A question for the Fusion 360 experts

Andy,

Being fascinated by the NER I am fortunate there is a good source of published materials and truth be told they didn't have many variations of wagons or brake vans. OK the running gear got update as did the brake gear, but the basic wagons tend to not change very much. I suspect there are more variations of coaching stock than of freight stock.

Source 1. The Brake Vans etc come from a book Northen Eastern Railway Brake Vans by Ian Sadler. It covers most of the vans built by the NER, it's only problem is a lack of consistent scale. I'm pretty sure they were all drawn at 7mm but then they have been reduced or expanded to fit into an A4 book, luckily there's normally scale printed with each diagram so with a bit of faffing about you can it figure out.

Source 2. Peter Tatlows LNER Wagons volume 2 which covers the Hull & Barnsley and NER wagons. Same scaling problems, less detailed diagrams but it has has many photos to work help details etc.

Source 3. The NER Record. Both Rob and myself are members of the North Eastern Railway Association. They publish a quarterly magazine which often has diagrams of locos, coaching and freight stock. These are all available on-line so you can extract the diagrams. I have an almost complete set of the publish wagon diagrams. They tend to be drawn at either 7mm or 4mm scale. Ian Sadler contributed many along with a guy Richard Lacey.

Source 4. The NERA archive. They have copies or originals of over 7,500 drawings, not just rolling stock but pretty much anything to do with the NER. These are available as downloads from the archivist. I have attached one as an example.

I guess with a bit of digging you would probably find similar for your North Staffs Railway, perhaps under the guise of the LMS. Rob/Paul anything to add?

Andy,

It sounds like Paul is you man.

Well the Dia 60 Luggage experiment is over. It started as an excersie in "how to to a tumblehome" and went on to splitting so it would fit on a Photon Mono build plate.
I have no intention of printing it so wont be taking it forward from its current state:

As a single body:



And split with alignment pegs to aid a build:



My next experiment is to import a drawing as a canvas and scale it. I know Paul and Rob do this quite often but I haven't a clue how to do it. It to dig through the Fusion help screens.

 

I think I have cracked the scaling game:

Import a drawing with know dimensions.
In my case the dims are ft/in, 18ft 8 in, so convert to O gauge mm (i.e. 18.66 x 7 = 130.62)

Use the image calibrate function to define the start and end point of the know dimension and specify it in mills.
Move the image so a bottom corner is sat on the origin point.

Well guys, right or wrong?

 

Eh, what a laugh. I chose a drawing from Peter Tatlows LNER wagons of a C8 Sleeper Wagon.
Used the body length to calibrate the drawing, Sketch the Solebar standard 1ft (7mm) high by half length.
Then halved the 10ft 6 " wheel base to act as a positioning for the W Irons etc.
It's not where he has drawn the W Iron.

What's wrong, normally its my maths wrong so that was all rechecked , so I plotted a 9ft 6 " base and a 10ft wheel base.
He's only gone and drawn the wheel base at 10ft and annotated it as 10ft 6in. So which is right his dimension or his drawing.

Why can life be simple?

 

Handy little tools that - thanks.

 

Having experienced that wheelbase lash up with the Tatlow diagram of the C8 I will be sticking to overall length from now. Then a quick check to make sure the wheelbase dimensions make sense before doing anything else.

Far too cold to do any 3D printing, so I have been finding new subject which would test my Fusion 360 sketching skills. Rob mentioned he liked outside framed wagons and there are only 2 NER wagons I know of, the G1 van and the C1 fish (not really open framed more planks on top of planks). After rejecting the G1 as I have 2 already I started studying an excellent Richard Lacey drawing from the NERA and an excellent photo of the van I realised it had quite complicated hinges and strapping around the doors so decided here goes another experiment. The drawing is of an early van the photo of a later van with revised hinges and door locking mechanism. Any way the basic van sketches were quite straight forward so onto the hinges and door locking mechanisms. After a number of brain frying sessions this is what I have got done sofar.



So a couple of questions:

Has anyone ever manage to sketch the fine chain which connected the cotter pins to the strapping? After many attempts I have given up.

The small rectangles visible on the doors and van sides are obvious to represent the fastening to hold the door open, but what did they look like, I suspect a hook and U loop type system. Any ideas?
