I saw a nice photo of an engineering train on the Isle of Wight in an rmweb thread about Wight Freight, but the photos disappeared before I saved copies. The picture showed lengths of rail on a train of short wheelbase single bolster wagons. I picked up some old S/H brass etches of unknown origin at a meeting a while back, so I thought I might reproduce this for 'Freshwater'. The etches perpetuated the old Tri-Ang trait of brake shoes in line with the W irons, so these were removed and parts of an old Association brass etch of brake gear was pressed into service. The wagon wheelbase is shorter than any of the brake gear on the etch, so it needed some modification. Association etched nickel silver axleboxes and springs, and cast buffers were added. Some square brass tube will form the bolsters, and small T-section brass, filed down to even smaller, added to the body ends to replace the rather poor stanchions on the etch. Because of the required modifications, and lack of locating aids in the etch, each one is taking 4 or 5 evenings to complete to this stage, so it is a long, slow process. Still, 3 down and 3 to go... Ian, Following on from Andy's comments I'm attaching some photos that I took on a visit to the Island five years ago when they were in the newly erected stock shed. Never miss an opportunity to take photos of wagons! David 5 1 1 1 Link to post Share on other sites More sharing options...
Yorkshire Square Posted April 16, 2019 Share Posted April 16, 2019 Made a start on the roof last night. As the building is low relief, I have compressed the depth of the building to bring the ridge into the build. I think I can get another layer of card on those chimneys though, toward the rear. 3 3 Link to post Share on other sites More sharing options...

I know use them myself in similar applications Nick You’re not wrong, it’s out of one of those Farish 101 parcels dmu’s that had two motor units. One was used in a Cravens 105 build and the other here. This 309 EMU uses Farish 7mm coach wheels in commonwealth bogies. They came from Farish Pullman coaches* along with the roofs. I grafted one set of frames onto the power bogie outer clip frame. * should add I also used the underframes and corridor connections, basically just throwing the actual bodies away. Seeing what the current prices are now I think perhaps today I would try another less expensive route......at the time (2014) they were obtained from Hattons @£12 each......

Chris No problem Chris While the wheels look to be a very tight fit, the wagon rolls freely and has passed a test using a multimeter. However, I think that I'll be getting some slightly smaller wheels in the future, just to be on the safe side. I also spent a little time on the ex-GCR bogie fish van today. I purchased some etched bogie stretchers a few weeks ago and modified these so that the overlays (cut from the original bogies) could be used. I then soldered together some of the axle box etches and added these to the bogies. As I've not fitted any retaining nuts (I'm out of stock), the roof is only placed on top of the body at the moment. I'll add the buffers once I've finished adding all the overlays to the body. I also need to fabricate some truss bars in the future. 10 1 6 Link to post Share on other sites More sharing options...
justin1985 Posted April 19, 2019 Share Posted April 19, 2019 (edited) Inspired by David Searle's article in the 2mm Magazine a few months back, but lacking a milling machine, I've 3D printed a little jig to use with the new single piece etched chair plates. It took a little adjustment (grooves 1.1mm wide rather than 1mm) but it works really nicely. I think one of the articles suggested grinding down a small screwdriver into a flat triangle shape as a pusher, but I found a simple push pin, with a few strokes of a file to blunt it and flatten off the sides, did the job really well. What took ages and was a right pain before is the work of moments! Justin EDIT - just to say I'm very happy to share the STL file with anyone else who wants to make one!

