starts well and then half way you start going back to the being more and more as you find parts not working out. And then up sizing the parts to 7 1/4 makes it one ^$*@%^@&*8 But lots of fun and should be worth while in the end. Anyway another day or so and the Valve gear should be finished
