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!!

This is a first go at a 4mm scale print, it works in 7mm also!
I have been looking at all the parts and thought this was probably too many and the split for the tender should be like the loco.
I have yet to adjust these drawings as I went on to the Craven single 153/4. This has now been drawn in Stroudley condition with lots of parts already on the body leaving the handrails and lamp irons to be added. 

This is the 4mm and 7mm scale versions. They are two part prints for the body in one piece and outside frames with footplate as the other, for both the loco and tender. 

I have to adjust the tender drawing to print the top piece curving down at the front as per the Cudworth Goods tender. The drawing is correct, there seems to be some error in the slicing file that I cannot resolve so am about to remove that bit and redraw it in a different way. I have split them so that the springs are with the footplate and lower part. The upper print has all the parts for the body apart from the reverser which would need to be glued on to the cab floor.
I still intend to get the Craven version to be available also.

This is the photo of the 7mm Craven version as I built it at the start of the pandemic. The smokebox is different, along with a few other things. I intend to print this in the same style but with provision for the face of the driving wheel splasher to be etched.

So, some thoughts from you all please. Should I continue with the 3D printed, almost everything as one piece but split in a way that suits painting OR would you prefer to have an etched kit with a few parts in the 3D resin as I have developed above?
The chassis would need to be etched, as per the 153 photo showing the two part prints. 

Cheers, Ian

4mm Inside Motion parts for Slaughter Goods

 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.

These are b, c, d and a from the top.
You can, hopefully, see that the right hand crank drive is above the axle with the driveshaft towards the rear of the slidebars and the left hand crank drive is in front of the axle with the driveshaft nearer the front of the slidebars. The eccentrics are also in differing positions so the quadrants are slightly out of alignment when viewed from the side. The weighshaft has the bearings on the shaft and these can be affixed to the front of the motion plate. The assembly should be able to be fitted from the top and bottom of a running chassis. The parts could be glued together and then attached to the insides of the frames using the pump valves and the cranks and eccentrics can rest on top of the axle.
Very difficult to photograph!
£10 a set including UK postage.

7mm Craven Slaughter Standard Goods being developed

 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.

Cheers, Ian

Hornby 4 wheeler accessorising


Foot board and guards lower footboard

Footboard for non-brake vehicles

Hornby have provided us with brilliant renditions of near Stroudley carriages that are let down by, in my eyes, two main things: the grab handles and the footboards.
I have designed and printed these two types of footboards to be a quick super glue addition. 
One piece printed footboards for non-brake vehicles; £4 a set. One piece footboards for brake vehicles with lower footboard; £6 a set.
See later about grab handles. Roxey are available.

I have also designed a 4 wheel sprung underframe etch that fits the Hornby carriages beautifully, along with 3D printed 6 foot or 7 foot axlebox spring units and buffer sets, either one piece or two. A short length of spring wire is needed to operate the springing units.
The etch plus EITHER 6 foot OR 7 foot 3D printed axlebox and spring units with a set of one piece buffers is £12. Two part buffers instead of the one piece for an extra £2 or £4 a set if ordered separately.
3D printed Guards lower footboard set £3 if ordered with a chassis etch or £6 if separate.

I have also drawn up 9 spoke wheel centres - these are fitted to MGW P4 wheel tyres as shown, the first attempt to the right and the current, slimmer type, to the left. I haven't been able to try these on Alan Gibson wheelsets yet as I haven't got any! A set of four 3D printed centres for £4, you provide the tyres and axles.
The 3D printed grab handles are shown on the Hornby 1st class carriage above which is sitting on one of my etched chassis. These grab handles have either a base printed at 45 or 90 degrees, suitable for whichever situation, as required. They just superglue into position, very easily, if you have a small pair of tweezers to hold them! These are a pig to get printed so I would only be persuaded to sell these if people twist both my arms. Roxey's etched brass ones are available.

Postage would need to be extra for all the above. £2.50 minimum as they would need to be large letter postal rate due to the thickness of parts.

I intend to get some other Hornby carriages accessorised in the next few days so this blog will be updated when there are some other photos to show.

Cheers, Ian

Gauge O Guild Virtual Model Railway Show


Yours truly with a bit of Brighton content! Looking at how to design in 3D, a chimney for Grosvenor and then all about the 3D printer and how it prints the chimney and what is required to make the print useable. I will post Youtube links on here after the event. Cheers Ian

Carriage Smoking transfers

 I will print two styles in 4mm and 7mm.

