7mm Rising Star/Slaters LNER F8

[Robpulham]

My mojo has been lacking for a couple of months or so and I was struggling to decide what I might do to try to get me back into the swing of modelling. While on holiday last week after listening to me huff and puff about building different tank engines, Chris had the idea of conducting a lottery to decide for me.

I have 8 tank engine kits in the pile so I wrote out the names on some strips of paper and Chris folded them up. Initially I though thast she was going to put them in a bag to pick one but to make it a little more fun and long lasting she divided them into two piles and put one in each hand getting me to chose a hand. This process was repeated a couple more time with the result that the F8 was the one that I ended up with.

I bought the kit from the Bolton show a couple of years ago for £95 from the bring and buy stand and this is what was in the box.



At the time the kit was £115 from Slaters without wheels so I counted myself as getting a reasonable deal with the wheels and the photos. The only basic thing that seems to be missing is brake blocks but I will pcik up a pack of the Slaters plastic ones at Telford.

Since getting back from my hols I have had it out of the box and done a bit of reading up in the RCTS green book albeit there isn't much on them.

I have a few dilemmas in terms of I do, do I:

1. Make it spilt axle? If so how would I accommodate point 2?

2. Make radial trucks - I have the MRJ article where Laurie Griffin made some.

3. Fit working valve gear - my reading tells me that these had JOY single slide bar valve gear so I would have to buy some in and would it actually fit between the chassis? Out of the box the chassis is a fold up type and I suspect that I may need to separate the frames and make new spacers to do this.

4. Fit dummy Valve gear - Could the Gladiator dummy JOY valve gear be modified to represent the NER version (giving me quite a saving over buying working parts from Laurie Griffin?

5. Do I replace the radial truck wheel sets - I ask because I have never used Gibson wheels in this scale before and they are 3'8" diameter not the 3' 9" that were fitted to the F8's? My initial thinking is that I could probably get away with this discrepancy due to my plan to model it in the mid 1930's when there may have been some wear on the tyres by then.

So many questions and any thoughts/experiences on some of my questions will be gratefully received.

Thought you'd been away on a South seas cruise (sold a few locos) expecting you to drop in

Eight kits what are they? so we can all drool over the keyboard

Hi Manna,

A cruise yes, South Seas no - just the opposite in fact. We went up into the Arctic Circle to the North Cape of Norway. The land of Polar bears, Reindeer and the midnight sun.

Tank engines besides the F8 in the pile are:

J52 - Ace Products
Y5 - Ace Products - with replacement castings from Ragstone
J68 - Connoisseur
N10 Connoisseur
F3 - Profile milled parts from Colin Dowling + castings from various sources. I have everything for this except the axle boxes for the radial trucks
F4/5 Shedmaster/Laurie Griffin
Sentinel Shunter - Meteor Models.

A little bird informs me that Christmas will add a Warren Sheppard N2 to the list.

Hi Rob,

I've also got an Ace J52 in the drawer(s). I had a look and was slightly perturbed by the pre-formed saddle tank. It's form is more like a GWR Pannier. I think there will be interesting times ahead for both of us!

That's a nice selection to keep you going this coming winter.

Arctic ocean, Polar bears, icebergs...............ships, haven't we seen that movie !!! think I'll keep to place's that are a lot warmer, and the only dangerous thing is a falling coconut

Now you have shattered all my illusions about OZ.

I believed that you took your life in your own hands every day with all the deadly spiders snakes etc. wandering the suburbs :

Oh, but they do but being so much smaller than us they try to keep out of our way, haven't seen a red back spider or snake in months, far more likely to be killed by a bee sting than a croc or a shark.

Hi Vernon, I agree on that one, although Ken Mason (Jazz) on RMweb recommended the kit to me having built one himself.

It was one of the kits that I was trying to decide on when Chris suggested the lottery.

My Mojo is returning so I have made a small start on the F8 in so much as Having had a looked at Premier's site and not finding any suitable replacement coupling rods (and hearing about long waits for bespoke stuff). Working on the theory that I have nothing to lose but a bit of time, I soldered together the Slaters steel coupling rods and cleaned them up - they look a lot better to the naked eye thank they do in the photo....

Leaving them looking like this



I still need to open out the holes for the crank pin bushes.

Having had quite a few bits of advice/suggestions I have ultimately decided on:

• Radial trucks front and rear but shorted out one side only and picking up one from each side and I will see how I get on with the Gibson wheels – Slaters don’t do the correct size either so worn it will be. If I have any problems with the Gibsons I will replace them with Slaters.
• Working inside motion but the crank axle wheels will only be shorted to the crank pin and will use the coupling rods to pass the current.
• Split axle for the remaining drive axle.

