Thanks @innocentman, that's really useful and the tender looks great. Would an etch be available for purchase please?

 

Many thanks.

I'll PM you

Seems to be a bit of interest on the Fowler High sided tender.

Below is an extract from Model Railways, January 1974 with a table detailing known tender allocations to various Jubilees, Patriots and 4F's over the years

Here we have a lined green version which is intended for 45539

I did a similar thing when designing an etch for an LMS Patriot chassis

I drew all the component parts and then thought I will double check the geometry against the drawing I had just to make sure I had not done something dumb!

Worked out well in the end

I also have a Brassmasters 4mm kit to build in EM with the inside motion. Enjoying the discussion on the 4F inside bits, its nudging me to get that box off the shelf for my next project!

Best regards

That sounds good Fred. The melting magnets happened when the push-button contacts welded up (see above). I didn't calculate the true magnetic flux but when I was deciding what gauge of wire to use I used "ampere-turns" as a comparator.

 

I wind the coils using the time-honoured method of chucking them in a hand brace that I turn slowly while feeding the wire on. If I'm careful, I can get about 800 turns of 34swg wire on to the bobbin.  That gives a resistance of about 16 - 17ohm (see above) and with a 12Vdc supply a current of about 0.8A, so about 650 ampere-turns. If I use 32swg wire the corresponding values are 950 turns, 7.5ohm, 1.6A and 950 ampere-turns. I've also got some values for 36swg wire somewhere but I can't find them!

 

Broadly, if you use thinner wire the resistance goes up faster than the number of turns, so the pulling power goes down.

 

As I wanted to keep the current below 1A at 12Vdc I decided to standardise on the 34swg version. It has enough pull but with experience I think upping the voltage to 24Vdc and hence the current to about 1.5A will still be acceptable and will double the pulling power and so help with "sticky" couplings (which too many of mine are).

I think I need a laboratory!

I will dig my old uni text books out and refresh my memory on how to find the best compromise between number of turns, resistance, current, armature length etc

Make sure they are heat resistant. I made my first few magnets with plastic bobbins. Big mistake - not only did they distort when the coil warmed up but sometimes if I wound them too tightly they'd just snap. Now I only use metal ones.

 

The 3D FDM printing process is thermal and relies on a thermo-setting plastic, typically ABS or PLA. Other materials are available but all print at around 180 -230 degrees C. More than happy to print a few bobbins for experimentation purposes.

Although I have to wonder how long you are keeping the magnet on for it melt. Sound we need some experimentation, left and right hand rule stuff to a maximise the magnetic pulling force while minimising current flow

That's a very good suggestion, I can't really help much since most of the components I use come from large dumps of "spare parts" and I don't always know where they came from. Next installment on the C14 will demonstrate this.

The list of parts for the Fowler came from Inocentman's trawling round the stands at the York show which isn't exactly a viable option at the moment.

It was my intention to do the same for the Stanier 3P as I did for the fowler, but alas not possible at the moment 

I have been looking online and trying to do a list but it’s not easy when you can’t see them in the flesh and compare them to a drawing

Something 1Co-Co1 and EM gauge (judging by where its sitting in your test track)?

Thanks for your reply. Never heard of those. Have I understood correctly that those tools don't have indexing? 

David. 

Hi David, 

you are correct, they don’t have indexing. It does have a fence to enable straight lines to be produced. That’s not a problem in this particular loco as Mike has kindly half etched the rivets into the kit.

You've done a very good job on those rivets (and everything else). What did you use to punch them? 

Hi Daddyman,

I used my trusty Midland Railway Centre riveting tool.

I managed to givea Black 5 a little gentle "weatehring" at our show in Leeds this weekend.

 

Found a colour photo of the loco.. so a quick wash of my usual ink.water and a drop of washing up liquid then added some weathering powder ..mostly soot black, followed by a bit of dark earth for the road dirt on the front of the cylinder covers...no rust on this loco!

Cheers Baz, much appreciated

Its been a while since we have had a post on the CELF page.

It has been a bit quiet with members of the team on holidays or undertaking home renovations so not much change on the layout.

We have had a couple of additions to the stock roster for the class 1 passenger trains and express freight.

First up is a loco often known as the "Royal Dragon" by the footplate staff, 46153 "The Royal Dragoon" built from a Comet kit.

And second we have yet another 8F, this time with a Fowler tender. The loco is a a mash of an old K's kit, comet chassis, tender & cab, with Alan Gibson wheels and chimney.

Both are powered using Mashima 1428s and High Level gearboxes

Very nice Jamie, looks great

Another show over. All back in the clubrooms before 8pm last night.

It was an experience taking a model of a real place to the the place. Some wonderful feed back and some great stories about the folk on and around the railway. We even had a visit from a former signalman at Chapel-en-le-Frith Central. 