£5 per sheet for 4mm and £8 per sheet for 7mm. Postage to UK included.

and the photo below is of the actual transfer, I have reversed the whole thing so it can be put on the inside of the 'glass' as a transfer. Quite difficult to photograph! Cheers, Ian

Just tried applying some of these and because they are on the inside, I have also just put these onto a piece of clear plastic along with some other bits for the saloon carriage windows I drew at the same time, about a year ago, when I was trying to get things printed and failed. These are now printed with the Ghost white toner on the HP LaserjetPro M254dw that I purchased so as to be able to move things on. They seem to work nicely. I have used Microsol to bed them in a bit but didn't really see any difference from plain tap water.

The sheets above are 4mm, the examples on the clear plastic sheet are a mixture of 4mm and 7mm scale. The Smoking Carriage was used on the long window thirds of the Stroudley 4 wheelers in case anyone was wondering!

The ones at the bottom were when I learnt about the reversing of the print!
Cheers Ian

Renamed and renumbered 7mm Dapol Terrier

 Just been trying out the names and etched plates to rename and renumber a Dapol 7mm Terrier that had been Brighton with the gold medal lettering. I used a curved scalpel blade, very gently, to scrape away the wording and name off the existing tank side and removed the plastic numberplate by just putting the tip of the blade under it and twisting very slightly.

I then applied a very thin coat of Vallejo 70.510 gloss varnish using a broad brush and waited for it to dry - about 20 minutes.

Next was applying the white underprint layer, to ensure there is white in the final name and to allow the coloured toner to show as if printing on white paper - which is what the printer is designed to do.

The next time I do this, I shall experiment with Microsol or Microfix decal solutions to see if the edge of the transfer can be softened further. I will also try another type of gloss varnish to see if it makes the carrier film disappear better. The white was allowed to dry - again about 20 minutes. I did the other side whilst waiting and filed and smoothed the tabs off and painted the etched plates a dark blue and used a black sharpie marker to put the lettering in before a rub over with abrasive paper to leave them as per the photo below.

Then another thin coat of the gloss varnish over the white to seal that, let it dry before then applying the coloured part of the name. Another thin coat over the dried coloured name and a tiny drop of superglue for the etched number and works plate and I am ready to reassemble the parts for the photo. I am correcting the position of the cab gauges and a few other detail improvements also. I will post a photo when I have completed all those, later.

The lighting that the photo is taken in really affects how the IEG looks doesn't it!

I can supply any 7mm name for a Terrier as well as the etched plates as shown here and below. £18 including postage.

Above are the names just printed on white paper with the etched number and works plate alongside. I do have another for 36 Bramley if anyone wants one by the way. 

Now that I have got the names sorted for 7mm I am going to start development work on the Stroudley lining and lettering for 4mm, which I know a few people are waiting for! The number and works plates are all available already, as they are for any 4mm loco with numberplates and the works plates for the I3 class are also available as per the October 2019 post 

Cheers Ian

Loco and tender transfers for Stroudley Passenger Lining, in 7mm scale presently

 I have been drawing more Transfers for the last week.

For the loco lining, I am doing each loco separately at the moment with a few spare bits on each sheet, going through all the EB Models offerings and some others I need also. So far I have the G Class, D and E tank locos, Stroudley inside and outside frame tenders and Stroudley lining for the large Craven tender completed.

I am drawing over scans of etches so they are designed to fit.


The photos show the E1 back left, D1 back right and G to the front of the top photo and the bottom photo shows the Stroudley inside frame, large Craven tenders and Stroudley outside frame from left to right.

I have Richmond class, Belgravia class, 18/21 and Dieppe and Grosvenor scanned. The Richmond will include some extras to fit the B1 from Albion or it may be a completely different sheet depending on what I can fit on, and there will be an E4 and E5 that I still need to scan.

I will also do a Terrier and anything new so that they can be completed.

About a third of the names have now been sorted, and I will be doing them all and printing to order for those to go out with the lining. Same two layer application. I haven't printed any of those yet.

I will also be offering a 'finishing service' of lining, name and etched number/work plates, when the etchers have got back to their normal two to three week turnaround rather than the eight it is taking at the moment. 

I have not yet set any prices but am trying to keep it to something like £12 per loco or tender. I will also need to get the 4mm versions drawn up - I shall make the white and red lines a little thicker than scale thickness otherwise I don't think they will show at all. The white or red lines on the main loco body lining is 0.073mm thick in 7mm and can be seen okay but if that reduces to 4mm scale, the line will be only 0.042mm thick which is pushing the technology a bit too far I fear. I shall put some experiments up on here to see what others think.

Comments always welcome.

Cheers, Ian
