Back Together Again

By nigelashton

Thanks to Richard's nifty etch bits, my Britannia is back together in its improved form.

The wheel weights were added and the wheels painted (Tamiya Nato Black if you're intersted). Then all the gears and chassis bits were checked to function with the replacement coupling rods being sloppy enough to avoid hindering the gears.

The connecting rods have huge ends and we had the idea to cut these off and splice on  closer to scale big ends (bottom row in this picture). The original parts are on the left, replacements on the right. The return cranks are also much smaller shown in the top row.

So after several bouts of dismantling, fettling and re-fitting the Brit has been re-wheeled, re-rodded, renumbered and renamed and looks much more becoming. After the completion of my Duke named Mercury, I decided to call the Britannia the same name. This was a Western Region machine and it didn't have the replacement smoke deflectors, so was a good choice all round. Cabside number transfers and new etched nameplates were from Fox.

So the front bogie is Richard's etch with Association wheels, the drivers are Association, while the rear truck and tender wheels are self-turned on the lathe. They are mostly hidden so the slightly thicker treads won't be noticed. I may well change the tender wheels when Association spoked wheels with the extended axles become available.

So here we have a picture of the completed model on Llangerisech, well over weight for the line, but this is where Rule One applies. Like the Blue Pullman, and the Western (currently being re-named and re-numbered as well to become Western Explorer), I had the OO versions as a kid. In fact, along with the 3MT tank and the HST, I have now pretty much got everything from my childhood replicated in much finer 2mm form now.

So here we have the finished article. The signalman with the tablet pouch and hoop is the delightful item from Modelu. I can even claim that the 3D printed people are Cambrian!

Brits In Pieces

By Richard Benn

The November meeting is our last of the year (as Christmas tends to get in the way).  As usual there was a lot of interesting discussion but a lot of activity as well.

Nigel and I are working on converting a pair of Dapol Britannia 4-6-2s. That's Nigel's on the left, with standard Association bearings soldered into the Dapol bearings amd reusing the Dapol gears. Mine on the right will utilise the new Association bearings and gears from the shop. Taking the Brits apart was not easy and required glued joints to be broken.

We have come up with some etched parts for the bogie, coupling rods (fluted and plain with the ability to have both as several locos did), balance weights, plus a couple of pieces which will hopefully allow us to utilise the majority of the Britannia valve gear. You can see the first test etches below (excuse the poor photograph - the light in the room is not the best).

I am going to check the fit of the coupling rods and Nigel is checking the rest. If it all works we hope to do the same for the Schools. That's mine on the right below with the Dapol Pannier on the left (both also in pieces). Nigel also has a Schools to convert. The Brit and the Schools are both diversions for us as neither fits with our main projects, but this is a hobby and it does us good to do something different once in a while.

The Schools came apart with much more grace. The bearings are the same diameter as those for the Pannier - they are longer but that is irrelevant to us - so I ordered an extra four for the Schools.

Alan was lining a Maunsell coach built from a Chis Higgs etched kit.

Guy was building track, or rather re-building track due to a series of unfortunate incidents.

David was assembling DGs, here seen doing the most fiddly bit - fitting the tongue.

Nigel also had his test track and I managed to snap a few locos as they whizzed round

Show and Tell

By Richard Benn

There's been little posted by us recently but that doesn't mean we haven't been busy. Here are a few of the things we have been working on.

Improving Farish BR1 Bogies

By Richard Benn

No posts from me for a while as I have been re-wheeling various Farish wagons (spurred on by a recent stint helping Nigel exhibit Llangerisech). The quality of these wagons is such that often there is little work needed other than swapping the wheel sets (leaving more time for weathering) but that leaves me nothing that is particularly finescale to report!

