After dipping my toes into modelling in OO6.5 gauge I decided to see if there was anything a bit more interesting I could model, that might also be usable in OO9 gauge. I didn't have to look far as the Royal Arsenal Railway had an interesting little gunpowder van, which sat on a very similar chassis to the transfer wagon. Mark Smither's book on the railway contains a couple of small photos and a drawing (although I discoverd that the drawing is wrong in a couple of important ways) and I managed to find a few photos of a surviving example which is now at the Conway Valley Railway Museum. Putting these together with the existing chassis model I managed to produce what I think is a really nice little model. First in OO6.5 gauge...

...and also in OO9 gauge.

Design wise the model is a bit of a departure from previous wagons I've designed as in the end I opted for a mixture of 3D printing and etched metal parts. The reason for this is that with the external framing there is no orientation you could print the model in that wouldn't result in support wax covering all the planks, which would likely result in a horrible surface and the plank gaps being obliterated.

The combination of 3D printing and etched parts works really well together on models like this and I'll certainly take this approach again on any similar models in the future.

There are a few issues to finalise but hopefully it shouldn't be long before complete kits for both the OO6.5 and the OO9 gauge versions are available via Narrow Planet, price yet to be confirmed but I'm sure I'll do another post when they do appear.

Stop Blocks

Having previously produced models of the chimneys and finials used on some of the stations on the Lynton and Barnstaple Railway I've now been asked by the same people to look at another set of detailing items; the concrete and wooden stop blocks. While it turns out that they changed quite a lot over the years and no two appear to be exactly alike, research (mostly carried out by Chris Harvey) suggests that there were a few basic versions. Each block consists of a concrete post, some of which have a sloping back, and a wood block which could be either wide or narrow. From those details I've worked up a set of test prints that when painted look like this.

I had to take four separate photos as each stop block is actually made up of two parts that fit together and I only test printed one of each part. Essentially the wooden block has a peg on the back that slides into a slot on the front of the concrete block.

As you can see I've also made it so that an hex nut can be slotted into the concrete part, which not only allows you to use a bolt to secure the two pieces together (not needed really as the parts are a nice tight push fit) but to also bolt the buffer to the baseboard so that it might actual withstand the force of a train colliding with it; the bolt is made from nylon to make it easy to cut to length.

The height of the blocks was carefully chosen to allow them to be used in two different ways. For those who model the L&B and want the block to be the correct prototypical height then they can be mounted on top of the sleepers. If, however, you mount them direct to the baseboard (so the bottom of the block is inline vertically with the bottom of Peco 009 track) then the loop on a standard 009 coupling should just slide over the top of the block with the face of the coupling aligning with the wooden block.

Whilst these were designed at the request of a number of L&B modellers, hopefully they will be of interest to other 009 modellers. A a kit will consist of both a wide and narrow wooden block, a nut and bolt, and either a square or sloped back concrete part (you'll be able to choose which style you want when ordering). I need to order stock before they go on sale but a single kit will be £7 or we can offer a pack of 3 kits for £18.
