Just started to put together an old 7mm Albion Models D1 tank and found I haven't got all the castings, so decided to draw and print my own. Also, as I now have a higher resolution printer, I printed them at 4mm scale as well as 7mm scale. I see I haven't included the 4mm springs but the rest are there.
Parts drawn are:
1. Motion drop in with early style pump. 2. Cab backhead, splashers and reversing gear. 3. Cab rear with brake, coal door, sandbox/toolbox, dampers. 4. Chimney. 5. Cylinder cover and angle plate. 6. Dome with safety valves. 7. Whistle. 8. tank top exhaust steam dome. 9. Clack valves. 10 Cab roof. 11. tank top water fillers. 12. Can/guard communicator. 13. Cab Steam/Brake pressure gauges. 14. Smokebox door and dart. 15. Lower firebox/ashpan sides, front and rear. 16. Sandbox filler caps. 17. Smokebox front cylinder screw lubricators. 18. Front wheel lubricator oil boxes. 19. Smokebox LHS and RHS lubricator/blower controls. 20. Brake blocks for leading and driving wheels. 21. Brake blocks for trailing wheel. 22. Westinghouse pump. 23. Leading wheel leaf springs. 24. Driving wheel volute springs. 25. Trailing wheel leaf springs.
4mm to left, 7mm to right.
I have just realised I didn't print the 4mm loco springs.
I aim to produce a set for the E1 also as I have a couple of them to build as well.

What I have been up to whilst battling with a nasty bout of Tinnitus - Craven 153 and Cudworth Goods
Having had a few months of really awful racket in my head that really affected thought processes etc, I started a few weeks ago to manage a bit of time on the 3D graphics. It started with a half hour at a time and has gradually increased to about two hours before I just have to stop and do something completely different.
In March showed the Slaughter Goods in 7mm, a trial etch and 3D resin printed parts. I am hoping to be able to start the trial etch assembly soon - Tinnitus really doesn't help here - so I realised in the meantime that the wheelbase was the same for some of the other 'Standard' Goods. One of which had a Cudworth coal burning firebox - eight foot long!!

I finally got the Slaughter Goods inside motion drawn in a way that they will print consistently. There are four parts; left hand (a) and right hand (b) slidebars, which have the ram pump on their outer side; the valves (c) in the centre with their eccentric rods and links and connection to the underside of the boiler; and the lifting links and weighshaft (d) and weight that attaches to the front of the motion plate. The lifting links on this loco attached to the top of the eccentrics quadrants.
This shows the four parts in roughly their correct orientation, the valve rods should be slightly lower and the eccentrics slightly higher.

I think many of you know I am designing and making more in 7mm scale nowadays and have been wanting to re-scale the 4mm Craven Slaughter Standard Goods for a while.
Here is a photo of the etches and some of the 3D resin parts for the 7mm version.
There are still a few parts of the 3D designing to do. One major part that I was unhappy with was the dome, safety valves and levers unit. I have now redesigned this to be made up of four parts as follows.
I have just pushed these parts together for a photograph, no glue yet. I am a great deal happier with this aspect now.
So, now for a test build and write the instructions.
I am awaiting some wheels for the loco so will start on the tender and probably publish it on RMWeb with a few shots here also.