Whilst the Bachman Farish MK1 coaches are generally of this high standard, the bogies have one problem which lets them down in my eyes - the brake shoes are in line with the bogie frames rather than the wheels. This is the standard BR1 bogie after fitting with 2FS wheels (click for a larger picture):

The Association provide an etch of brake shoes that could be made to fit with a bit of effort, but as I have rather a lot of coaches I wanted a solution that needed minimal effort on my part, so I came up with the following etches:

IMG_2125

 

 

 

 

 

 

There are two different types, one for use with the NEM pockets on the coaches (for inter-rake connections) and one for the outer ends of rakes where DGs are fitted. The only difference is a gap for the NEM pocket and the loss of the brake cross rods at this end. These fold up quickly to give assemblies like this:

IMG_2126

 

 

 

 

The moulded brake shoes are easy to remove from the bogies with a couple of cuts with a scalpel. The assemblies are then glued inside the bogies locating them accurately using the raised boss where the bogie pin holds the bogie in place, like this:

IMG_2127

 

 

 

 

The finished result looks something like this (I would usually paint them before fitting but left them in the metal for illustrative purposes):

IMG_2132

 

 

 

 

 

 

I think the improvement is worthwhile but I'd be interested in the views of others. Assembly and fitting takes about 15mins per bogie. The cross rods are visible from some angles but once painted and weathered I doubt anyone will notice them. I'll know they are there!

IMG_2133

 

 

 

 

 

They are not perfect - the folds that position the cross rods are still out after two test etches, but this is hidden and it all lines up with a bit of tweaking so I am quitting while I am ahead. I had also hoped they would fit the Commonwealth bogie and they nearly do but need a bit of filing to make them fit perfectly. As the inner brake shoes are invisible on the Commonwealth bogie it may be worth creating a simpler design for this (if I have enough Commonwealth bogies to make it worthwhile).

The older bogies on the Farish Suburbans (with the moulded Rapido coupler) require some minor modifications before these etches will fit and even then there is no raised boss for location so it would have to be done by eye, presumably fitting the wheels before the glue sets in order to check for clearance. (These older bogies are not as good as the new type and I am going to consider replacing them.)

I am not going to sell these commercially (the time spent rectifying the minor faults and providing instructions etc. would make it uneconomic) but if anyone wants some at cost on an as-is basis let me know via the Wealden group contact email and I will order enough when I order mine.

Meeting Update

By nigelashton

Last Saturday saw some of us in our usual venue in the council building in Uckfield for our monthly meeting. Although we were a little down on numbers, we still had five of us discussing projects and ideas while doing some model making. Gareth was doing more coach lining and apparently managed sufficient corners to match the previous two months' efforts. Calculations revealed that the coach rake should be finished some time in late 2017 at the current rate!

Dave was working on some wagon chassis, using his self-built RSU while David was working on some DG couplings. We admired David's completed Langley horse-drawn vehicles and although I didn't get a shot, these did appear on the Kent and Essex group blog recently. Seeing them in the metal revealed even more detail.

I was replacing the quoins on the station building for Llangerisech. The earlier ones were cut from self adhesive paper using the Robo cutter, but had a habit of peeling off and looked a little too mint. So I used the cutter again to cut strips of the same width, but then could fold the paper and cut the strips evenly to length with a scalpel. These strips can then be glued on in alternating patterns using decent glue so they won't peel. A little weathering will highlight the morter courses. The plan is also to do some elements of interior detail so that doors can be left open.

Conversation revolved around Scouts, future exhibitions, using acrylic paint on FUD 3D prints as enamel is tricky, and the changing face of commercial exhibitions. I also gave an update to Guy about the new cassette system on Llangerisech as he missed the previous meeting, so I have included a couple of shots of this too.

Oh and Guy was doing some unfathomable Warhammer thing that was given to him by his brother......

Notes From Our February Meeting

Last of the Year

By nigelashton

Today we held the last Wealden area group meeting for 2014. As meetings are on the 4th Saturday of the month, the theoretical December meeting always clashes with Christmas. So the next meeting will split the difference and be held on the 10th January then we revert to the 4th weekend in February. With us so far?? Good - I'll continue.

We had a good turn out with Richard, Dave, Gareth, Bob, David and myself present with a few items being worked on.

Topics of conversation included the Arnold 5BEL (Richard and Gareth already gloating in posession),the state of the Brighton Line, through tickets and forthcoming exhibitions.

Projects being developed included my GWR Mogul, with the splashers being added. I had already turned some cups on the lathe and cutting the splashers out of the circular cups was done during the meeting. The pictures show the machined disc and the last splasher being cut from its partner. The boiler and firebox are cast resin while the cab and footplate are nickel silver all to fit over one of my Manor chassis kits with suitable afjustments. The tender is one of the Dapol items avaiable from the Asssociation shop.