Atso Posted April 21, 2019 Share Posted April 21, 2019 I've just finished the ex-GCR Mac N etched kit. While it was certainly a challenge, it was an enjoyable one. I stole the buffers from a spare Farish loco body as they were pretty close to those shown in the drawings. No wheels have been fitted yet as I need to get some more N gauge 5.1mm wheelsets. 9 Link to post Share on other sites More sharing options...
RMweb Premium Izzy Posted April 21, 2019 RMweb Premium Share Posted April 21, 2019 Mass Halfords grey primer spray session. Catching up with all the stock that was in the painting queue. The first recent day on this (North East Essex) coast when a bitting wind didn't keep the undercurrent temperature down. Living quite near the seafront we are always amused by weather references to 'a slight onshore breeze keeping things cooler'......... So, half a dozen BR fitted van chassis, the Cowans Sheldon crane + lowfit runner, Cravens 105 DMU bodies, and the 309 EMU bodies. Give them a day or so to harden off, then decide what colours to apply...... Always find this stage useful for revealing anything that has been missed. In this case the door hinges on the 105. So out with the Slaters plastic rodding again as it looks okay to me on the 309 bodies and sits nicely into the etched grooves. All I need now is another warm day sometime next week, then I will have to choose the colours. Probably maroon for the 309 because I just haven't the skill for the later BR Blue/grey, but probably plain BR blue for the 105 as I can manage that.

RMweb Premium Popular Post Izzy Posted April 26, 2019 RMweb Premium Popular Post Share Posted April 26, 2019 Well, while the weather has been okay circumstances have meant I haven't been able to paint most of the bits given a coat of primer the other day......but I have given the Cowans Sheldon crane & lowfit some Precison paint by brush and after quite a tussle got some thread strung to finish of the crane. Tried nylon thread but that had a mind of it's own so some rather hairy cotton type thread was used instead as that could be held in place with cryno at certain points where it proved essential. Not the best result but will have to do until I can find something better if that proves possible. At least the overall effect is fairly reasonable.

RMweb Premium Izzy Posted April 27, 2019 RMweb Premium Share Posted April 27, 2019 Thanks for all the thoughts over the 'hairy wire', and the likes for the crane. I have been taking another look at the thread that I used, which doesn't look quite so bad at normal close-up viewing distance, i.e. what I can see though my glasses at around the minimum distance of about 9", but does appear a bit over-heavy. I measure it at just over 0.2mm. This is multistrand 100% polyester by Gutermann and is supposed to be coated and less hairy than others, which it does seem to be. Just not smooth enough for this small scale. I did think about coating it somehow but worried that it might appear even thicker and/or get stiff and un-workable. I've also looked again at the nylon thread by Korbond. This measures about 0.15 ( 38swg) but appears much finer/thinner because it is monofilament and has a reflectance about it. When I can I think I might try using this again, if I can work out how to get it to stay in place. The issue is time. Not that I don't have it at present, but it took several hours work to string the crane with the 'will do as it's told' polyester, and I can't really face spending that amount again for a while as It was very tiring work eye wise even under a good LED magnifying lamp. Plus I worry about any damage I might cause stripping the bits out of the crane to do it. We shall see.... regards to all Izzy 1 Link to post Share on other sites More sharing options...
2mmKiwi Posted April 27, 2019 Share Posted April 27, 2019 I concur with your thoughts Izzy, I don't think many would have batted an eye lid at the wire if you had not mentioned it. As you say it looks pretty good even in the photos with a plain white background. Sometimes the risk for damage trying to undo something is not worth the correction. :-) 1 Link to post Share on other sites More sharing options...
RMweb Premium Popular Post Izzy Posted April 29, 2019 RMweb Premium Popular Post Share Posted April 29, 2019 Well, those who know me will understand that I cannot resist scratching an itch, and the hairy wire was certainly one. Had I realised before posting the images how it was I would have thought again before doing so. So.... it has now been stripped down and the nylon 'wire' fitted. This did need some extra work in respect of holes drilling in the winding drums to help retain it in place (with cryno), and some minor damage repaired along with a further lick of paint in places. The laugh is that being translucent I found I had to wash thin turps based matt black over them to be able to see them at all....... Anyway, I think it was worth the extra effort as I hope the comparision shots will show. Izzy 17 3 2 1 Link to post Share on other sites More sharing options...