We have also been lent some documents (more on those later) and have made contact with a few people who have photo's to share and a house we can measure on Midland Road (thank you Seahorse of this parish).

Dr John (left of picture below) was kept busy taking to the public and hearing all the stories and feedback

Big thanks go to to the New Mills and District Railway Modellers, for the their invite and hospitality. They liked us so much that we won couple of awards from them, Best Visiting Layout and Most Popular Layout.

Well the layout is all packed up ready for its next show, which just happens to be in Chapel-en-le-Frith.

It's the New Mills and District Railway Modelers show this weekend (23rd/24th Feb) at Chapel-en-le-Frith High school. We are really looking forward to this show and hope to meet the people of Chapel and the surrounding district.

We have already had engagement this week on a Leeds MRS Facebook page post from a few people who had family who worked on the railways around Chapel-en-le Frith Central and South. Hopefully we can meet a few more at the show and hear a few stories about the station, its people and its operation. (https://www.facebook.com/Leeds-Model-Railway-Society-CIO-255524804592290/)

I've tried this sort of thing before and they always dropped off in the shed - probably the damp atmosphere in winter. Since then I've been using large cable ties pinned under the boards but I'll do this later when all the wiring is in place.

I screw them to the board (belt and braces). Have a look under Chapel on Friday

Last photo from the temporary use of the back bedroom (required for its normal purpose this week).

Two baseboards are a tight squeeze in here, one of the beds had to be tipped up to make room to get past. First groups of pointwork laid, wire and tested now. The next group will straddle the next baseboard joint so that will have to wait a bit, Templot drawing set out to make sure everything will be in the right position.

Up corner board and first board now assembled in the shed, trains can now run on to it from the fiddle yard using the link switches.

 

More wiring work done in the shed with the board on its side on a table, much easier than grovelling on the floor underneath. Wires and point motors labelled as I go along now.

 

Tidied a bit and plug attached, the black wire is the point motor common, the green wire sets points to normal, the yellow wire sets them reversed. This is the system I devised for Carlisle with split potential wiring from two transformers.

 

Appropriately an O4 is the first loco to run on the new layout, this would be a returning banker tender first on the up line, it will reverse over the crossover and slip to get back to the banker siding.

Can I recommend some of these

Thanks to all who attended the show, visitors, exhibitors and and traders. Everything is out of ths halls and back in the club rooms . And now we are having a relaxing pint in the Tin Hut!

Once again Thanks! And see you next year...

Thanks Nick. Thanks to you and your members for inviting Chapel and looking after us this weekend, we really enjoyed the show.

If I may be so bold, seeing the stand number sitting on the scenery and a loose A4 information sheet just stuck on the front of the layout spoils the whole look of what is otherwise a very professional presentation. Fixing the stand number to the fascia, and making the info sheet fit neatly on the front, would make a huge difference.

Point taken

Good day was had at Normanton and Pontefract show today

Big thanks to the NPRMS team for making us welcome. Great show with some cracking layouts.

Couple of pictures below from today: -

Hope you're going to run them with the links in the short position!

If the buffers were sprung I would certainly giving a go!

One small design idiosyncracy to be aware of..... 

I was hoping to get away with a Smith's Instanster on the front wagon and one on the back with an oil lamp for my rake. (All of our loco fleet runs with Screw links both ends) Kadee #18s looked about the best option for ease of use along the rest of rake. Forget that. the 'NEM' pocket isn't an NEM pocket in the strict sense. KADEEs don't fit and are loose in the housing sliding in and out and not giving a reliable gap between wagons. When pushed right into 'NEM' housing they also foul the outer axle on the bogies, not good. The options are therefore use the Hattons tension locks which look like a wagon specific design (nope, hate them) or fit Smiths Instanters to the whole rake.... oh well here goes. That is actaully reasonably straight forward as the chassis and buffer beam there is plastic and the model can be slotted relatively easy for the 3 link/Instanter to be glued in place. ****You have been warned****

I have purchased a rake of 16 to use as the full train on our club layout Chapel-en-le-Frith.

The couplings we use are DG's (Available from Wizard Models). Rather than fit all 16 with DG's I opted to do two rakes of 8 with a DG at each end and Smiths Instanters in between.

As you say the chassis is plastic and does allow simple modification to allow the fitting of the coupling hooks, although I went the whole hog and sprung them as well. I suspect the spring will never come into play given the mass involved. I have included a couple of pictures below

Innocentman is doing a 3d printed load "base" (It is on the Chapel en le Frith thread on RMWeb).

 

Noch do a lightweight limestone ..I would give you the id but I have passed my bag onto innocentman.

The Noch product Barry O mentions is 95800. 

Also the 3d printed load bases can be seen here