Gareth was lining out one SECR carriage, with another finished one on show for inspiration. As ever, Gareth's modelling quality exceeds virtually anything else designed to run on 9mm gauge track. I'm itching to change the wheels to 2FS one day.....

David was working on some early GWR wagons in red oxide. The Western did exist prior to the 20th century and some of the earlier colour schemes were different to those most of us know. As all this pre-dates living memory and colour photographs David has the ideal answer to any rivet counters. He was using an interesting little vice  to steady the wagon body being worked on, as shown in another picture.

Meanwhile Richard was refining points on some of the wagons referred to in an earlier blog, among other things making new coupling loops.

So that was us done for 2014. Plenty of time to make modelling progress over the festive season and we'll all congregate back in Uckfield in mid January to share what we've been up to.

The pictures are pretty much in the order of the text above. Double click on any picture to see more detail.

It's Show Time!

By nigelashton

Evening  all.

Well  all the modelling activity culminating in the production of a second Collett Goods loco did produce a nice runner. First picture sees the running in session on the rollers. I think that was Thursday some time.

Today saw a bunch of us at Aldershot for an excellent show and an AGM thrown in for good measure. I took a couple of shots, during the set up phase when a lot of locos were in the shed area - it never got that crowded in normal running.

As this was the first time running the layout in its 1930's guise, I feared a degree of finger prodding, but things could have been worse. We found the Jones goods and the two Colletts pretty reliable. The 2p was a little variable, but fine once moving which is a little odd. Tre Pol and Pen had a couple of "moments" but benefitted from tweaks done during the course of the day. The Pannier pilot proved very able, but I spent a lot more time cleaning and re-cleaning the track throughout the day. I don't recall any real problems with the Manor, but David or Richard may tell you differently. We sidelined the 45xx fairly early, but I do have a plan to improve it soon.  A couple of coaches have had running issues, and as usual it is a question of identifying and rectifying these. Only through continuous monitoring will we improve things. Even the diesel stock went through this phase, so I am hopeful of seeing imporovements in reliability tomorrow and at future shows.

Anyway, it was good to see so many 2mm Association folk today and share ideas. We need to entertain the general public more tomorrow, so a long clean will be the starting point of the day.

Second Helpings Part 3 and Timetable Developments

By nigelashton

Hi,

It has been a busy day. I made the most of dry weather this morning to do some outside carpentry to mount the screen we will use to display the timetable to our audience. The screen is an old 15 inch one that my wife used to use before a new widescreen edifice took its place. A frame that allows us to attach it to the front of the layout but angled upwards gives us the ability to display information without distracting too much from the layout itself.

David has been doing a large amount of work on the timetable itself based on some real items for Pwllelli - Llangerisech's mythical neighbour! A concoction that is based on a semblance of reality helps us place the layout and lends a sense of purpose. Trains will be shown along with their destination or origin. The first picture shows things mocked up, but gives no idea of the amount of time that David has devoted to researching this and coming up with a workable item.

Once back inside, the last bits of the Collett Goods were put together. The tender uses the Association 8mm driving wheels with extended axles, but with the extensions turned down. On the old Manor models, a phosphor bronze strip had indentations in the form of cups, so the extensions were turned to points. On the newer version fitted to the 28xx and new Manors, the strip has changed to one with holes. The result of this is that the points need to be turned accurately to 1mm diameter. This has the benefit of extra sideplay, but means that a lathe is really needed to do the conversion. However, the lathe time was less than half an hour for me.

The chassis and wheels have all be painted, so it was really just a bolt and fit together job. The main advantage of the design is the ability to build then separate the worm carrier, so once the centres are established very little fettling is needed. In fact this one went together first time, so the measurements must have been accurate.

The intermediate gear (30:1 plus a 16 tooth gear) was mounted on stub axles and the rear wheels and final gear (20 tooth) mounted then checked. All OK, so the worm carrier could be fitted and the gear train checked throughout. Removing the worm carrier and completing the other axles allows the quartering and coupling rods to be sorted with all the gears turning.

The body required some plastic removing from around the firebox area to allow the drive shaft from the tender to pass through. All that remains to do is to finish soldering the crank pin washers, fit the driveshaft and bolt the body on with a new tender drawbar. The final picture is just a dummy - you will have to come to Aldershot this weekend to see if it runs OK!