Nigelcliffe Posted May 6, 2019 Share Posted May 6, 2019 On my bench is more electronics. I was asked by the loco's owner to add stay-alive bits to a class 08, chassis from Association kit, body from Farish. The decoder is a Lenz Silver Mini, and was installed before the loco came to me. I've added a Zimo SACC16 stay-alive regulator (right hand end at top) and two 220uF tantalum capacitors below it (they'll sit behind the radiator in the 08). The SACC16 has been reduced to its minimum size, and then wires are added to reach the two capacitors which hang below the circuit main. Of note are the positive and ground pads on the Lenz decoder, which is where any stay-alive circuit starts. Simple to solder to, and recorded in the Lenz manuals for adding SUSI secondary decoder devices. There are four pads, the positive is to the top (red wire) on the upper photo, and the ground to the bottom of the four pads (black wire). The other two pads are for the SUSI signals and not needed for this use. There is space for more capacitors - at least three could be fitted above the worm housing and motor drive coupling. But, I found that 440uF was enough for 1/6th of a wheel revolution at low speeds without power, and that should be enough to deal with odd hesitations. Before the body goes back on, I'll be adding some thin insulation around the various devices to give extra protection against accidental short circuits. When there is space, I'm now using the SACC16 device, rather than simpler and smaller home-brew charging devices. This is in part because its quicker to use an off-the-shelf item, and because the SACC16 is claimed to be more robust against over-voltage.

Lacathedrale Posted May 9, 2019 Share Posted May 9, 2019 I finished up my single slip - I missed a joggle and/or set in the stock rails, and the switchblades on the K crossing are a little short - but it technically does function. I'm going to leave this as part of a diorama/photoplank I think: The body isn't perfect on this LMS cattle wagon, but I'm really pleased at how the underframe has come together - everything lines up and looks decent. It's in the paint shop now to come out in LMS light grey (D1840?): Unfortunately despite some assistance from @justin1985 and @queensquare my Jinty chassis just won't work.

Ian Smith Posted May 20, 2019 Share Posted May 20, 2019 (edited) One of the several things that have found its onto my workbench in the last week or so is my first bogie coach - a GWR Dean period diagram D37 Van 3rd (with a clerestory roof). This is one of Worsley Works "scratch aid" kits, being basically a floor, sides and ends, and clerestory sides and ends. Having put together Allan's GWR 4 wheeled coaches, I found the parts went together easily enough. A roof then had to be sourced, so I cut a suitably sized piece of 0.005" brass sheet for the main roof, and carefully rolled the 3-arc roof profile. Thinking about the clerestory element of the roof, I decided to go the same way that I had with my 6 wheeled coach from my own etch - that is to say I cut holes in the roof where the clerestory would go - the reason for this is two-fold i) I wanted to assemble the clerestory sides and ends onto the main roof and then enable the clerestory roof to be fitted afterwards, so I needed a way to get the iron into the clerestory to attach the roof from the inside, and ii) in the period I model the windows in the clerestory would still be glazed so I needed access to the clerestory interior so I can fit the glazing. General view of where I'm at - Underframe bent up and solebar/upper footboards fitted. Body basically ready for trying to fit clerestory roof. One Dean 8'6" bogie assembled. Because no bogies are provided in the kit, I am going to fit some of my own design. When I did the 6 wheeled coaches I included Dean 6'4" and 8'6" bogies on the sheet (only to realise now that the D37's actually had Dean 10'0" bogies!). However, until I do another etch this model will be fitted with Dean 8'6" bogies for the time being. The bogie etch includes brakes and footboards, but still needs the volute springs fabricating and fitting. The basic bogie as designed. The two-layer springs are a bit fragile until soldered (one of the springs on the far side has lost a "spring cup" on one end of its outer layer). The gaps in the footboard are to accommodate the volute springs when I've fabricated/turned them up. The supports below the footboard need a wipe or two with a file to thin them and make them less obvious. There's still loads to do, obviously the clerestory needs a roof. Both grooves will then need rain strips. The door vents need to be added above the doors, and the door G grab handles need sweating on. The gas lamps and associated piping will have to be added to the clerestory roof. The handrails added to the step end and the brake tell-tale, etc added to the other end. And of course there's another bogie to be made and the underframe needs all of its various fittings made and fitted. Ian edit : PS Out of interest how do others do their clerestories? Is there a better way? Edited May 20, 2019 by Ian Smith forgot the PS 4 4 Link to post Share on other sites More sharing options...
