Steve, Any updates ornew projects to show off? Duncan -
DrDuncan's 3D workbench
drduncan replied to drduncan's topic in 3D Printing, Laser Cutting, CAD & CNC
Some photos of completed late Victorian GWR narrow gauge wagons. Here is a one plank wagon, early ribbed buffers, wooden brake shoes and curved brake lever, with a red oxide primer. This is an early 2 plank wagon with low sides and no doors. Again, with ribbed buffers, wooden brake shoes and curved brake lever. Both are using ex-D&S etched w irons. Duncan -
SHMRC Portsmouth Model Railway Exhibition on Saturday 18th November 2023
drduncan replied to kipford's topic in Exhibitions
Demonstrating 3D printing I didn’t stop until about 3.45. I even had to proffer excuses to one group of listeners in order to get my lunch before the excellent catering closed. I suppose demonstrators are doing something right if they don’t get to see the show! Again there was lots of interest (I wish I was getting a commission from Anycubic) ranging from what is it and how do I do it? To more detailed questions about software and specific design issues - as well as what can go wrong and why. It was, from start to finish an excellent day. Well done Dave and Jonathan. Duncan -

Dear all, I’ll be demonstrating 3D printing again at the South Hants show at Admiral Lord Nelson’s School Portsmouth this Saturday 18 Nov. Do come along and say hello. Also Modelstock - the new owner of ABS Fourmost - will have on sale there my new range of resin printed GWR scratch builders aids to building 1, and 3 plank wagons as well as N6 loco coal wagons. Regards Duncan -
On my photon mono I just used a round file and filed a 1/4 diameter slot at the bottom rear of the printer cover. For the photon Mono X2 it came with a slot and it isn’t as precious about the kid position as the Photon Monos are. I also use a thermostat too (again for reptile tanks, came with the first pad).

Mid-Cornwall Lines - 1950s Western Region in 00
drduncan replied to St Enodoc's topic in Layout topics
Not able to take in the South Hants MRC show in Portsmouth on the 18 November? It’s usually a cracking one day finescale bonanza…. And just to kill the mood I’ll be demonstrating the dark arts of 3D printing there… Duncan -
I’d worry about elbows and indeed belly’s interfering with the siding on the baseboard edge. Original option A still wins for me. D

@Schooner option A for me. But If you are running into the goods loop and running round using the branch platform you seem to end up having to foul the main lines too at the cassette end of BM… Duncan

GWR 3 plank wagons appreciation thread
drduncan replied to drduncan's topic in GWR Rolling Stock: model and prototype
It’s looks like all osL211 nos 31401-600 were all recorded in the wagon stock books as having wood frames with iron sole bar plates. D -

Re 31401 onwards - I've had a look at the first 5 and the frames all are marked as wood with iron sole bar plates. I'll check the others and check back to you. Duncan -
GWR 3 plank wagons appreciation thread
drduncan replied to drduncan's topic in GWR Rolling Stock: model and prototype
The lot in question was built at Swindon, if I recall correctly, I’m afraid. Tony’s book is full of useful information on the earlier 1 and 2 plank wagons. D -
Does anyone know which lots, in addition to osL231 were fitted with fitched underframes (ie wooden underframes with iron cover plates)? Interestingly - and not very helpfully - the Wagon Stock Books I have seen covering the low numbers of osL231 do not say wood and iron underframes, just wood! Are the entries for nos 34001-34100 different? Regards Duncan

So, as a partial excuse for not posting for a while, I have been playing with a new printer - an Anycubic MonoX2. Some interesting findings: 1. It can accommodate 9 x 16ft (ish) long wagon bodies, if you print them at 45 degrees. 2. it is faster than my old photon mono. 3. Not only will it print 48ft coaches in a single print, but much to my surprise, it will do a 57ft coach at a 45 degree angle. It might even do 58ft one - if so lots of CADing GWR clerestories lies in my future. Duncan -
Yes it is. I think there is a website being set up but I don’t have any details.

James @Edwardian, How is the single? Duncan -

Shame. I thought it was the one useful contribution the felines made to the world. -
Dean 6'4" bogies - some queries
drduncan replied to WillCav's topic in GWR Rolling Stock: model and prototype
Not my period - I tend to loose interest after 1914 but I’d be surprised if any Dean period low roofed coaches were in revenue service in 1949. Some might be in use as workmen’s trains but you’d have to check the coach registers to be sure unless anyone on here has researched these coaches specifically. But to answer your question: almost certainly the upper footboards which were fixed to the sole bars would be in place. The lower footboards, these were removed either from in front of the bogies, or between the bogies , or both in the years after WW1. You need a photo of your type of coach to see what was done I’m afraid - there is not to my knowledge a hard and fast rule or date. Are you a member of the Great Western Study Group and if yes have you asked on their IO groups - there are some extremely knowledgeable people lurking there! If no do think about joining… Regards Duncan