[Robpulham]

Well I have fallen at the first hurdle - looking at the Gibson wheels I realised that there is no metal centre boss to short the rims out to - this has been mentioned in several replies but I hadn't taken it on board. A visit to Slaters at Telford for replacements is now on the cards

[Robpulham]

Here is where I admit to a proper Doh!! moment.

Last night I realised that the safety valve bonnet in the kit is a white metal casting - a very nice whitemetal casting to be fair. But I want to be able to finish it as polished brass. While I could probably paint it brass coloured and varnish it, I would rather it be brass and with a lever (which mine hasn't got at present although I could no doubt make one up from some scrap etch).

I have a Laurie Griffin/Shedmaster LNER J24/25 kit in my stash so I thought that I would have a look at the safety valve cover to see if it was what I had in mind. (to add it to the list of things that I need to get from Laurie at Telford). While looking I noticed that the tender wheels were Slaters 3' 9" 10 spoke LNWR General Pattern..... A quick check in my F5 kit revealed two axles Slaters 3' 9" 10 spoke LNWR General Pattern.....

Having got all the chores in the garden out of the way in preparation for the landscapers coming the Mojo returned in force and yesterday I shorted out the wheels and blackened them (tapping the threads 10ba and fitting 10ba screws). I then drilled out an axle ready for epoxying GRP rod down the centre and blackened and made a start on drilling out the coupling rods.

It feels good to have made a start on it.





I also discovered while looking at the various bits and pieces that there isn't a back head so I have one on order from Laurie Griffin - my Telford shopping list grows!

The observant amongst you will have noticed the 2 shorted out Slaters bogie wheels? Having realised that I had them in stock I chickened out of messing with the Gibson's and they are destined for the Bay of E. I had nicely finished blackening them and cleaned up when I realised that I should have done both pairs:0(

[Robpulham]

I am slowly but surely making progress.

I have now prepared the axles for epoxying. The observant among you will note that there are more axles than I need splitting for the F8 here. I had already drilled out the centres of 3 axles previously for one of my other tanks so I decided to drill a fourth the only one that I need for the F8 and then do the rest of the splitting on the four. Working on the mix plenty of epoxy up that every article on split axles that I have read recommends it seemed sensible to do a few while I have the job on the go.

In the main I followed Steph's nicely documented method found here: http://www.euram-online.co.uk/tips/spli ... taxle3.htm

The only deviations from Steph's methods are that I used my pillar drill to drill out the axles and having tried a diamond slitting disk, as Steph recommends for cutting the GRP rod, I still got some fraying.

My alternative was to roll a scalpel blade backwards and forwards over it until it cut through (much like you would to cut microbore tube). It took a little longer but resulted in a nice clean cut with no fraying.


There are more holes than are visible in the photo above I just did a poor job of positioning them for the photo.

Next job is the messy one - epoxy here I come....

[Robpulham]

Despite having quite a busy social life at present with one thing and another I have still made some progress on the F8

I finished splitting the axles - they just need a final clean up - only one of these is for the F8 though (the one with the two splits)



And here's the one that got away - I was doing them last thing at night and I can only surmise that I didn't take enough time to work the epoxy fully through the spilt. The upside is that I can make use of the stub axles....... or so I am telling myself.

I assume that Slaters sell single axles?



While the epoxy has been drying I also made small start on assembling the boiler.



As you can see from the photo the boiler bands are formed from a half etched recess and then an etched strip that fit's in the recess but has folds/holes etched in for the cleats. I wondered if I could use a scale hardware stud to represent the fastener.





I have only done the one so far (and I need to centre it yet) - from the instructions there are two that will be visible beyond the ends of tanks. The rest need to be cut short when a cut out is made for the motor.

[Robpulham]

The sun shone very nicely in our part of the world today. So having done some chores yesterday and bearing in mind Chris's desire to get me out in the garden more I took some modelling out into the garden today.

The chores took the form of making a walkway across the stream bed.



Chris took a couple of shots of me modelling in the garden just in case it never happens again




The modelling tool the form of cutting out for the hornblocks/guides on the chassis and drilling out all the rivets - the etched marks that Slaters/Rising Star have on the etches are way too big so I plan to use some lace pin heads as the Scale hardware rivets that I have in stock are all quite small.

[Robpulham]

And this is the product of todays efforts



And the ash pan and motion plate that was included with the kit. I will use this as a template to make one that fits my inside motion.
