Steam outline experiment

Postby Ozrail » Fri Feb 07, 2014 6:26 am

As much as I love my Flying Scotsman, the problem is you can't put a motor into it.

So here is my next solution, a loosely based Merchant Navy.

I did try to make it 100% accurate, but it wouldn't fit the 16m motor unit.
So the model is way longer (which you can tell by an extra driving wheel in the drawing), and also wider to in size.

Sadly the model is still not ready, as every time I upload it to shapeways, it keeps saying there are thin walls somewhere.
But it doesn't show me where exactly.

If you prepare the files in .stl format, have you got a copy of Netfabb Basic? One of its features is to measure wall thicknesses.

Well the good news is that I finally know what is wrong with my model design.
It's mostly the side panels along the boiler, so I'll have to widen the upper part again.

have you seen the new thin wall checker on shapeways? It's not 100% reliable but is quite good at pointing out areas that need a closer look.

Hi Ozrail

It's great to see you have been busy doing a new loco. When you have done and is up for sale i can see myself getting couple of these and properly doing some double heading ;-)

Well I've ordered one to see how it will turn out.
It's probably going to be too wide (about 7mm) to be realistic, that and I want to see if it fowls the station platforms which is my main worry at the moment.

Sadly the models still use Eishindo wheels, I'm just to use to using them in my models.
I really need to upgrade to Alan's ones sometime.

The prototype has arrived.
And as expected, it's not going to please everyone.
The issue is that to make it work, the loco is sadly a tad (if you can call it that) oversized, which makes it look out of place with the rest of the rollingstock.
Still have no idea what I'm going to do for driving wheels. :(

Anyway I've attached some picture of it connected to a rack of MK1 coaches, to me the loco looks too tall, but sadly I can't do anything about it.

This may be a dumb question, but have you considered making the loco and tender a single rigid unit and mounting the whole thing on a powered chassis?

I suppose it could work, but it would look a little odd especially on curves due to the overhang.
I did try it with Thomas coaches Annie and Clarabel, but it never look right to me.

If by making the shell the right size on the outside means the hole for the power unit is smaller.....then its time to investigate if the power unit can be made smaller!

It might be time to take one to pieces to investigate. :shock:

How much do you need....in which direction, and where from??
