Building and completing my 4mm 3D Printed GNR Coaches

I had a thought.

 

Since you are about to slightly rework the kit...

 

In post #2 you show the reinforcing triangles for the floor to end joints plus some extra strips to reinforce the tops of the ends.  What about adding reinforcing triangles to the ends of the roof instead of reinforcing the ends with extra strips?  I'm assuming that if they were only as deep as the roof then they would not adversely impact the printing process.

I have now made the revised models available for sale as follows:

https://www.shapeways.com/product/VHCTRGFA3/gnr-dia-155-composite-6-wheel-carriage-kit

https://www.shapeways.com/product/5377ZVL22/gnr-dia-245-third-6-wheel-carriage-kit

https://www.shapeways.com/product/XQ6LZ7JJ9/gnr-dia-303-full-brake-kit

 

The kits now include solebars with integral stepboards w-irons, axleboxes and springs, ends with integral buffers, thickened ends, torpedo vents and lamps. The Full Brake has also had the pilot holes for handrails increased in size.

Unfortunately this now uses far more resin than originally and the revised price reflects that.

 

The following images are of the mouldings before any removal of residual oil, so not the easiest to photograph.

Life has definately had it in for me lately with a distinct lack of free time.

 

I have finally had a chance to wash the latests prints in IPA and give them a quick spray with filler primer so better photographs could be taken.

 

The full brake, now with added components:

The full first:

Closeup of full brake showing the additional parts. Hopefully you can also see where the new hole guides have been added to the sides to aid drilling for handrails:

OK, I admit it: having to modify the Bill Bedford LSWR W-Irons is a pain. In another topic I did suggest to Bill that he might like to consider adding the distinctive GNR W-Iron to his range. His response was interesting: "I've given up designing etches, especially these small frets, but there is nothing to stop anyone else drawing up a similar arrangement for prototypes that are not included in the present range.".

 

After thinking long and hard about this I plucked up the courage to approach Eileen's Emporium and offer to produce artwork for them for some Bill Bedford style GNR W-Irons suitable for 3'7" wheels. I did consider whether to change the springing design but in the end decided that I really could not improve of Bill's design. I based the frets on Bill's LSWR product, my preferred arrangement for these vehicles. The resulting etches are now available direct from Eileen's: https://eileensemporium.com/eileens-emporium-products/product/9108-1907-gnr-wagon-w-irons-for-3%E2%80%997%E2%80%9D-wheels-4mm/.

 

This is what you get on the fret:

They fold up to produce:

Hope they prove of interest.

Hi Andy,

 

Taking the composite brake in Ingrow as a guide, if it's the same style, the first has blue seats, and the third has a red colour. Hopefully these photos will help.

Hi Mike, I'm not sure if posting pictures of finished models from the kit on your own thread is the done thing, but I thought you might like to see a completed model (please excuse coarse track, couplings etc). I used the Brassmasters Cleminson Truck, partly just to see how it was to build - very easy and runs like a dream, though the very short wheelbase (20') helps of course. I can live with the loss of underframe detail (whcih is partly hidden by the low double stepboards) for the nice running - many thanks for producing these great kits! :)
